Application Precautions

• Emergency stop circuits, interlock circuits, limit circuits, and similar safety

measures must be provided in external control circuits.

• The PC will turn OFF all outputs when its self-diagnosis function detects any

error or when a severe failure alarm (FALS) instruction is executed. As a coun-

termeasure for such errors, external safety measures must be provided to en-

sure safety in the system.

• The PC outputs may remain ON or OFF due to deposition or burning of the

output relays or destruction of the output transistors. As a countermeasure for

such problems, external safety measures must be provided to ensure safety in

the system.

WARNING When transferring programs to other nodes, or when making changes to I/O

memory, confirm the safety of the destination node before transfer. Not doing so

may result in injury.

Caution Execute online edit only after confirming that no adverse effects will be caused

by extending the cycle time. Otherwise, the input signals may not be readable.

Application Precautions

• Mounting or dismounting the CPU board or expansion I/O board.

• Setting switches or rotary switches.

• Connecting or wiring the cables.

• Connecting or disconnecting the connectors.

Caution Failure to abide by the following precautions could lead to faulty operation of the

PC or the system, or could damage the PC. Always heed these precautions.

• Fail-safe measures must be taken by the customer to ensure safety in the

event of incorrect, missing, or abnormal signals caused by broken signal lines,

momentary power interruptions, or other causes.

• Construct a control circuit so that power supply for the I/O circuits does not

come ON before power supply for the PC. If power supply for the I/O circuits

comes ON before power supply for the PC, normal operation may be tempo-

rarily interrupted.

• If the operating mode is changed from RUN or MONITOR mode to PROGRAM

mode, with the IOM Hold Bit ON, the output will hold the most recent status. In

such a case, ensure that the external load does not exceed specifications. (If

operation is stopped because of an operation error (including FALS instruc-

tions), the values in the internal memory of the CPU board will be saved, but

the outputs will all turn OFF.)

• Always use the power supply voltage specified in the operation manuals. An

incorrect voltage may result in malfunction or burning.

• Take appropriate measures to ensure that the specified power with the rated

voltage is supplied. Be particularly careful in places where the power supply is

unstable. An incorrect power supply may result in malfunction.

• Install external breakers and take other safety measures against short-circuit-

ing in external wiring. Insufficient safety measures against short-circuiting may

result in burning.

• Do not apply voltages to the input terminals in excess of the rated input voltage.

Excess voltages may result in burning.

• Do not apply voltages or connect loads to the output terminals in excess of the

maximum switching capacity. Excess voltage or loads may result in burning.

• Be sure that all the mounting screws, terminal screws, and cable connector

screws are tightened to the torque specified in the relevant manuals. Incorrect

tightening torque may result in malfunction.

• When wiring the CPM2B, take countermeasures to prevent wiring cuttings

from coming into contact with the product, such as covering the whole product

with a dustproof cover. If wiring cuttings adhere to the PCB or circuit elements

they may cause short-circuiting.

• Be sure to perform wiring in accordance with the relevant operation manual.

Incorrect wiring may result in burning.

• Double-check all the wiring before turning ON the power supply. Incorrect wir-

ing may result in burning.

• Be sure that the terminal blocks, expansion cables, and other items with lock-

ing devices are properly locked into place. Improper locking may result in mal-

function.

• Be sure that terminal blocks and connectors are connected in the specified di-

rection with the correct polarity. Not doing so may result in malfunction.

• Check the user program for proper execution before actually running it on the

PC. Not checking the program may result in an unexpected operation.

• Confirm that no adverse effect will occur in the system before attempting any of

the following. Not doing so may result in an unexpected operation.

EC Directives

6-1

Applicable Directives

• EMC Directives

• Low Voltage Directive

6-2

Concepts

EMC Directives

OMRON devices that comply with EC Directives also conform to the related

EMC standards so that they can be more easily built into other devices or the

overall machine. The actual products have been checked for conformity to EMC

standards (see the following note). Whether the products conform to the stan-

dards in the system used by the customer, however, must be checked by the

customer.

EMC-related performance of the OMRON devices that comply with EC Direc-

tives will vary depending on the configuration, wiring, and other conditions of the

equipment or control panel on which the OMRON devices are installed. The cus-

tomer must, therefore, perform the final check to confirm that devices and the

overall machine conform to EMC standards.

Note Applicable EMC (Electromagnetic Compatibility) standards are as follows:

EMS (Electromagnetic Susceptibility): EN61131-2

EMI (Electromagnetic Interference):

EN50081-2

(Radiated emission: 10-m regulations)

Low Voltage Directive

Always ensure that devices operating at voltages of 50 to 1,000 VAC and 75 to

1,500 VDC meet the required safety standards for the PC (EN61131-2).

EC Directives

6-3

Conformance to EC Directives

The CPM2B PCs comply with EC Directives. To ensure that the machine or de-

vice in which the CPM2B PC is used complies with EC directives, the PC must be

installed as follows:

1, 2, 3...

1. The CPM2B PC must be installed within a control panel.

2. Reinforced insulation or double insulation must be used for the DC power

supplies used for the communications and I/O power supplies.

3. CPM2B PCs complying with EC Directives also conform to the Common

Emission Standard (EN50081-2). Radiated emission characteristics (10-m

regulations) may vary depending on the configuration of the control panel

used, other devices connected to the control panel, wiring, and other condi-

tions. You must therefore confirm that the overall machine or equipment

complies with EC Directives.

6-4

Relay Output Noise Reduction Methods

The CPM2B PCs conform to the Common Emission Standards (EN50081-2) of

the EMC Directives. However, the noise generated when the PC is switched ON

or OFF using the relay output may not satisfy these standards. In such a case, a

noise filter must be connected to the load side or other appropriate countermea-

sures must be provided external to the PC.

