Application Precautions

• 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.

• When the 24-VDC output (service power supply to the PC) is overloaded or

short-circuited, the voltage may drop and result in the outputs being turned

OFF. 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.

Caution Tighten the screws on the terminal block of the AC Power Supply Unit to the

torque specified in the operation manual. The loose screws may result in burning

or malfunction.

Application Precautions

• Always connect to a class-3 ground (to 100 Ω or less) when installing the Units.

Not connecting to a class-3 ground may result in electric shock.

• Always turn off the power supply to the PC before attempting any of the follow-

ing. Not turning off the power supply may result in malfunction or electric

shock.

• Mounting or dismounting I/O Units, CPU Units, or any other Units.

• Assembling the Units.

• 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 or PC Units. Always heed these pre-

cautions.

• 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 Unit. If power supply for the I/O circuits

comes ON before power supply for the Unit, 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 Unit 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 and frequency 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 Units in excess of the rated input voltage.

Excess voltages may result in burning.

• Do not apply voltages or connect loads to the Output Units in excess of the

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

• Disconnect the functional ground terminal when performing withstand voltage

tests. Not disconnecting the functional ground terminal may result in burning.

• Install the Unit properly as specified in the operation manual. Improper installa-

tion of the Unit may result in malfunction.

• 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.

• Be sure to attach the supplied labels when wiring in order to prevent wiring cut-

tings from entering in the Unit.

• Remove the label after the completion of wiring to ensure proper heat dissipa-

tion. Leaving the label attached may result in malfunction.

• Use crimp terminals for wiring. Do not connect bare stranded wires directly to

terminals. Connection of bare stranded wires may result in burning.

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

ing may result in burning.

Application Precautions

• 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.

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

Unit. 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.

• Changing the operating mode of the PC.

• Force-setting/force-resetting any bit in memory.

• Changing the present value of any word or any set value in memory.

• Resume operation only after transferring to the new CPU Unit the contents of

the DM and HR Areas required for resuming operation. Not doing so may result

in an unexpected operation.

• Do not pull on the cables or bend the cables beyond their natural limit. Doing

either of these may break the cables.

• Do not place objects on top of the cables. Doing so may break the cables.

• When replacing parts, be sure to confirm that the rating of a new part is correct.

Not doing so may result in malfunction or burning.

• Before touching the Unit, be sure to first touch a grounded metallic object in

order to discharge any static built-up. Not doing so may result in malfunction or

damage.

• Do not touch the Expansion I/O Unit Connecting Cable while the power is

being supplied in order to prevent any malfunction due to static electricity.

• When using a thermocouple-input type Temperature Sensor Unit, observe the

following precautions:

• Do not remove the cold junction compensator attached at the time of deliv-

ery. If the cold junction compensator is removed the Unit will not be able to

measure temperatures correctly.

• Each of the input circuits is calibrated with the cold junction compensator

attached to the Unit. If the Unit is used with the cold junction compensator

from other Units, the Unit will not be able to measure temperatures cor-

rectly.

• Do not touch the cold junction compensator. Doing so may result in incor-

rect temperature measurement.

Caution Always clear memory before beginning to program the CPM1A. Although

memory is cleared before the CPU Unit is shipped (except for bits with specific

functions), AR 1314, which turns ON when the internal capacitor cannot back up

memory, may have turned ON during shipment.

Caution If the CPM1A will be turned off for periods exceeding the data backup period of

the internal capacitor, design the system so that it will not be influenced if data in

the DM, HR, and CNT areas is cleared when power is turned off.

Caution Either switch the CPM1A to RUN or MONITOR mode, or turn off and on power to

the CPM1A after changing from a Programming Device any data that is backed

up in flash memory. This data includes the user program, read-only DM area

(DM 6144 to DM 6599), and the PC Setup (DM 6600 to DM 6655).

Application Precautions

• The user program and memory area data in the CPM1A are backed up either

by an internal capacitor or in flash memory as shown in the following table.

Backup method

Data

Internal capacitor

Read/write DM area (DM 0000 to DM 0999, DM 1022, and

DM 1023)

Error log area (DM 1000 to DM 1021)

HR area (HR 00 to HR 19)

Counter area (CNT 000 to CNT 127)

User program

Flash memory

Read-only DM area (DM 6144 to DM 6599)

PC Setup (DM 6600 to DM 6655)

Note 1. The IR, TR, LR, and timer areas are not normally backed up when power is

turned off and all contents will be cleared the next time power is turned on.

