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 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.)

• 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.
• Double-check all the wiring before turning ON the power supply. Incorrect wir-
ing may result in burning.
• Do not attempt to take any Units apart, to repair any Units, or to modify any
Units in any way.
• Do not apply any impact to the Units.
• Use the cables specified in this manual and in reference manuals. Use crimp
terminals when wiring the terminal block.
• Use a signal wire duct that is separate from the one used for high-tension lines
or power lines.
• Be sure to confirm that the switch settings and wiring are correct before turning
on the power supply.
• 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 the user programs run properly.

Application Precautions
5
Caution The following precautions are necessary to ensure the general safety of the sys-
!
tem. Always heed these precautions.
• Provide double safety mechanisms to handle incorrect signals that can be
generated by broken signal lines or momentary power interruptions.
• Provide external interlock circuits, limit circuits, and other safety circuits in
addition to any provided within the SRM1 to ensure safety.
Caution Be sure to clear the memory before turning on the power supply to the delivered
SRM1. The contents of the Data Memory (DM), Hold Relay (HR), and Counter
(CNT) Areas in the CPU Unit may be cleared and the AR 1314 flag (which turns
ON when the power interruption hold area is not held) may turn ON.
!
!
Caution Apply the SRM1 to a system that is not influenced by any undefined data even if
the data in the DM, HR, or CNT area is cleared when the SRM1 has been turned
off for a period exceeding the data backup period of the internal lithium battery.
If the AR 1414 flag is ON, the data will be held unless it is turned OFF by the I/O
Monitor, instructions, etc.
The system can be stopped by designating DM 6604 in the PC Setup so that a
memory error occurs when the power interruption hold area is not held (with
AR 1314 ON)
• A lithium battery in the CPU Unit is used to back up the counter values and the
contents of the DM area, and HR area. The deterioration of the lithium battery
capacity depends on the ambient temperature. The standard service life is 12
years under an ambient temperature of 40_C when operating 8 hours a day.
If the power remains off for a period exceeding the data backup period, the
contents of the Data Memory (DM), Hold Relay (HR), and Counter (CNT)
Areas in the CPU Unit may be cleared and the AR 1314 flag (which turns ON
when the power interruption hold area is not held) may turn ON.
If the contents of the CPU Unit’s program area are lost, the program stored in
flash memory will be read to the CPU Unit’s program area when the SRM1 is
started up because the contents in the read-only area (DM 6144 through
DM 6599) and PC Setup (DM 6600 through DM 6655) will be written to flash
memory.
• However, if the power is turned off without changing the mode even if changes
are made in the read-only DM area (DM 6144 through DM 6599), or PC Setup
(DM 6600 through DM 6655) using a peripheral device, the contents of
changes will not be written to flash memory. Although the data in these areas is
backed up by the lithium battery, contents of changes will disappear if the ser-
vice life of the lithium battery expires. In this case, programs in the flash
memory will be automatically read into the user program memory.
The changes can be saved by switching the SRM1 to RUN or MONITOR mode
or turning off and restarting the SRM1 soon after the changes are made.

SRM1 Features and Functions
Section 1-1
1-1 SRM1 Features and Functions
1-1-1 Features
The SRM1 is a special CompoBus/S controller that provides remote I/O with
greatly reduced wiring. The SRM1 has no built-in I/O terminals, but it can provide
the same I/O control as earlier PCs through the Slaves (Slave Terminals) that
are used for I/O.
A decentralized I/O system with up to 32 Slaves can be constructed. The system
can have up to 256 I/O points and these I/O points are controlled with the Com-
poBus/S System’s high-speed response time of 1 ms max.
A very reliable and efficiently wired system can be constructed from special
CompoBus/S components such as Analog Terminals (SRM1-C0j-V2 only),
Remote Terminals, Sensor Terminals, Communications Cables, Connectors,
and Terminators.
In SRM1-C0j-V2, the CompoBus/S system can be set to operate in long-dis-
tance communications mode in addition to the previous high-speed commu-
nications mode. This allows a main line length of up to 500 m so that I/O devices
can be controlled from some distance away. The SRM1-C0j-V2 can also pro-
cess analog data as well as digital I/O.
The SRM1’s compact design allows for a smaller and thinner control panel.
The SRM1 is equipped with a program capacity of 4K words and a DM capacity
of 2K words.
There are two SRM1(-V2) models available: the SRM1-C02-V2, which is
equipped with an RS-232C port and communications functions, and the very
cost-effective SRM1-C01-V2, which is not equipped with an RS-232C port.
1-1-2 Functions
Interval Timer Function
The SRM1 is equipped with an interval timer which can be set from 0.5 ms to
319,968 ms in units of 0.1 ms. The timer can be set to trigger a single interrupt
(one-shot mode) or repeat scheduled interrupts (scheduled interrupt mode).
(The interrupts pause execution of the main program while an interrupt program
is executed.)
Low-maintenance Design
Communications
Memory can be backed up without a battery by using flash memory.
The SRM1 can communicate with PCs or other devices via Host Link, 1:1 NT
Link, 1:N NT Link, 1:1 PC Link, or RS-232C communications.