Countermeasures taken to satisfy the standards vary depending on the devices

on the load side, wiring, configuration of machines, etc. Following are examples

of countermeasures for reducing the generated noise.

Countermeasures

(Refer to EN50081-2 for more details.)

Countermeasures are not required if the frequency of load switching for the

whole system with the PC included is less than 5 times per minute.

Countermeasures are required if the frequency of load switching for the whole

system with the PC included is 5 times or more per minute.

Countermeasure Examples

When switching an inductive load, connect a surge protector, diodes, etc., in par-

allel with the load or contact as shown below.

If the load is a relay or solenoid, there The capacitance of the capacitor must

is a time lag between the moment the be 1 to 0.5 µF per contact current of

circuit is opened and the moment the

load is reset.

1 A and resistance of the resistor must

be 0.5 to 1 Ω per contact voltage of

1 V. These values, however, vary with

the load and the characteristics of the

relay. Decide these values from

experiments, and take into

consideration that the capacitance

suppresses spark discharge when the

contacts are separated and the

resistance limits the current that flows

into the load when the circuit is closed

again.

If the supply voltage is 24 to 48 V,

insert the surge protector in parallel

with the load. If the supply voltage is

100 to 200 V, insert the surge

CPM2B Features and Functions

Section 1-1

1-1 CPM2B Features and Functions

1-1-1 CPM2B Features

The CPM2B PCs are compact Board PCs that can be incorporated easily into

control equipment. The PCs are equipped with a variety of advanced features

including synchronized pulse control, interrupt inputs, high-speed counters,

pulse outputs, and a clock function.

• The compact Board design is ideal for incorporation into control equipment.

• The CPU Board itself can handle a wide range of machine control applications,

so it is ideal for use as a built-in control unit in control equipment.

• The CPM2B is equipped with a full complement of communications functions

to provide communications with personal computers, other OMRON PCs, and

OMRON Programmable Terminals. These communications capabilities allow

the user to design a low-cost distributed production system.

Peripheral Port

RS-232C Port

Programming Devices are compatible with other

models of OMRON PCs. This port can also be used

for Host Link or no-protocol communications.

This port can be used for a Host Link,

no-protocol, 1:1 PC Link, or 1:1 NT Link

communications.

Transistor Output Board

Relay Output Board

The CPU Board has 32 I/O points and Expansion

I/O Boards can be added to provide a total I/O ca-

pacity of up to 128 I/O points.

Basic Functions

CPU Board I/O

The CPM2B CPU Board itself is equipped with 32 I/O points in I/O terminals or

I/O connectors. There are 2 types of outputs available (relay outputs and sinking

transistor outputs). The power supply is 24 V DC only.

Expansion I/O Boards

Up to 3 Expansion I/O Boards can be connected to the CPU Board to increase

the PC’s I/O capacity to a maximum of 128 I/O points. There are 2 types of

32-point Expansion I/O Boards available: one with relay outputs and the other

with sinking transistor outputs.

Share Programming

Devices

The same Programming Devices, such as Programming Consoles and Support

Software, can be used for the C200H, C200HS, C200HX/HG/HE, CQM1,

CPM1, CPM1A, CPM2A, CPM2C, and SRM1 (-V2) PCs, so existing ladder pro-

gram resources can be used effectively.

Built-in Motor Control Capability

Synchronized Pulse

Control

(Transistor Outputs Only)

Synchronized pulse control provides an easy way to synchronize the operation

of a peripheral piece of equipment with the main equipment. The output pulse

frequency can be controlled as some multiple of the input pulse frequency, al-

lowing the speed of a peripheral piece of equipment (such as a supply conveyor)

to be synchronized with the speed of the main piece of equipment.

Motor driver Motor

Encoder

CPM2B

Pulses are output as a fixed multiple of the input frequency.

High-speed Counters and

Interrupts

The CPM2B has a total of five high-speed counter inputs. The one high-speed

counter input has a response frequency of 20 kHz/5 kHz and the four interrupt

inputs in counter mode have a response frequency of 2 kHz.

The high-speed counter can be used in any one of the four input modes: differen-

tial phase mode (5 kHz), pulse plus direction input mode (20 kHz), up/down

pulse mode (20 kHz), or increment mode (20 kHz). Interrupts can be triggered

when the count matches a set value or falls within a specified range.

The interrupt inputs in counter mode can be used for incrementing counters or

decrementing counters (2 kHz) and trigger an interrupt (executing the interrupt

program) when the count matches the target value.

Easy Position Control

with Pulse Outputs

(Transistor Outputs Only)

CPM2B PCs with transistor outputs have two outputs that can produce 10 Hz to

10 kHz pulses (single-phase outputs).

When used as single-phase pulse outputs, there can be two outputs with a fre-

quency range of 10 Hz to 10 kHz with a fixed duty ratio or 0.1 to 999.9 Hz with a

variable duty ratio (0 to 100% duty ratio).

When used as pulse plus direction or up/down pulse outputs, there can be just

one output with a frequency range of 10 Hz to 10 kHz.

High-speed Input Capabilities for Machine Control

High-speed Interrupt

Input Function

There are four inputs used for interrupt inputs (shared with quick-response in-

puts and interrupt inputs in counter mode) with a minimum input signal width of

50 µs and response time of 0.3 ms. When an interrupt input goes ON, the main

program is stopped and the interrupt program is executed.

Quick-response Input

Function

There are four inputs used for quick-response inputs (shared with interrupt in-

puts and interrupt inputs in counter mode) that can reliably read input signals

with a signal width as short as 50 µs.

Stabilizing Input Filter

Function

The input time constant for all inputs can be set to 1 ms, 2 ms, 3 ms, 5 ms,

10 ms, 20 ms, 40 ms, or 80 ms. The effects of chattering and external noise can

be reduced by increasing the input time constant.