(The PC Setup setting in DM 6601 can be used to back up this data. Refer to

details on the PC Setup later in this manual for details.)

2. The bits in the AR and SR areas have special functions and are set accord-

ing to these functions when power is turned on.

• The capacitor backup time depends on the ambient temperature, as shown in

the following graph. The backup time, however, assumes that the capacitor is

fully charged, which requires that power be supplied to the CPU Unit continu-

ously for at least 15 minutes.

Ambient temperature (_ C)

If the power remains off for a period exceeding the data backup period,

AR 1314 will turn ON to indicate that the capacitor can no longer back up data

and the data backed up by the capacitor will be cleared. AR 1314 will remain

ON unless it is turned OFF using I/O monitor operations, using memory clear

operations, or from the user program.

If desired, the PC Setup setting in DM 6604 can be set to create a fatal error

and thus stop the system when AR 1314 goes ON.

• The data stored in flash memory will not be lost even if power remains off for a

period exceeding the data backup period, because the data stored in flash

memory will be read to the CPU Unit when the CPM1A is turned on.

• If the power is turned off without changing the mode from PROGRAM mode to

RUN or MONITOR mode after having made changes in the data that is backed

up in flash memory, the changes will not be written to flash memory. If the

power is then left off for more than 20 days (at 25_ C), the changes (i.e., the

contents of the RAM) will be erased and the data values will become unde-

fined.

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).

6-3

Conformance to EC Directives

The CPM1A PCs (transistor output models) comply with EC Directives. Relay

output models do not conform to the EC Directives. To ensure that the machine

or device in which the CPM1A PC is used complies with EC directives, the PC

must be installed as follows:

1, 2, 3...

1. The CPM1A 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. CPM1A 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.

4. The CPM1A with relay output does not conform to the EC Directives. For

devices for use in the EC, use the CPM1, which meets the CE marking

requirements. Further information is available at any of the OMRON offices

or OMRON sales representatives listed on the inside back cover of this

CPM1A Features and Functions

Section 1-1

1-1 CPM1A Features and Functions

1-1-1 CPM1A Features

One-piece Construction

The CPM1A CPU Units feature a one-piece construction including 10, 20, 30, or

40 built-in I/O terminals. The following three model groups are available: relay

output models, sink-type transistor output models, and source-type transistor

output models.

CPM1A-10CDR-j/10CDT-D/10CDT1-D CPM1A-20CDR-j/20CDT-D/20CDT1-D

(10 I/O terminals)

(20 I/O terminals)

CPM1A-30CDR-j/30CDT-D/30CDT1-D CPM1A-40CDR-j/40CDT-D/40CDT1-D

(30 I/O terminals) (40 I/O terminals)

Extra I/O Capacity

Up to three Expansion I/O Units can be connected to a CPM1A-30CDR-j/

30CDT-D/30CDT1-D or CPM1A-40CDR-j/40CDT-D/40CDT1-D CPU Unit to

add an extra 8 or 20 I/O points for each, for a maximum of up to 100 I/O points.

Input Filter Function

The CPM1A is equipped with a filter function to prevent incorrect operation

caused by chatter or noise in the input signal. The user can select an input time

constant of 1 ms, 2 ms, 4 ms, 8 ms, 16 ms, 32 ms, 64 ms, or 128 ms.

Low-maintenance Design

Input Interrupts

Flash memory provides memory backup without a battery.

The CPM1A-10CDR-j/10CDT-D/10CDT1-D CPU Units can handle 2 interrupt

inputs; the CPM1A-20CDR-j/20CDT-D/20CDT1-D, CPM1A-30CDR-j/

30CDT-D/30CDT1-D, and CPM1A-40CDR-j/40CDT-D/40CDT1-D CPU Units

can handle 4 interrupt inputs. In addition to normal input interrupts, the CPM1A

has a counter mode that counts high-speed input signals and triggers interrupts

at fixed count multiples.

Quick-response Inputs

Interval Timer

Quick-response inputs can detect input signals with a pulse width as short as

0.2 ms regardless of their timing during the PC cycle. Quick-response inputs

and interrupt inputs use the same input terminals.

CPM1A PCs have a high-speed interval timer which can be set from 0.5 ms to

319,968 ms. The timer can be set to trigger a single interrupt (one-shot mode) or

repeat scheduled interrupts (scheduled interrupt mode).