Programming Using the
PT
Programming is possible through the PT (Programmable Terminal) screen us-
ing an OMRON PT that contains Programming Console functions. (This applies
only to the SRM1-C02-V1 and SRM1-C02-V2.)
Standard Peripheral Devices The SRM1 uses the same Programming Consoles, CX-Programmer, SYSMAC-
CPT, and SYSMAC Support Software (SSS) as the Mini H-type, CQM1,
CPM1/CPM1A, and CPM2A/CPM2C PCs.

Peripheral Devices
The SRM1 can use a Programming Console or a personal computer running
CX-Programmer, SYSMAC Support Software (SSS), or SYSMAC-CPT as a Pe-
ripheral Device.
Programming Console
Programming Consoles are compact Peripheral Devices that support basic
functions such as writing ladder programs and monitoring SRM1 operation.
They are useful for onsite operations.
Refer to Section 4 Using a Programming Console for details on Programming
Console operations.
SYSMAC Support Software (SSS), SYSMAC-CPT, and CX-Programmer
In addition to the basic Programming Console operations, the CX-Programmer,
SYSMAC-CPT, and SSS can be used to edit ladder programs offline, save pro-
grams to disk, and perform high-level monitoring; the CX-Programmer, SYS-
MAC-CPT and SSS functions allow the user to design more efficient ladder pro-
grams. Refer to the manuals listed on the About this Manual page for details on
using them.
SYSMAC Support Software (SSS)
When using the SSS, set the PC model to the “CQM1” and observe the following
restrictions.
• Addresses will be checked according to the CQM1 address ranges, which are
wider than the SRM1 address ranges. Be sure to use only the allowable ad-
dresses.
• The CQM1 has a larger memory than the SRM1 and the amount of memory
available display will not be correct. Allow for the difference between capaci-
ties.

Procedures From System Design to Test Operation
Section 1-3
• Instructions will be displayed that are not supported by the SRM1. Do not use
these instructions.
CX-Programmer and SYSMAC-CPT
The following instructions cannot be programmed when using the CX-Program-
mer or SYSMAC-CPT. Errors will occur if an attempt is made to transfer them
from the PC to the computer: SCL(66)/@SCL(66), ZCP, NEG/@NEG, and PID.
Host Computers, PTs, and
PCs
An SRM1(-V2) can be connected an IBM PC/AT or compatible computer or OM-
RON PT through an RS-232C Adapter (CPM1-CIF01) mounted to the SRM1’s
peripheral port. (Use Host Link mode when connecting a PT through an
RS-232C Adapter.)
The RS-232C port on an SRM1-C02-V2 can be used to connect directly to an
IBM PC/AT or compatible computer, OMRON PT, or PC (C200HX/HG/HE,
C200HS, CQM1, CPM1, CPM1A, CPM2A, or CPM2C). (Use Host Link mode or
NT Link mode when connecting a PT directly.)

1-4 I/O and Data Area Allocations
1-4-1 I/O Allocations
The input bits of SRM1 words 000 to 007, and the output bits of words 010 to 017,
are allocated to the CompoBus/S Slave. These allocations are shown in the fol-
lowing table.