Other Functions

Interval Timer Interrupts

The interval timer can be set between 0.5 and 319,968 ms and can be set to gen-

erate just one interrupt (one-shot mode) or periodic interrupts (scheduled inter-

rupt mode).

Analog Settings

There are two controls on the CPU Board that can be turned to change the ana-

log settings (0 to 200 BCD) in IR 250 and IR 251. These controls can be used to

easily change or fine-tune machine settings such as a conveyor belt’s pause

time or feed rate.

DIP Switch Inputs

Calendar/Clock

A DIP switch is provided that controls the status of four input bits.

The built-in clock (accuracy within 1 minute/month) can be read from the pro-

gram to show the current year, month, day, day of the week, and time. The clock

can be set from a Programming Device (such as a Programming Console) or the

time can be adjusted by rounding up or down to the nearest minute.

Long-term Timer

TIML(––) is a long-term timer that accommodates set values up to 99,990 sec-

onds (27 hours, 46 minutes, 30 seconds). When combined with the SECONDS

size or micro PCs. Using the CPM1-EMU01-V1, simple on-site transfer of user

programs and data memory is possible with PCs.

Complete Communications Capabilities

Host Link

A Host Link connection can be made through the PC’s RS-232C port or Periph-

eral port. A personal computer or Programmable Terminal connected in Host

Link mode can be used for operations such as reading/writing data in the PC’s

I/O memory or reading/changing the PC’s operating mode.

Note 1. The NT-AL001-E must be supplied externally with 5 V DC. When an NT-

AL001-E is connected to a CPM2B PC, pin 6 of the CPM2B’s RS-232C port

supplies +5 V DC and an external power supply is not necessary. When the

NT-AL001-E is connected to a host computer, it is necessary to supply 5 V

DC from an external power supply.

If an NT-AL001-E is connected to the CPM2B’s RS-232C port, only one Ex-

pansion I/O Board can be connected to the CPU Board because the NT-

AL001-E draws its 5-V DC power from the CPU Board.

Use an XW2Z-070T-1 (0.7 m) or XW2Z-200T-1 (2 m) cable to connect the

NT-AL001-E to the CPM2B’s RS-232C port.

2. The 3G2A9-AL004-E requires an external AC power supply (110 V AC or

220 V AC).

3. The CPM1-CIF11 is supplied +5 V DC from the peripheral port so an exter-

nal power supply is not necessary.

I/O Memory

The program reads and writes data in this memory area during execution. Part of

the I/O memory contains the bits that reflect the status of the PC’s inputs and

outputs. Parts of the I/O memory are cleared when the power is turned ON and

other parts are retained.

Note Refer to Section 4 Memory Areas for more details on I/O memory.

Program

PC Setup

This is the program written by the user. The CPM2B executes the program cycli-

cally. (Refer to 1-3-5 Cyclic Operation and Interrupts for details.)

The program can be divided broadly into two parts: the “main program” that is

executed cyclically and the “interrupt programs” that are executed only when the

corresponding interrupt is generated.

The PC Setup contains various startup and operating parameters. The PC Set-

up parameters can be changed from a Programming Device only; they cannot

be changed from the program.

Some parameters are accessed only when PC’s power supply is turned on and

others are accessed regularly while the power is on. It will be necessary to turn

the power off and then on again to enable a new setting if the parameter is ac-

cessed only when the power is turned on.

Note Refer to 4-5 PC Setup for more details.

Communications

Switches

The Communications Switches determine whether the peripheral port and

RS-232C port operate with the standard communications settings or the com-

munications settings in the PC Setup. Refer to 2-2 Board Components and their

Functions for more details.

Structure and Operation

Section 1-3

1-3-2 Operating Modes

CPM2B CPU Boards have 3 operating modes: PROGRAM, MONITOR, and

RUN.

PROGRAM Mode

The program cannot be executed in PROGRAM mode. This mode is used to

perform the following operations in preparation for program execution

• Changing initial/operating parameters such as those in the PC Setup

• Writing, transferring, or checking the program

• Checking wiring by force-setting and force-resetting I/O bits

Caution The PC continues to refresh I/O bits even if the PC is in PROGRAM mode, so

devices connected to output points on the CPU Board or Expansion I/O Boards

may operate unexpectedly if the corresponding output bit is turned ON by

changing the contents of I/O memory from a Programming Device.

MONITOR Mode

The program is executed in MONITOR mode and the following operations can

be performed from a Programming Device. In general, MONITOR mode is used

to debug the program, test operation, and make adjustments.

• Online editing

• Monitoring I/O memory during operation

• Force-setting/force-resetting I/O bits, changing set values, and changing pres-

ent values during operation

RUN Mode

The program is executed at normal speed in RUN mode. Operations such as

online editing, force-setting/force-resetting I/O bits, and changing set values/

present values cannot be performed in RUN mode, but the status of I/O bits can

be monitored.

1-3-3 Operating Mode at Startup

The operating mode of the CPM2B when the power is turned ON depends upon

the PC Setup settings and the Programming Console’s mode switch setting if a

Programming Console is connected.

2. The default setting of bits 08 to 15 of DM 6600 is 00. With this default setting,

the PC will automatically enter RUN mode if a Programming Console is not

connected and SW201 is ON. Be sure that it is safe for the PC to operate

before turning it ON under these conditions.

Structure and Operation

Section 1-3

1-3-4 PC Operation at Startup

Time Required for

Initialization

The time required for startup initialization depends on several factors, such as

the operating conditions (including power supply voltage, system configuration,

and ambient temperature) and the program contents.

Power OFF Operation

Minimum Power Supply Voltage

The PC will stop and all outputs will be turned OFF if the power supply voltage

falls below 85% of the rated value.