High-speed Counter

CPM1A PCs have a high-speed counter that can be used in incremental mode

or up/down mode. The high-speed counter can be combined with input inter-

rupts to perform target value control or zone comparison control that isn’t

affected by the PC’s cycle time.

Pulse Output Function

Analog Setting Function

The CPM1A transistor output models have an output function capable of output-

ting a pulse of 20 Hz to 2 kHz (single-phase output).

The CPM1A PCs have 2 analog volume controls that can be used to make

manual analog settings.

CPM1A Features and Functions

Section 1-1

Analog I/O Units

Up to 3 Analog I/O Units can be connected to provide analog inputs and outputs.

Each Unit provides 2 analog inputs and 1 analog output, so a maximum of 6 ana-

log inputs and 3 analog outputs can be achieved by connecting 3 Analog I/O

Units.

The analog input range can be set to 0 to 10 VDC, 1 to 5 VDC, or 4 to 20 mA with a

resolution of 1/256. (The open-circuit detection function can be used with the 1 to

5 VDC and 4 to 20 mA settings.)

The analog output range can be set to 0 to 10 VDC, –10 to 10 VDC, or 4 to 20 mA

with a resolution of 1/256.

Temperature Sensor

Units

A Temperature Sensor Unit can be connected to provide up to 6 inputs for tem-

perature input from sensors, such as thermocouples or platinum resistance

thermometers.

Host Link Communications The CPM1A PCs are compatible with the Host Link, which allows communica-

tions with personal computers. The CPM1A using the Host Link can also com-

municate with Programmable Terminal using host link commands.

An RS-232C Adapter is used for 1:1 communications and an RS-422 Adapter is

used for 1:N communications.

One-to-one PC Link

A data link can be created with a data area in another CPM1A, CQM1, CPM1,

SRM1 or C200HS or C200HX/HE/HG PC. An RS-232C Adapter is used to make

the 1:1 connection.

NT Link Communications

High-speed operations can be achieved by providing a direct access by con-

necting the CPM1A to the OMRON Programmable Terminal through the NT Link

Interface. An RS-232C Adapter is used for this connection.

CompoBus/S I/O Link

Units

Up to 3 CompoBus/S I/O Link Units can be connected to make the CPM1A a

Slave Device in a CompoBus/S Network. The I/O Link Unit has 8 input bits (inter-

nal) and 8 output bits (internal).

The CompoBus/S Network provides distributed CPU control based on a “PC +

compact PC” configuration, which is an improvement on the earlier distributed

I/O control based on a “PC + remote I/O” configuration. The distributed CPU

control makes equipment modular, so designs can be standardized, special

needs can be addressed, and modules can be replaced easily in the event of a

breakdown.

Standard Peripheral Devices The CPM1A uses the same Programming Consoles and SYSMAC Support

Software (SSS) as the C200H/HS, C200HX/HE/HG, CPM1, SRM1, and CQM1

PCs.

Programming is Possible

Input Filter Function

The input time constant for the CPM1A’s external inputs can be set to 1, 2, 4, 8,

16, 32, 64, or 128 ms. Increasing the input time constant can reduce the effects

of chatter or noise in the input signal.

CPM1A Features and Functions

Section 1-1

Input Interrupts

The CPM1A-10CDR-j/10CDT-D/10CDT1-D PCs have 2 interrupt input termi-

nals and the CPM1A-20CDR-j/20CDT-D/20CDT1-D, CPM1A-30CDR-j/

30CDT-D/30CDT1-D, and CPM1A-40CDR-j/40CDT-D/40CDT1-D PCs have

4 interrupt input terminals. There are two modes for input interrupts: input inter-

rupt mode and counter mode.

1, 2, 3...

1. When an interrupt occurs in Input Interrupt Mode, the main program is inter-

rupted and the interrupt program is executed immediately, regardless of the

cycle time.

2. In Counter Mode, external input signals are counted at high speed (up to

1 kHz) and an interrupt is generated each time the count reaches the set

value. When an interrupt occurs, the main program is interrupted and the

interrupt program is executed. The set value can be set from 0 to 65,535.

The following diagram shows the program execution when an interrupt occurs.

Note When not using as interrupt input terminals, the input bits IR 00003 to IR 00006

can be used as normal input terminals.

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.