IN0 to IN15 are Input Slave node numbers, and OUT0 to OUT15 are Output
Slave node numbers.
If the maximum number of CompoBus/S devices is set to 16, then IN8 to IN15
and OUT8 to OUT15 can be used as work bits.
Words IR 008, IR 009, IR 018, and IR 019 can be used as work words.
The bits for two node number are allocated to 16-point Slaves so that all bits are
in the same word. If an even node address is set, the node address that is set
and the next node address following it will be used. For example, if node address
6 is set for a 16-point Output Slave, bits for node addresses OUT6 and OUT7 will
be used. If an odd node address is set, the node address that is set and the pre-
vious node address will be used. For example, if node address 3 is set for a
16-point Output Slave, bits for node addresses OUT2 and OUT3 will be used.
All of the bits for one node address are allocated to a 4-point Slave. If an even
numbered node address is set, bits 00 to 03 are used and bits 04 to 07 are not
used. If an odd numbered node address is set, bits 8 to 11 are used and bits 12 to
15 are not used.

Specifications
Section 2-1
Backup Time vs. Temperature A lithium battery in the CPU Unit is used to back up the contents in the user pro-
gram area, the READ/WRITE area in the Data Memory (DM), Hold Relay (HR),
the Auxiliary Memory Relay (AR), and in the data area of the Counter (CNT). The
deterioration of the lithium battery capacity depends on the ambient tempera-
ture. The standard service life is 12 years under an ambient temperature of 40_C
when operating 8 hours a day.
If the power supply is interrupted after the lithium battery capacity has deterio-
rated, the contents in the user program area, the READ/WRITE area in the Data
Memory (DM), Hold Relay (HR), Auxiliary Memory Relay (AR), and in the data
area of the Counter (CNT) may be lost. Even if the contents of the CPU Unit’s
program area are lost, however, the user program and DM read-only contents
(including the one in the PC Setup area) stored in flash memory will be read to
the CPU Unit’s user program area when the SRM1 is next started up.

System Design
Section 3-1
3-1 System Design
Take the points covered in this section into consideration when designing the
system.
3-1-1 Power Supply Wiring
Separate the power supply wiring from the control system, SRM1 system, and
DC I/O system wiring.
3-1-2 Interlock and Limit Circuits
Construct an external interlock circuit if SRM1 outputs are used to perform recip-
rocal operations such as controlling the forward and reverse operation of a mo-
tor or if incorrect SRM1 operation could cause accidents or mechanical damage.
Also, construct an external limit circuit to prevent run-away movement in opera-
tions such as position control.
The following diagram shows an example of an interlock circuit.
CompoBus/S transmission path
SRM1
Interlock Circuit
MC2
01005
MC1

MC2
In the interlock circuit above, MC1 and MC2 cannot be ON at the same time even
if SRM1 outputs 01005 and 01006 are both ON at the same time (an incorrect
operation).
3-1-3 Power Supply Sequence
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
500 ms and the maximum is approximately 1.1 s.
Momentary Power Failure Detection
A momentary power failure (i.e., a voltage drop to less than 85% of the rated volt-
age) lasting less than 2 ms is not detected and the SRM1 continues to operate.
A momentary power failure lasting longer than 2 ms may cause the SRM1 to
stop operation. If this occurs, operation will be automatically resumed when the
rated voltage again rises above 85%.
Note The SRM1 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.
The output status of Slaves when the SRM1 is stopped can be set on the Slave
side either to have the ON/OFF status directly prior to the stop retained or to
have all outputs turned OFF.

Selecting an Installation Site
Section 3-2
3-2 Selecting an Installation Site
The SRM1 is resistant to harsh conditions and highly reliable, but installing it in a
favorable site will maximize its reliability and operating lifetime.
3-2-1 Installation Site Conditions
Avoid installing the SRM1 in a site with any of the following conditions.
• Where the SRM1 is exposed to direct sunlight.
• Where the ambient temperature is below 0°C or over 55°C.
• Where the SRM1 may be affected by condensation due to radical temperature
changes.
• Where the ambient humidity is below 10% or over 90%.
• Where there is any corrosive or inflammable gas.
• Where there is excessive dust, saline air, or metal powder.
• Where the SRM1 is affected by vibration or shock.
• Where any water, oil, or chemical may splash on the SRM1.
Be sure that the conditions at the installation site conform to the SRM1’s general
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 SRM1 in a panel or cabinet.
Overheating
The operating temperature range for the SRM1 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 SRM1 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.
Control panel
Fan
SRM1
Air vent
Electrical Noise
Power lines and high-voltage equipment can cause electrical noise in the PC.
• Do not install the SRM1 in a panel or cabinet with high-voltage equipment.
• Allow at least 200 mm between the SRM1 and nearby power lines.