Momentary Power Interruption

A power interruption will not be detected and CPU Board operation will continue

if the power interruption lasts less than 2 ms for a DC power supply.

A power interruption may or may not be detected for power interruptions some-

what longer than 2 ms for a DC power supply.

When a power interruption is detected, the CPU Board will stop operating and all

outputs will be turned OFF.

Automatic Reset

Operation will restart automatically when the power supply voltage is restored to

more than 85% of the rated voltage.

Timing Chart of Power OFF Operation

The power interruption detection time is the time required for a power interrup-

tion to be detected after the power supply voltage drops below 85% of the rated

value.

Note If the power supply voltage fluctuates around 85% of the PC’s rated voltage, PC

operation may stop and restart repeatedly. When repeated stopping and starting

will cause problems with the controlled system, set up a protective circuit such

as a circuit that shuts off the power supply to sensitive equipment until the power

supply voltage returns to the rated value.

Structure and Operation

Section 1-3

1-3-5 Cyclic Operation and Interrupts

Basic CPU Operation

Initialization processing is performed when the power is turned on. If there are no

initialization errors, the overseeing processes, program execution, I/O refresh-

ing, and communications port servicing are performed repeatedly (cyclically).

S Check hardware.

S Check memory.

Startup initialization

S Read data from flash memory (program,

read-only DM data, and PC Setup settings).

S Check for battery error.

Overseeing

processes

S Preset the watch (maximum) cycle time.

S Check program memory.

S Refresh bits for expansion functions.

S Execute the program.

(Refer to the Programming Manual (W353) for

details on cycle time and I/O response times.)

Program execution

S Wait for minimum cycle time if a minimum

cycle time has been set in the PC Setup

(DM 6619).

Cycle time

calculation

S Calculate cycle time.

S Read input data from input bits.

I/O refreshing

S Write output data to output bits.

RS-232C port

servicing

S Perform RS-232C port communications

processing. (Can be changed in DM 6616.)

Peripheral port

servicing

S Perform Peripheral port communications

processing. (Can be changed in DM 6617.)

The cycle time can be read from a Programming Device.

AR 14 contains the maximum cycle time and AR 15 contains the present cycle

time in 4-digit BCD.

Download from Www.Somanuals.com. All Manuals Search And Download.

Structure and Operation

Section 1-3

The cycle time will vary slightly depending on the processing being performed in

each cycle, so the calculated cycle time will not always match the actual cycle

time.

Program Execution in

Cyclic Operation

The following diagram shows the cyclic operation of the CPM2B when the pro-

gram is being executed normally.

Normally, the results of program execution are transferred to I/O memory just

after program execution (during I/O refreshing), but IORF(97) can be used to re-

fresh a specified range of I/O words during program execution. The specified

range of I/O words will be refreshed when IORF(97) is executed.

The cycle time is the sum of the time required for program execution, I/O refresh-

ing, and communications port servicing.

A minimum cycle time (1 to 9,999 ms) can be set in the PC Setup (DM 6619).

When a minimum cycle time has been set, CPU operation is paused after pro-

gram execution until the minimum cycle time is reached. CPU operation will not

be paused if the actual cycle time is longer than the minimum cycle time set in

DM 6619.

Note A fatal error will occur and PC operation will stop if a maximum cycle time has

been set in the PC Setup (DM 6618) and the actual cycle time exceeds that set-

ting.

The default settings for RS-232C port servicing and Peripheral port servicing are

5% of the cycle time, but these settings can be changed (between 1% and 99%)

in the PC Setup. The RS-232C port’s setting is in DM 6616 and the Peripheral

port’s setting is in DM 6617.

Structure and Operation

Section 1-3

Interrupt Program

Execution

When an interrupt is generated during execution of the main program, main pro-

gram execution is interrupted immediately and the interrupt program is execut-

ed. The following diagram shows the cyclic operation of the CPM2B when an

interrupt program is executed.

Normally, the results of interrupt program execution are transferred to I/O

memory just after program execution (during I/O refreshing), but IORF(97) can

be used to refresh a specified range of I/O words during execution of the inter-

rupt program. The specified range of I/O words will be refreshed when IORF(97)

is executed.

The normal cycle time is extended by the time required for execution of the inter-

rupt program.

Refer to Section 7 PC Operations and Processing Time in the CPM1/CPM1A/

CPM2A/CPM2C/SRM1(-V2) Programmable Controllers Programming Manual

(W353) for more details and precautions on the cycle time.

Caution Although IORF(97) can be used in interrupt subroutines, you must be careful of

the interval between IORF(97) executions. If IORF(97) is executed too frequent-

ly, a fatal system error may occur (FALS 9F), stopping operation. The interval

between executions of IORF(97) should be at least 1.3 ms + total execution time

of the interrupt subroutine.

Immediate Refreshing

IORF(97) can be executed in the program to refresh a specified range of I/O

words. The specified I/O words will be refreshed when IORF(97) is executed.

IORF(97) can be used to refresh I/O from the main program or the interrupt pro-

gram.

Selecting an Installation Site

Section 3-2

3-1 Design Precautions

Observe the following precautions when designing a system incorporating a

CPM2B PC.

3-1-1 Power Supply Wiring

Separate the power supply wiring from the power system, control system,

CPM2B system, and DC I/O system wiring. Separate the control circuits that

supply power to the main Unit from the main circuits using dedicated circuit pro-

tectors and fuses.

3-1-2 Power Supply Voltage

Caution Use the power supply voltages indicated in Section 2-1 Specification. Failure to

adhere to the specifications may result in fire.

If the power supply voltage falls below 85% of the rated voltage, the CPM2B will

stop and all outputs will be turned OFF. If low voltage affects the equipment, etc.,

provide a protection circuit which shuts off the output until the supply voltage re-

turns to the rated value.