30CDR-j/30CDT-D/30CDT1-D and CPM1A-40CDR-j/40CDT-D/40CDT1-D

PCs have 4 quick-response input terminals. (The same terminals are used for

quick-response inputs and interrupt inputs.)

Quick-response inputs have an internal buffer, so input signals shorter than one

cycle can be detected.

A CompoBus/S I/O Link can be used to create an I/O link (remote I/O) of 8 input

points and 8 output points with a CompoBus/S Master Unit or SRM1 PC. The

connection is made through a CompoBus/S I/O Link Unit.

From the standpoint of the CPM1A CPU Unit, the area allocated to the Compo-

Bus/S I/O Link Unit can be treated just like the area allocated to an Expansion I/O

Unit. The difference is that the bits are not actual I/O points, but I/O bits in the

Master Unit.

temperature. See the graph on the following page for details.

Note 1. Use TIM 000 to TIM 003 when creating a timer using the high-speed timer

instruction to perform interrupt processing.

2. The input interrupt response time is 0.3 ms max.

Memory Backup

The user program and memory area data in the CPM1A are backed up either by

an internal capacitor or in flash memory as shown in the following table.

HR area (HR 00 to HR 19)

Counter area (CNT 000 to CNT 127)

User program

Flash memory

Read-only DM area (DM 6144 to DM 6599)

PC Setup (DM 6600 to DM 6655)

Note 1. The IR, TR, LR, and timer areas are not normally backed up when power is

turned off and all contents will be cleared the next time power is turned on.

(The PC Setup setting in DM 6601 can be used to back up this data. Refer to

details on the PC Setup later in this manual for details.)

2. The bits in the AR and SR areas have special functions and are set accord-

ing to these functions when power is turned on.

The capacitor backup time depends on the ambient temperature, as shown in

the following graph. The backup time, however, assumes that the capacitor is

fully charged, which requires that power be supplied to the CPU Unit continu-

ously for at least 15 minutes.

Ambient temperature (_ C)

If the power remains off for a period exceeding the data backup period,

AR 1314 will turn ON to indicate that the capacitor can no longer back up data

and the data backed up by the capacitor will be cleared. AR 1314 will remain

ON unless it is turned OFF using I/O monitor operations, using memory clear

operations, or from the user program.

If desired, the PC Setup setting in DM 6604 can be set to create a fatal error

and thus stop the system when AR 1314 goes ON.

The data stored in flash memory will not be lost even if power remains off for a

period exceeding the data backup period, because the data stored in flash

memory will be read to the CPU Unit when the CPM1A is turned on.

If the power is turned off without changing the mode from PROGRAM mode to

RUN or MONITOR mode after having made changes in the data that is backed

up in flash memory, the changes will not be written to flash memory. If the power

is then left off for more than 20 days (at 25_ C), the changes (i.e., the contents of

the RAM) will be erased and the data values will become undefined.

Either switch the CPM1A to RUN or MONITOR mode, or turn off and on power to

the CPM1A after changing from a Programming Device any data that is backed

Design Precautions

Section 3-1

3-1 Design Precautions

Observe the following precautions when designing a system incorporating a

CPM1A PC.

3-1-1 Power Supply Wiring

Separate the power supply wiring from the control system, CPM1A 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 protectors and fuses.

3-1-2 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.

Construct an external interlock circuit if CPM1A outputs are used to perform

reciprocal operations such as controlling the forward and reverse operation of a

motor or if incorrect PC operation could cause accidents or mechanical damage.

Also, construct an external limit circuit to prevent run-away movement in sys-

tems such as position control.

The following diagram shows an example of an interlock circuit.

Interlock Circuit

01005

01006

CPM1A

MC1

In the interlock circuit above, MC1 and MC2 can’t be ON at the same time even if

CPM1A outputs 01005 and 01006 are both ON (an incorrect PC operation).

3-1-3 Power Supply Voltage

Caution Use the power supply voltages indicated in Section 2 Unit Specifications and

Components. Failure to adhere to the specifications may result in fire. In places

where power supply conditions are poor, take steps to ensure that power is sup-

plied at the rated voltage. Be sure to adhere to safety precautions, such as pro-

viding breakers to prevent short circuits in external wiring. When conducting any

of the following operations, turn OFF the power to the PC. Electric shock, prod-

uct damage and malfunction may result.

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

• Assembling Units

• Connecting cables and wiring.