• Provide a clear path to the SRM1 for operation and maintenance. High-voltage
equipment or power lines could be dangerous if they are in the way during rou-
tine operations.
• The SRM1 will be easiest to access if the panel or cabinet is installed about 3 to
5 feet off of the floor.
3-3 Installing the SRM1

4-1 Basic Operations
This section provides information on connecting and using a Programming Con-
sole. Refer to 5-5 Programming Console Operation Errors for details on errors
that might occur during Programming Console operations.
4-1-1 Compatible Programming Consoles
There are two Programming Consoles that can be used with the SRM1: the
CQM1-PRO01-E and the C200H-PRO27-E. The key functions for these Pro-
gramming Consoles are identical.
Press and hold the Shift Key to input a letter shown in the upper-left corner of the
key or the upper function of a key that has two functions. For example, the
CQM1-PRO01-E’s AR/HR key can specify either the AR or HR Area; press and
release the Shift Key and then press the AR/HR Key to specify the AR Area.

The SRM1 program isn’t executed in PROGRAM mode. Use PROGRAM mode
to create and edit the program, clear memory, or check the program for errors.
The SRM1 program is executed in MONITOR mode and I/O is processed just as
it is in RUN mode. Use MONITOR mode when testing the system by monitoring
the SRM1’s operating status, force-setting and resetting I/O bits, changing the
SV/PV of timers and counters, etc.
RUN Mode
This is the SRM1’s normal operating mode. The SRM1’s operating status can be
monitored from a Peripheral Device, but bits can’t be force-set/force-reset and
the SV/PV of timers and counters can’t be changed.
Caution Be sure to check the system thoroughly before executing the SRM1 program to
!
prevent any accidents that might occur when the program is first started.

Startup Procedure
Section 5-1
f) Use the Programming Console to set the SRM1 to PROGRAM mode.
g) Use the Programming Console to set the maximum number of Slaves
(bits 00 to 03 of DM 6603) and the CompoBus/S communications mode
(bits 04 to 07 of DM 6603). (The SRM1’s power must be turned OFF and
then ON again to enable new settings in DM 6603.)
h) Check that the “SD” and “RD” indicators light.
2. I/O Wiring Checks
a) With the SRM1 in PROGRAM mode, check the output wiring by turning
on the output bits with the force set and force reset operations.
Refer to 4-2-25 Force Set, Reset for details.
b) Check the input wiring with the SRM1’s input indicators or the Program-
ming Console’s monitor operations. Check the input wiring with the
Slaves input indicators, the Programming Console’s I/O monitoring, or
the Programming Console’s multiple address monitoring.
3. Test Run
Use a Programming Console to set the SRM1 to RUN or MONITOR mode
and check that the “RUN” indicator lights.
4. Program Input
a) Use the Programming Console, SYSMAC-CPT, or SYSMAC Support
Software (SSS) to write the program.
b) Check the sequence of operation.
Note When using the SYSMAC-CPT Support Software, set the PC model
to “SRM1.” When using the SYSMAC Support Software, set the PC
model to “CQM1.”
5. Debugging
Correct any programming errors that are detected.
5-1-3 Flash Memory Precautions
The SRM1 uses the flash memory to hold the contents of the user program
memory, the read-only DM area (DM 6144 through DM 6599), and PC Setup
(DM 6600 through DM 6655). Observe the following precautions to protect the
flash memory and ensure proper operation.
1, 2, 3...
1. Perform either one of the following to write the above contents onto the flash
memory.
a) Switch the SRM1 to RUN or MONITOR mode.
b) Restart the power supply to the SRM1.
Note If the power is turned off without changing the mode after making
changes in the above areas using a Peripheral Device, the changes
will not be written to flash memory. Although the data in these areas is
backed up by a lithium battery, the changes will be lost if the battery
fails or is removed because the program in the flash memory will be
automatically read into the user program memory. The standard ser-
vice life of the lithium battery is ten years minimum under an ambient
temperature of 25°C.
2. When the SRM1 is operated for the first time after changing the program
memory, the read-only DM area (DM 6144 through DM 6599), or PC Setup
(DM 6600 through DM 6655), it will take about 850 ms longer than usual be-
fore the SRM1 starts. Be sure to take this one-time startup delay into ac-
count.