In places where power supply conditions are poor, take steps to ensure that

power is supplied at the rated voltage. Be sure to adhere to safety precautions,

such as providing breakers to prevent short circuits in external wiring.

When conducting any of the following operations, turn OFF the power to the PC.

Electrocution, product damage and malfunction may result.

• Connecting or disconnecting Expansion I/O Boards and CPU Boards.

• Assembling equipment.

• Connecting cables and wiring.

3-1-3 Interlock and Limit Circuits

WARNING Emergency stop circuits, interlock circuits, limit circuits, and similar safety

measures must be provided in external control circuits (i.e., not in the

Programmable Controller) to ensure safety in the system if an abnormality

occurs due to malfunction of the PC or another external factor affecting the PC

operation. Not providing proper safety measures may result in serious

accidents.

The following diagram shows an example of an interlock circuit.

Leakage Current

A leakage current can cause false inputs when using 2-wire sensors (proximity

switches or photoelectric switches) or limit switches with LEDs. False inputs

won’t occur if the leakage current is less than 1.0 mA (2.5 mA for IN00000 to

IN00002). If the leakage current exceeds these values, insert a bleeder resistor

in the circuit to reduce the input impedance, as shown in the following diagram.

Precautions

Observe the following precautions to protect the PC’s internal components.

Output Short Protection

The output or internal circuitry might be damaged when the load connected to an

output is short-circuited, so it is recommended to install a protective fuse in each

output circuit.

Inductive Loads

When connecting an inductive load to an input, connect a surge protector or

diode in parallel with the load.

Note 1. Input bits IR 00108 to IR 00111 reflect the status of the DIP switch on the

CPU Board.

2. The contents of the HR area, AR area, Counter area, and read/write DM

area are backed up by the CPU Board’s backup battery or capacitor. If the

battery or capacitor discharges completely, memory contents will be re-

turned to their default settings.

3. The program and data in DM 6144 to DM 6655 are stored in flash memory.

4-1-1 Functions

IR Area

The functions of the IR area are explained below.

IR area bits in the input and output areas are allocated to terminals on the CPU

Board and Expansion I/O Boards. They reflect the ON/OFF status of input and

output signals. Input bits begin at IR 00000, and output bits begin at IR 01000.

I/O Allocation

Section 4-2

IR words that are not allocated to inputs or outputs can be used as work words.

Work Bits

SR Area

The work bits can be used freely within the program. They can only be used with-

in the program, however, and not for direct external I/O.

These bits mainly serve as flags for CPM2B operation or contain present and set

values for various functions. SR 253 to SR 255 are read-only. Refer to 4-3 SR

Area for details on the various bit functions.

TR Area

When a complex ladder diagram cannot be programmed in mnemonic code just

as it is, these bits are used to temporarily store ON/OFF execution conditions at

program branches. They are used only for mnemonic code. When programming

directly with ladder diagrams using the Support Software, TR bits are automati-

cally processed for you.

The same TR bits cannot be used more than once within the same instruction

block, but can be used again in different instruction blocks. The ON/OFF status

of TR bits cannot be monitored from a Programming Device.

HR Area

AR Area

LR Area

These bits retain their ON/OFF status even after the PC power supply has been

turned off or when operation begins or stops. They are used in the same way as

work bits.

These bits mainly serve as flags related to PC operation. These bits retain their

status even after the PC power supply has been turned off or when operation

begins or stops. Refer to 4-4 AR Area for details on the various bit functions.

When the CPM2B is linked 1:1 with another CPM2B or a CPM1/CPM1A/

CPM2A/CPM2C/SRM1(-V2), a CQM1, a C200HS or a C200HX/HG/HE PC,

these bits are used to share data.

LR words can be used as work words when they are not used for a 1:1 PC Link.

Timer/Counter Area

This area is used to manage timers and counters created with TIM, TIMH(15),

TMHH(––), TIML(––), CNT, and CNTR(12). The same numbers are used for

both timers and counters and each number can be used only once in the user

program. Do not use the same TC number twice even for different instructions.

Use TC numbers 000 to 003 for TIMH(15) and TC numbers 004 to 007 for

TMHH(––). When these timer numbers are used, timing is performed as an in-

terrupt process and the cycle time is not affected.

TC numbers are used to create timers and counters, as well as to access

Completion Flags and present values (PVs). If a TC number is designated for

word data, it will access the present value (PV); if it is used for bit data, it will ac-

cess the Completion Flag for the timer/counter.

DM Area

DM area data is accessed in word units only. The contents of the DM area are

retained even after the PC power supply has been turned off or when operation

begins or stops.

DM words DM 0000 to DM 1999 and DM 2022 to DM 2047 can be used freely in

the program; other DM words are allocated specific functions.

DM 2000 to DM 2021 contain the error log information. Refer to Section 4-6 Error

Log for details on the error log.

DM 6600 to DM 6655 contain the PC Setup. Refer to 4-5 PC Setup for details.

4-2 I/O Allocation

IR bits are allocated to actual input terminals and output terminals on the CPU

Board and Expansion I/O Boards. IR words that are not allocated to inputs or

outputs can be used as work words.

4-5 PC Setup

The PC Setup comprises various operating parameters that control PC opera-

tion. In order to make the maximum use of PC functionality when using interrupt

processing and communications functions, the PC Setup may be customized

according to operating conditions.

After the PC Setup has been changed, be sure to switch the CPM2B to MON-

ITOR or RUN mode or turn the power OFF and then ON again.

4-5-1 Changing the PC Setup

The PC Setup settings in DM 6600 to DM 6655 can be changed from a Program-

ming Device. The CPM2B must be in PROGRAM mode in order to change the

settings in DM 6600 to DM 6644. The settings in DM 6645 to DM 6655 can be

changed in MONITOR or PROGRAM mode, but CPM2B’s cycle time will be long

if the settings are changed in MONITOR mode.