3-1-4 CPM1A Power Interruptions

Supply Voltage Drop

When the supply voltage falls below 85% of the rated value, the PC will stop and

the outputs will go OFF.

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

Selecting an Installation Site

Section 3-2

Momentary Power Failure Detection

A momentary power failure lasting less than 10 ms with an AC power supply and

2 ms with a DC power supply is not detected and the CPU Unit continues to oper-

ate.

A momentary power failure lasting longer than 10 ms with an AC power supply

and 2 ms with a DC power supply may or may not be detected in an uncertain

area.

When a momentary power failure is detected, the CPU Unit stops operating and

the output goes OFF.

Automatic Restart

When the supply voltage recovers to a value higher than 85% of the rated value,

operations resumes automatically.

Under

Over

10 ms (2 ms)

Duration of power interrupt

(Below 85% of rated voltage)

Normal operation

Operation may stop.

All outputs go OFF when

operations stop.

Note The CPM1A may repeat stop/start operations if the supply voltage of less than

85% of the rated value gradually goes up or down.

If this affects the equipment, etc., provide a protection circuit which shuts off the

output if the supply voltage is not above the rated value.

Time Up to the Start of Operation

The time from when the power supply is turned on to when the operation starts

varies depending on the operation conditions such as power supply voltage,

configuration, ambient temperature, etc. The minimum time is approximately

300 ms.

3-2 Selecting an Installation Site

The CPM1A is resistant to harsh conditions and highly reliable, but installing the

PC in a favorable site will maximize its reliability and operating lifetime.

Caution Be sure to install the CPM1A correctly, as outlined in this manual. Failure to do so

may result in Unit malfunction.

3-2-1 Installation Site Conditions

Note Do not install the CPM1A under any of the following conditions.

• Locations subject to direct sunlight.

• Locations subject to a temperature below 0°C or over 55°C.

• Locations subject to a humidity below 10% or over 90%.

• Locations subject to condensation as the result of severe changes in tempera-

ture.

• Locations subject to corrosive or flammable gases.

• Locations subject to dust (especially iron dust) or salts.

• Locations subject to shock or vibration.

• Locations subject to exposure to water, oil, or chemicals.

Be sure that the conditions at the installation site conform to the CPM1A’s gen-

eral specifications. Refer to 2-1-1 General Specifications for details.

3-2-2 Panel/Cabinet Installation

Consider PC operation, maintenance, and surrounding conditions when instal-

ling the CPM1A in a panel or cabinet.

Overheating

The operating temperature range for the CPM1A is 0_ C to 55_ C. Be sure that

there is adequate ventilation for cooling.

• Allow enough space for air circulation.

• Do not install the CPM1A above equipment that generates a large amount of

heat, such as heaters, transformers, or large resistors.

• Install a cooling fan or system when the ambient temperature exceeds 55_ C.

Caution Disconnect the functional earth terminal when performing withstand voltage

tests. Not disconnecting the functional earth terminal may result in burning.

Crimp Connectors

Caution Always use crimp connectors for the CPM1A’s power lines and I/O lines or else

use a solid wire (instead of a stranded wire). Do not connect bare stranded wires

directly to terminals. Bare stranded wires connected directly to the terminal can

cause a fire.

Use M3 terminal screws and tighten the screws securely (0.5 N S m).

100- to 240-VAC Power

Supply

Wire a separate circuit for the CPM1A’s power supply circuit so that there isn’t a

voltage drop from the inrush current that flows when other equipment is turned

on.

When several CPM1A PCs are being used, it is recommended to wire the PCs

on separate circuits to prevent a voltage drop from the inrush current or incorrect

operation of the circuit breaker.

Use twisted power supply wires to prevent noise from the power supply lines.

Adding a 1:1 isolating transformer reduces electrical noise even further.

Considering the possibility of voltage drops and the allowable current, be sure to

use thick power lines.

Twist the wires. The cross-sectional area

of each wire must be 1.25 mm min.

Note 1. Before connecting the power supply, make sure that the CPU Unit requires

an AC power supply and not a DC power supply. The CPU Unit’s internal

circuitry will be damaged if AC power is mistakenly supplied to a CPU Unit

that requires a DC power supply.

2. The power supply input terminals are at the top of the CPU Unit; the termi-

nals at the bottom of the CPU Unit output 24-VDC power for external de-

vices. The CPU Unit’s internal circuitry will be damaged if AC power is mis-

takenly supplied to a CPU Unit’s power supply output terminals.