Entering the Program
Section 5-2
3. If one of the following three operations is performed in MONITOR or RUN
mode, a “cycle time over” warning will not be issued. When performing on-
line edit operation, take the I/O response time of the SRM1 into account. The
SRM1 will extend the cycle time for up to 850 ms and interrupts will be dis-
abled 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)

Error Processing
Section 5-4
5-4 Error Processing
The SRM1 is equipped with a variety of self-diagnosis functions to help identify
and correct errors that might occur and reduce down time.
Errors are divided into two categories based on their severity. Fatal errors are
more serious errors which stop SRM1 operation. Non-fatal errors are less seri-
ous and don’t stop SRM1 operation.
5-4-1 Non-fatal Errors
SRM1 operation and program execution will continue after one or more of these
errors have occurred. Although SRM1 operation will continue, the cause of the
error should still 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.
9B
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
F8
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 SRM1 can be set so that this error won’t be detected.)
Communication Error None
(no message)
If an error occurs in CompoBus/S communications, the COMM indicator will be off
and the ERC indicator will be lit. There is no error flag. Check the Slave and the
connecting cables and restart.
The COMM indicator will be OFF if an error occurs in communications through the
Peripheral Port or RS-232C Port. AR 0804 will be ON if an error occurred in
communications through the RS-232C port. AR 0812 will be ON if an error occurred in
communications through the peripheral port. Check the connecting cables and restart.
5-4-2 Fatal Errors
SRM1 operation and program execution will stop and all outputs from the SRM1
will be turned OFF when any of these errors have occurred. SRM1 operation
cannot be restarted until the SRM1 is turned off and then on again or the Pro-
gramming Console is used to switch the SRM1 to PROGRAM mode and clear
the fatal error.

Check and correct the settings in the read-only DM area.
AR 1311 ON: A checksum error has occurred in the PC Setup. Initialize all of the PC
Setup and reinput.
AR 1312 ON: A checksum error has occurred in the program. Check the program and
correct any errors detected.
AR 1314 ON: Power interruption hold area was not held. Clear the error and reset the
settings of the power interruption hold area.
AR 1315 ON: An error has occurred in CompoBus/S communications. If the error
cannot be corrected, replace the SRM1.
NO END INST
F0
END(01) is not written in the program. Write END(01) at the end of the program.
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.
9F
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.
5-4-3 Identifying Errors
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 er-
ror code is written to SR 25300 to SR 25307. (The error code is an 2-digit hexa-
decimal code.)
5-4-4 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 SRM1.
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 SRM1 will flash, but 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. 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.

Error Processing
Section 5-4
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 outputs will be turned OFF.
2. The ERR indicator on the SRM1 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. The
same number cannot be used as both an FAL number and an FALS number.
To clear an FALS error, switch the SRM1 to PROGRAM Mode, correct the cause
of the error, and then clear the error using the Programming Console.
MESSAGE – MSG(46)
MSG(46) is used to display a message on the Programming Console. The mes-
sage, which can be up to 16 characters long, is displayed when the instruction’s
execution condition is ON.
5-4-5 Reading/Clearing Error Messages
This operation is used to display and clear error messages. It is possible to dis-
play and clear non-fatal errors and MESSAGE instruction messages in any
mode, but fatal errors can be displayed and cleared in PROGRAM mode only.
RUN
MONITOR
PROGRAM
OK

Before inputting a new program, any error messages recorded in memory
should be cleared. It is assumed here that the causes of any of the errors for
which error messages appear have already been taken care of. If the buzzer
sounds when an attempt is made to clear an error message, eliminate the
cause of the error, and then clear the error message. (Refer to 5-7 Trouble-
shooting Flowcharts for troubleshooting information.)
Key Sequence
Follow the procedure below to display and clear messages.
1. Press the CLR Key to bring up the initial display.
1, 2, 3...