All of the PC Setup settings are set to their defaults when the CPM2B is shipped.

The default values for the PC Setup are 0000 for all words (except for the low

battery error enable in DM 6655 bits 12 to 15).

Effectiveness of Changes

PC Setup settings are accessed at various times depending on the setting, as

described below.

Errors in the PC Setup

If an incorrect PC Setup setting is accessed, a non-fatal error (error code 9B) will

be generated, the corresponding error flag (AR 1300 to AR 1302) will be turned

ON, and the default setting will be used instead of the incorrect setting.

Error Log Settings (DM 6655)

The following settings are effective after transfer to the PC.

DM 6655

00 to 03 Style

0: Shift after 7 records have been stored

1: Store only first 7 records (no shifting)

2 to F: Do not store records

04 to 07 Not used.

08 to 11 Cycle time monitor enable

0: Generate a non-fatal error for a cycle time that is too long.

1: Do not generate a non-fatal error.

12 to 15 Low battery error enable

0: Generate a non-fatal error for low battery voltage.

1: Do not generate a non-fatal error.

Low battery error detection is disabled (i.e., set to 1) by default in CPU Boards that do not have a

clock. If the PC Setup is cleared, the setting will changed to 0 and a low battery error will occur.

4-6 Error Log

The error log function registers the error code of any fatal or non-fatal error that

occurs in the PC. The date and time at which the error occurred are registered

along with the error code. The error code is also stored in AR 253.

The error log is stored in DM 2000 through DM 2021. Up to 7 error records can be

stored.

Error log pointer

Indicates the number of records stored in the log (0 to 7). A 0 indi-

cates no records.

Error Log Storage Methods

The error log storage method is set in the PC Setup (bits 00 to 03 of DM 6655).

Set any of the following methods.

1, 2, 3...

1. DM 6655 bits 00 to 03 set to 0:

Stores the most recent 7 error log records and discard older records. This is

achieved by shifting the records as shown below so that the oldest record

(record 0) is lost whenever a new record is generated.

Lost

Error log record 1

Error log record 2

All records shifted

Error log record 6

Error log record 7

New record added

2. DM 6655 bits 00 to 03 set to 1:

Stores only the first 7 error log records, and ignores any subsequent errors

beyond those 7.

3. DM 6655 bits 00 to 03 set to any value other than 0 or 1:

Disables the log so that no records are stored.

The default setting is the first method. Refer to the preceding page for details on

the error log settings in DM 6655.

Clearing the Error Log

To clear the entire error log, turn ON SR 25214 from a Programming Device. (Af-

ter the error log has been cleared, SR 25214 will turn OFF again automatically.)

Expansion Instructions

Section 5-3

5-3 Expansion Instructions

A set of expansion instructions is provided to aid in special programming needs.

Function codes can be assigned to up to 18 of the expansion instructions to en-

able using them in programs. This allows the user to pick the instructions needed

by each program to more effectively use the function codes required to input

instructions.

The mnemonics of expansion instructions are followed by “(––)” as the function

code to indicate that they must be assigned function codes by the user in the

instructions table before they can be used in programming (unless they are used

under their default settings).

Refer to the 6-2-5 Assigning Expansion Instruction Function Codes for a de-

scription of the Programming Console operations used to change expansion in-

struction allocations.

Refer to the SYSMAC Support Software Operation Manuals: C-series PCs

(W248), the SYSMAC-CPT Support Software User Manual (W333), or the

WS02-CXPC1-E CX-Programmer User Manual (W361) for a description of the

corresponding Support Software operations.

Function Codes for

Expansion Instructions

The following 18 function codes can be used for expansion instructions:

17, 18, 19, 47, 48, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 87, 88, and 89

The 35 expansion instructions that can be used are listed below, along with the

default function codes that are assigned when the CPM2B is shipped.

Operating Modes

PROGRAM Mode

The CPM2B program isn’t executed in PROGRAM mode. Use PROGRAM

mode to create and edit the program, clear memory, or check the program for

errors, or check output wiring.

MONITOR Mode

The CPM2B program is executed in MONITOR mode and I/O is processed just

as it is in RUN mode. Use MONITOR mode to test system operations, such as

monitoring CPM2B operating status, force-setting and resetting I/O bits, chang-

ing the SV/PV of timers and counters, changing word data, and online editing.

RUN Mode

This is the CPM2B’s normal operating mode. The CPM2B’s operating status can

be monitored from a Programming Device, but bits can’t be force-set/force-reset

and the SV/PV of timers and counters can’t be changed.

Caution Check the system thoroughly before changing the operating mode of the PC to

prevent any accidents that might occur when the program is first started.

Caution Never change the mode while pressing any of the keys.

This section describes the procedures required to begin Programming Console

operation when using the Programming Console for the first time.

Caution Always confirm that the Programming Console is in PROGRAM mode when

turning ON the PC with a Programming Console connected unless another

mode is desired for a specific purpose. If the Programming Console is in RUN

mode when PC power is turned ON, any program in Program Memory will be

executed, possibly causing a PC-controlled system to begin operation.

The following sequence of operations must be performed before beginning ini-

tial program input.

1, 2, 3...

1. Be sure that the PC is OFF.

2. Connect the Programming Console to the CPU Board’s peripheral port. See

6-1-3 Connecting the Programming Console for details.

8. Start programming.

6-1-5 Entering the Password

To gain access to the PC’s programming functions, you must first enter the pass-

word. The password prevents unauthorized access to the program.

The PC prompts you for a password when PC power is turned on or, if PC power

is already on, after the Programming Console has been connected to the PC. To

gain access to the system when the “Password!” message appears, press CLR

and then MONTR. Then press CLR to clear the display.