Crimp Connectors

Caution Always use crimp connectors for the CPM1A’s power lines. Do not connect bare

stranded wires directly to terminals. Bare stranded wires connected directly to

the terminal can cause a fire.

Output Wiring 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 (0.5 to

1.0 A) in each output circuit.

Polarity of Power Supply for the Load

Double-check the polarity of the DC power supply for the load before wiring the

transistor output. If the polarity of the power supply is reversely connected, the

load will malfunction and internal components may be damaged.

Section 3-4

3-4-10 CompoBus/S I/O Link Connections

A CompoBus/S I/O Link can be used to create an I/O link (remote I/O) of 8 input

points and 8 output points with a CompoBus/S Master Unit or SRM1 PC. The

connection is made through a CompoBus/S I/O Link Unit.

From the standpoint of the CPM1A CPU Unit, the area allocated to the Compo-

Bus/S I/O Link Unit can be treated just like the area allocated to an Expansion I/O

Unit. The difference is that the bits are not actual I/O points, but I/O bits in the

Master Unit.

Support Software Capabilities

Section 4-1

4-1 Support Software Capabilities

The SSS is a complete programming and control package designed for C-series

and CVM1 PCs. It provides not only programming capabilities, but also

advanced debugging, monitoring, and program/data management. The follow-

ing tables provide only a brief introduction to the capabilities of the SSS. For fur-

ther information and actual operating procedures, please refer to the SYSMAC

Support Software Operation Manuals: Basics and C-series.

CPM1A programming can be performed with any version of the SSS.

In addition, the SYSMAC-CPT can be used for programming the CPM1A. Refer

to the SYSMAC-CPT Support Software Quick Start Guide (W332) and User

Manual (W333) for operation procedures. When programming the CPM1A

using the SYSMAC-CPT, be sure to set the “PC model” on the Support Software

to “CPM1 (CPM1A).”

Operations for the WS02-CXPC1-E CX-Programmer are provided in the

WS02-CXPC1-E CX-Programmer User Manual (W361) and the CX-Server

User Manual (W362).

4-1-1 SSS System Setup

Set the PC Model to “CQM1” and the PC Interface to “PERIPHERAL.” Follow the

directions in the SSS operating manuals for other System Setup settings.

PC Model

If the CPM1A PC doesn’t appear as an option in the SSS’s System Setup, set the

PC Model to “CQM1.” The CPM1A is compatible with the CQM1.

PC Interface

Set the PC Interface to the Peripheral Device Port by selecting “PERIPHERAL”

from the submenu. After selecting the Peripheral Device Port, set the commu-

nications baud rate to 9,600 baud.

4-1-2 CPM1A Restrictions and Precautions

When programming the CPM1A, set the PC Model on the SSS to “CQM1.” Heed

the following restrictions when programming the CPM1A.

Programming Check

Since the data area of the CQM1 is larger than that of the CPM1A, some parts of

the area cannot be checked as the CPM1A PC. Pay careful attention to the

usable data area when programming.

Note If a program that contains addresses not supported by the CPM1A are trans-

ferred to the CPM1A, a memory error will occur when operation is begun and

AR 1308 will turn ON. Refer to the Programming Manual (W353) for differences

in memory areas.

Memory Usage

Since the memory of the the CQM1 is larger than that of the CPM1A, the dis-

played available memory capacity is larger than the actual available memory

capacity. Pay careful attention to the actual available memory capacity when

programming.

Expansion Instructions

When a program is transferred after changing the assignment of function codes

for the 18 expansion instructions, a message to “Turn on the DIP switch of the

PC and execute again” is displayed. Change the assignment of the function

codes for the expansion instructions to the default settings before programming.

The default settings for the CQM1 are as shown in the following table.

4-2-4 Preparation for Operation

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 Unit’s peripheral port. See

4-2-3 Connecting the Programming Console for details.

(The CPU Unit’s Communications Switch setting has no effect on commu-

nications with the Programming Console.)

3. Set the mode switch to PROGRAM mode.

4. Turn ON the PC.

5. Enter the password. See 4-2-5 Entering the Password for details.

6. Clear (All Clear) the PC’s memory. See 4-3-2 Clearing Memory for details.

7. Read and clear all errors and messages. See 4-3-3 Reading/Clearing Error

Messages for details.

8. Start programming.

4-2-5 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.