If there are messages, the most serious message will be displayed when the
MONTR Key is pressed. Pressing MONTR again will clear the present mes-
sage and display the next most serious error message. Continue pressing
MONTR until all messages have been cleared. These are some examples
of error messages:
A memory error:

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 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 ERR
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.
B
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

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.

Standard Models
There are three possible power supply configurations.
• Network Power Supply:
Power is provided from a single source over a network, using special-purpose flat cable.
• Multiple Power Supply:
Power must be provided separately for communications and I/O. The power supply for communications can be
provided via special-purpose flat cable, but the power supply for I/O cannot.
• Local Power Supply:
Power can be provided from a single source, which can be a source other than the special-purpose flat cable.
SRT1-series Remote Terminals and Sensor Terminals can operate in high-speed communications mode only. Be
sure to use SRT2-series Remote Terminals and Sensor Terminals when the SRM1(-V2) is used in long-distance
communications mode.
The Analog I/O Terminals can be used with SRM1(-V2) PCs only.

The process used to execute a ladder-diagram program. The program is ex-
amined sequentially from start to finish and each instruction is executed in turn
based on execution conditions.
scan time
See cycle time.
scheduled interrupt
An interrupt that is automatically generated by the system at a specific time or
program location specified by the operator. Scheduled interrupts result in the ex-
ecution of specific subroutines that can be used for instructions that must be ex-
ecuted repeatedly at a specified interval of time.
SCP
See subtract count input.
seal
See self-maintaining bit.
self diagnosis
A process whereby the system checks its own operation and generates a warn-
ing or error if an abnormality is discovered.
self-maintaining bit
A bit that is programmed to maintain either an OFF or ON status until set or reset
by specified conditions.
series
A wiring method in which Units are wired consecutively in a string.

Glossary
set
The process of turning a bit or signal ON.
set value
The value from which a decrementing counter starts counting down or to which
an incrementing counter counts up (i.e., the maximum count), or the time from
which or for which a timer starts timing. Set value is abbreviated SV.
shift input signal
shift register
An input signal whose OFF to ON transition causes data to be shifted one bit.
One or more words in which data is shifted a specified number of units to the right
or left in bit, digit, or word units. In a rotate register, data shifted out one end is
shifted back into the other end. In other shift registers, new data (either specified
data, zero(s) or one(s)) is shifted into one end and the data shifted out at the oth-
er end is lost.
signed binary
A binary value that is stored in memory along with a bit that indicates whether the
value is positive or negative.
signed decimal
One-word signed hexadecimal values stored in the two’s complement format
can be displayed at the Programming Console as decimal values from –32,768
to 32,767.
software error
An error that originates in a software program.
software protect
A means of protecting data from being changed that uses software as opposed
to a physical switch or other hardware setting.
source (word)
The location from which data is taken for use in an instruction, as opposed to the
location to which the result of an instruction is to be written. The latter is called
the destination.
special instruction
An instruction input with a function code that handles data processing opera-
tions within ladder diagrams, as opposed to a basic instruction, which makes up
the fundamental portion of a ladder diagram.
SR area
SSS
A memory area containing flags and other bits/words with specific functions.
See SYSMAC Support Software.
store
The process of recording a program written into a display buffer permanently in
memory.
subroutine
A group of instructions placed separate from the main program and executed
only when called from the main program or activated by an interrupt.
subroutine number
subtract count input
A definer used to identify the subroutine that a subroutine call or interrupt acti-
vates.
An input signal used to decrement a counter when the signal changes from OFF
to ON.
SV
See set value.
switching capacity
synchronous execution
The maximum voltage/current that a relay can safely switch on and off.
Execution of programs and servicing operations in which program execution
and servicing are synchronized so that all servicing operations are executed
each time the programs are executed.
syntax
The form of a program statement (as opposed to its meaning).
syntax error
An error in the way in which a program is written. Syntax errors can include
‘spelling’ mistakes (i.e., a function code that does not exist), mistakes in specify-
ing operands within acceptable parameters (e.g., specifying read-only bits as a
destination), and mistakes in actual application of instructions (e.g., a call to a
subroutine that does not exist).