If the Programming Console is connected to the PC when PC power is already

on, the first display below will indicate the mode the PC was in before the Pro-

gramming Console was connected. Ensure that the PC is in PROGRAM mode

before you enter the password. When the password is entered, the PC will

shift to the mode set on the mode switch, causing PC operation to begin if the

mode is set to RUN or MONITOR. The mode can be changed to RUN or MON-

ITOR with the mode switch after entering the password.

Programming Console Operations

Section 6-2

6-2-24 Force Set, Reset

This operation is used to force bits ON (force set) or OFF (force reset) and is

useful when debugging the program or checking output wiring. It is possible

in MONITOR or PROGRAM mode only.

RUN

MONITOR

PROGRAM

Caution Before changing the contents of I/O memory, be sure that the changes will not

cause equipment to operate unexpectedly or dangerously. In particular, take

care when changing the status of output bits. The PC continues to refresh I/O

bits even if the PC is in PROGRAM mode, so devices connected to output points

on the CPU Board or Expansion I/O Boards may operate unexpectedly.

1, 2, 3...

1. Monitor the status of the desired bit according to the procedure described in

6-2-12 Bit, Digit, Word Monitor. If two or more words are being monitored,

the desired bit should be leftmost on the display.

The cursor in the lower left corner of the display indicates that the force set/

reset is in progress. Bit status will remain ON or OFF only as long as the key

is held down; the original status will return one cycle after the key is re-

leased.

3. Press the SHIFT and SET Keys or SHIFT and RESET Keys to maintain the

status of the bit after the key is released. In this case, the force-set status is

indicated by an “S” and the force-reset status is indicated by an “R.”

To return the bit to its original status, press the NOT Key or perform the Clear

Force Set/Reset operation. Refer to 6-2-25 Clear Force Set/Reset for de-

tails.

Forced status will also be cleared in the following cases:

a) When the PC’s operating mode is changed (although the forced status

will not be cleared when the mode is changed from PROGRAM to MON-

ITOR if SR 25211 is ON)

b) When the PC stops because a fatal error occurred

c) When the PC stops because of a power interruption

d) When the Clear Force Set/Reset Operation is performed

6-2-25 Clear Force Set/Reset

This operation is used to restore the status of all bits which have been force

set or reset. It is possible in MONITOR or PROGRAM mode only.

CPM2B Test Run Procedure

Section 7-2

7-1 Initial System Checks and Test Run Procedure

7-1-1 Initial System Checks

Check the following items after setting up and wiring the CPM2B, but before per-

forming a test run.

Item

Points to check

Power supply and

I/O connections

Is the wiring correct?

Are the terminals securely tightened?

Are there any shorts between crimp terminals or wires?

Refer to 3-5 Wiring and Connections for details.

Are the cables all connected correctly and locked?

Refer to 3-5 Wiring and Connections for details.

Connecting cables

Clearing Memory

Always clear memory before beginning to program the CPM2B. Although

memory is cleared before the CPU Board is shipped, the contents of the DM,

HR, AR, and counter areas may change in transit.

When a CPU Board without a clock is being used and the contents of DM have

been cleared, battery error detection must be disabled in the PC Setup by setting

the leftmost digit of DM 6655 to 1.

Operating Mode at

Startup

See 1-3-3 Operating Mode at Startup to determine what mode the CPM2B will

enter when the power is turned on.

7-1-2 Flash Memory Precautions

Observe the following precautions to protect the flash memory and ensure

proper operation.

1, 2, 3...

1. If changes are made in the read-only DM area (DM 6144 through DM 6599)

or PC Setup (DM 6600 through DM 6655), the PC’s operating mode must be

changed to write the new contents to flash memory. If backup battery is re-

placed before the changes are written to flash memory, the changes will be

lost.

The changes can be saved by switching the CPM2B to RUN or MONITOR

mode or turning the CPM2B OFF and then ON again.

2. When contents of the program, read-only DM (DM 6144 through DM 6599),

or PC Setup (DM 6600 through DM 6655) have been changed, startup proc-

essing will take up to 1,200 ms longer than usual. Be sure to take this one-

time startup delay into account if it may affect operations.

3. If one of the following three operations is performed in MONITOR or RUN

mode, the CPM2B’s cycle time will be extended by up to 1,200 ms and inter-

rupts will be disabled while the program or PC Setup is being overwritten.

• Program changes with the online edit operation

• Changes to the read-only DM area (DM 6144 through DM 6599)

• Changes to the PC Setup (DM 6600 through DM 6655)

A “SCAN TIME OVER” error won’t occur during these operations. Be sure to

take this delay in the CPM2B’s I/O response times into account when per-

forming online editing.

7-2 CPM2B Test Run Procedure

1, 2, 3...

1. Power Supply Application

a) Check the CPM2B’s power supply voltage and terminal connections.

b) Check the I/O devices’ power supply voltage and terminal connections.

c) Turn on the power supply and check that the “PWR” indicator lights.

114

Download from Www.Somanuals.com. All Manuals Search And Download.

Self-diagnostic Functions

Section 7-3

d) Use a Programming Device to set the CPM2B to PROGRAM mode.

2. I/O Wiring Checks

a) With the CPM2B in PROGRAM mode, check the output wiring by turning

on the output bits with the force set and force reset operations.

b) Check the input wiring with the CPM2B’s input indicators or a Program-

ming Device’s monitor operations.

3. Test Run

a) Use a Programming Device to set the CPM2B to RUN or MONITOR

mode and check that the “RUN” indicator lights.

b) Check the sequence of operation with the force set/reset operations, etc.

4. Debugging

Correct any programming errors that are detected.