Using a Programming Console

Section 4-2

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.

Initial System Checks and Test Run Procedure

Section 5-1

5-1 Initial System Checks and Test Run Procedure

5-1-1 Initial System Checks

Note Check the following items after setting up and wiring the CPM1A. Be sure to

check the wiring and connections before performing 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 connectors or wires?

Refer to 3-4 Wiring and Connections for details.

Are the cables all connected correctly and locked?

Refer to 3-4 Wiring and Connections for details.

Has the dustproof label been removed?

Connecting cables

Dustproof label

Note 1. Always clear memory before beginning to program the CPM1A. Although

memory is cleared before the CPU Unit is shipped (except for bits with spe-

cific functions), AR 1314, which turns ON when the internal capacitor cannot

back up memory, may have turned ON during shipment.

2. If the CPM1A will be turned off for periods exceeding the data backup period

of the internal capacitor, design the system so that it will not be influenced if

data in the DM, HR, and CNT areas is cleared when power is turned off.

3. Either switch the CPM1A to RUN or MONITOR mode, or turn off and on

power to the CPM1A after changing from a Programming Device any data

that is backed up in flash memory. This data includes the user program,

read-only DM area (DM 6144 to DM 6599), and the PC Setup (DM 6600 to

DM 6655).

5-1-2 CPM1A Test Run Procedure

1, 2, 3...

1. Power Supply Application

a) Check the CPM1A’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.

d) Use a Peripheral Device to set the CPM1A to PROGRAM mode.

2. I/O Wiring Checks

a) With the CPM1A in PROGRAM mode, check the output wiring by turning

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

Refer to 4-3-23 Force Set, Reset for details.

b) Check the input wiring with the CPM1A’s input indicators or a Peripheral

Device’s monitor operations.

3. Test Run

a) Use a Peripheral Device to set the CPM1A 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 Peripheral 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 Peripheral Devices for details on SYSMAC Support

Software or Programming Console operations.

Initial System Checks and Test Run Procedure

Section 5-1

5-1-3 Flash Memory Precautions

Observe the following precautions to protect the flash memory and ensure

proper operation.

1, 2, 3...

1. If the power is turned off without changing the mode after having made chan-

ges in the read-only DM area (DM 6144 through DM 6599), or PC Setup (DM

6600 through DM 6655), the contents of changes will not be written to flash

memory. Therefore, if the power is turned off for more than 20 days (at

25_ C), contents of changes (contents of the RAM) will disappear and the

data values will become undefined values. For details, refer to 2-1-2 Char-

acteristics.

The changes can be saved by switching the CPM1A to RUN or MONITOR

mode or turning on the CPM1A soon after the changes are made.

2. When the CPM1A is operated for the first time after changing the program,

the read-only DM area (DM 6144 through DM 6599) or PC Setup (DM 6600

through DM 6655) will take about 600 ms longer than usual. Be sure to take

this one-time startup delay into account.

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

mode, the CPM1A will extend the cycle time for up to 600 ms and interrupts

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. The

CPM1A’s I/O response times may be affected when the online edit operation

is being performed.

The CPM1A Cycle

Section 5-2

5-2 The CPM1A Cycle

The overall flow of CPM1A operation is as shown in the following flowchart. The

CPM1A is initialized internally when the power is turned on. If no errors are

detected, the overseeing processes, program execution, I/O refreshing, and

Peripheral Device servicing are executed consecutively (cyclically). The aver-

age cycle time can be monitor from a Peripheral Device.

Self-diagnosis Functions

Section 5-3

5-3 Self-diagnosis Functions

The CPM1A is equipped with a variety of self-diagnosis functions to help identify

and correct errors that might occur and reduce down time.

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

errors are more serious errors which stop CPM1A operation. Non-fatal errors

are less serious and don’t stop CPM1A operation.

5-3-1 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/ALM 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 Mode. Correct the settings in PROGRAM Mode

and switch to RUN 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

Watchdog timer 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 CPM1A can be set so that this error won’t be detected.)

Communication

Errors (no message)

None

If an error occurs in communications through the peripheral port, the COMM indicator

will be off. Check the connecting cables and restart. Check the error flags in AR 0812

ON.

5-3-2 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. CPM1A operation can’t be

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

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

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

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

indicator will be OFF.

WARNING 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. External

safety measures must be provided to ensure safety in the system. Not providing

proper safety measures may result in serious accidents.