5. Saving the Program

a) Use a Programming Device to write the program to a backup floppy disk.

b) Print out a hard copy of the program with a printer.

Note Refer to Section 4 Using Programming Devices for details on the Support Soft-

ware and Programming Console operations.

7-3 Self-diagnostic Functions

The CPM2B is equipped with a variety of self-diagnostic functions to help iden-

tify and correct errors and reduce down time.

7-3-1 Identifying Errors

An error can be identified by the error message displayed on a Programming

Device, error flags in the AR and SR areas, and the error code output to SR 253.

Fatal and Non-fatal

Errors

PC errors are divided into 2 categories based on the severity of the errors. The

status of the ERR indicator (lit or flashing) shows which type of error has oc-

curred.

ERR Lit (Fatal Error)

Fatal errors are serious errors which stop CPM2B operation. There are two ways

to restart operation:

• Turn the PC off and then on again.

• Use a Programming Device to switch the PC to PROGRAM mode, and read/

clear the error.

ERR Flashing (Non-fatal Error)

Non-fatal errors are less serious errors which don’t stop CPM2B operation.

Error Messages

Error Flags

When an error is detected, a corresponding error message will be displayed on

the Programming Console or other Programming Device connected to the PC.

When a hardware error is detected, the corresponding error flag in the AR or SR

area will be turned ON.

Error Code

When an error is detected, a specific 2-digit hexadecimal error code is output to

SR 25300 to SR 25307. The error code and time of occurrence are also output to

the Error Log Area (DM 2000 to DM 2021).

WARNING When the CPM2B’s self-diagnosis function detects a fatal error or when a

severe failure alarm (FALS) instruction is executed, PC operation will stop and

all outputs will be turned OFF. External safety measures must be provided to

ensure safety in the system. Not providing proper safety measures may result in

7-3-2 User-defined Errors

There are three instructions that can be used to define errors or messages.

FAL(06) causes a non-fatal error, FAL(07) causes a fatal error, and MSG(46)

sends a message to the Programming Console or host computer connected to

the PC.

FAILURE ALARM –

FAL(06)

FAL(06) is an instruction that causes a non-fatal error. The following will occur

when an FAL(06) instruction is executed:

1, 2, 3...

1. The ERR indicator on the CPU Board will flash. PC operation will continue.

2. The instruction’s 2-digit BCD FAL number (01 to 99) will be written to

SR 25300 to SR 25307.

The FAL numbers can be set arbitrarily to indicate particular conditions, but the

same number should not be used as both an FAL number and an FALS number.

To clear an FAL error, correct the cause of the error and then execute FAL 00 or

use a Programming Device to clear the error.

SEVERE FAILURE ALARM – FALS(07) is an instruction that causes a fatal error. The following will occur when

FALS(07)

an FALS(07) instruction is executed:

1, 2, 3...

1. Program execution will be stopped and all outputs will be turned OFF.

2. The ERR indicator on the CPU Board will be lit.

3. The instruction’s 2-digit BCD FALS number (01 to 99) will be written to

SR 25300 to SR 25307.

The FALS numbers can be set arbitrarily to indicate particular conditions, but the

same number should not be used as both an FAL number and an FALS number.

To clear an FALS error, use a Programming Device to switch the PC to PRO-

GRAM Mode, correct the cause of the error, and then clear the error.

MESSAGE – MSG(46)

MSG(46) is used to display a message on a Programming Device connected to

the CPM2B. The message, which can be up to 16 characters long, is displayed

when the instruction’s execution condition is ON.

7-3-3 Non-fatal Errors

PC operation and program execution will continue after one or more of these

errors have occurred. Although PC operation will continue, the cause of the error

should be corrected and the error cleared as soon as possible.

When one of these errors occurs, the POWER and RUN indicators will remain lit

and the ERR indicator will flash.

Message

FAL No.

Meaning and appropriate response

SYS FAIL FAL**

01 to 99 An FAL(06) instruction has been executed in the program. Check the FAL number to

(** is 01 to 99 or 9B.)

determine conditions that would cause execution, correct the cause, and clear the

error.

An error has been detected in the PC Setup. Check flags AR 1300 to AR 1302, and

correct as directed.

AR 1300 ON: An incorrect setting was detected in the PC Setup (DM 6600 to

DM 6614) when power was turned on. Correct the settings in PROGRAM Mode and

turn on the power again.

AR 1301 ON: An incorrect setting was detected in the PC Setup (DM 6615 to

DM 6644) when switching to RUN or MONITOR mode. Correct the settings in

PROGRAM Mode and switch to RUN or MONITOR mode again.

AR 1302 ON: An incorrect setting was detected in the PC Setup (DM 6645 to

DM 6655) during operation. Correct the settings and clear the error.

SCAN TIME OVER

The cycle time has exceeded 100 ms. (SR 25309 will be ON.)

This indicates that the program cycle time is longer than recommended. Reduce cycle

time if possible. (The CPM2B can be set so that this error won’t be detected.)

Battery error

(no message)

If the voltage of the C500-BAT08 backup battery is below the minimum level, the ERR

indicator will flash and SR 25308 will be turned ON.

Replace the battery. (See 7-6 Battery Replacement for details.)

Section 7-3

7-3-4 Fatal Errors

PC operation and program execution will stop and all outputs from the PC will be

turned OFF when any of these errors have occurred. CPM2B operation can’t be

restarted until the PC is turned off and then on again or a Programming Device is

used to switch the PC to PROGRAM mode and clear the fatal error.

All CPU Board indicators will be OFF for the power interruption error. For all

other fatal operating errors, the POWER and ERR indicators will be lit. The RUN

indicator will be OFF.

Message

FALS

No.

Meaning and appropriate response

Power interruption

(no message)

Power has been interrupted for more than 2 ms.