An error has occurred during data transfer between the CPU Unit and Expansion I/O

Unit. Check the Expansion I/O Unit’s connecting cable.

I/O UNIT OVER

Too many I/O Units have been connected. Check the I/O Unit configuration.

SYS FAIL FALS**

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

01 to 99 A FALS(07) instruction has been executed in the program. Check the FALS number to

determine the conditions that caused execution, correct the cause, and clear the error.

The cycle time has exceeded the FALS 9F Cycle Time Monitoring Time (DM 6618).

Check the cycle time and adjust the Cycle Time Monitoring Time if necessary.

5-3-3 Identifying Errors

PC errors can be identified from error messages displayed on the Programming

Console, error flags in the SR or AR areas, and the error code in SR 25300 to

SR 25307.

Error Messages

Error Flags

Error messages generated by the self-diagnosis function can be read from a

Programming Console or host computer running SYSMAC Support Software.

When the self-diagnosis function detects a hardware error, it will turn on the cor-

responding error flags in the SR and AR areas.

Error Code

When an error is detected by the self-diagnosis function, the corresponding

error code is written to SR 25300 to SR 25307. (The error code is an 2-digit hex-

adecimal code.)

5-3-4 User-defined Errors

There are three instructions that the user can use to define his own 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 con-

nected 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/ALM indicator on the CPU Unit will flash. PC operation will con-

tinue.

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. The

same number cannot 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

clear the error using the Programming Console.

Programming Errors

Section 5-5

Three levels of program checking are available. The desired level must be des-

ignated to indicate the type of errors that are to be detected. The following table

provides the error types, displays, and explanations of all syntax errors. Check

level 0 checks for type A, B, and C errors; check level 1, for type A and B errors;

and check level 2, for type A errors only.

Type

Message

?????

Meaning and appropriate response

The program has been damaged, creating a non-existent

function code. Re-enter the program.

CIRCUIT ERR

The number of logic blocks and logic block instructions

does not agree, i.e., either LD or LD NOT has been used

to start a logic block whose execution condition has not

been used by another instruction, or a logic block

instruction has been used that does not have the required

number of logic blocks. Check your program.

OPERAND

ERR

A constant entered for the instruction is not within defined

values. Change the constant so that it lies within the

proper range.

NO END

INSTR

There is no END(01) in the program. Write END(01) at the

final address in the program.

LOCN ERR

An instruction is in the wrong place in the program. Check

instruction requirements and correct the program.

JME UNDEFD

A JME(05) instruction is missing for a JMP(04) instruction.

Correct the jump number or insert the proper JME(05)

instruction.

DUPL

The same jump number or subroutine number has been

used twice. Correct the program so that the same number

is only used once for each.

SBN UNDEFD

STEP ERR

The SBS(91) instruction has been programmed for a

subroutine number that does not exist. Correct the

subroutine number or program the required subroutine.

STEP(08) with a section number and STEP(08) without a

section number have been used incorrectly. Check

STEP(08) programming requirements and correct the

program.

IL-ILC ERR

IL(02) and ILC(03) are not used in pairs. Correct the

program so that each IL(02) has a unique ILC(03).

Although this error message will appear if more than one

IL(02) is used with the same ILC(03), the program will

executed as written. Make sure your program is written as

desired before proceeding.

JMP-JME ERR JMP(04) and JME(05) are not used in pairs. Make sure

your program is written as desired before proceeding.

SBN-RET ERR If the displayed address is that of SBN(92), two different

subroutines have been defined with the same subroutine

number. Change one of the subroutine numbers or delete

one of the subroutines. If the displayed address is that of

RET(93), RET(93) has not been used properly. Check

requirements for RET(93) and correct the program.

COIL DUPL

The same bit is being controlled (i.e., turned ON and/or

OFF) by more than one instruction (e.g., OUT, OUT NOT,

DIFU(13), DIFD(14), KEEP(11), SFT(10)). Although this is

allowed for certain instructions, check instruction

requirements to confirm that the program is correct or

rewrite the program so that each bit is controlled by only

one instruction.

JMP UNDEFD

SBS UNDEFD

JME(05) has been used with no JMP(04) with the same

jump number. Add a JMP(04) with the same number or

delete the JME(05) that is not being used.

A subroutine exists that is not called by SBS(91). Program

a subroutine call in the proper place, or delete the

subroutine if it is not required.
