3Safety Precautions
xii
1 Intended Audience
This manual is intended for the following personnel, who must also have knowl-
edge of electrical systems (an electrical engineer or the equivalent).
•Personnel in charge of installing FA systems.
•Personnel in charge of designing FA systems.
•Personnel in charge of managing FA systems and facilities.
2 General Precautions
The user must operate the product according to the performance specifications
described in the operation manuals.
Before using the product under conditions which are not described in the manual
or applying the product to nuclear control systems, railroad systems, aviation
systems, vehicles, combustion systems, medical equipment, amusement
machines, safety equipment, and other systems, machines, and equipment that
may have a serious influence on lives and property if used improperly, consult
your OMRON representative.
Make sure that the ratings and performance characteristics of the product are
sufficient for the systems, machines, and equipment, and be sure to provide the
systems, machines, and equipment with double safety mechanisms.
This manual provides information for programming and operating the OMRON
SRM1. Be sure to read this manual before attempting to use the software and
keep this manual close at hand for reference during operation.
WARNING It is extremely important that an SRM1 and all CompoBus/S Units be used for the
specified purpose and under the specified conditions, especially in applications
that can directly or indirectly affect human life. You must consult with your
OMRON representative before applying a CompoBus/S System to the
abovementioned applications.
3 Safety Precautions
WARNING Never attempt to disassemble any Units while power is being supplied. Doing so
may result in serious electrical shock or electrocution.
WARNING Never touch any of the terminals while power is being supplied. Doing so may
result in serious electrical shock or electrocution.
WARNING Provide safety measures in external circuits (i.e., not in the Programmable
Controller), including the following items, in order 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 doing so may result in serious accidents.
•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.

5Application Precautions
xiii
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.
4 Operating Environment Precautions
Do not operate the control system in the following places.
•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.
Caution The operating environment of the CompoBus/S System can have a large effect
on the longevity and reliability of the system. Improper operating environments
can lead to malfunction, failure, and other unforeseeable problems with the
CompoBus/S System. Be sure that the operating environment is within the spe-
cified conditions at installation and remains within the specified conditions dur-
ing the life of the system.
5 Application Precautions
Observe the following precautions when using the SRM1.
WARNING Failure to abide by the following precautions could lead to serious or possibly
fatal injury. Always heed these precautions.
•Always turn off the power supply to the SRM1 before attempting any of the fol-
lowing.
•Assembling any devices or racks.
•Connecting or disconnecting any cables or wiring.
Caution Failure to abide by the following precautions could lead to faulty operation of the
SRM1 or the system or could damage the SRM1 or CompoBus/S Units. 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 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.)

5Application Precautions
xiv
•Use the Units only with the power supplies and voltages specified in the opera-
tion manuals.
•Take measures to stabilize the power supply to conform to the rated supply if it
is not stable.
•Provide circuit breakers and other safety measures to provide protection
against short-circuiting in external wiring.
•Install all Units according to instructions in the operation manuals.
•Do not install the Units in a place where they are subject to excessive noise in
order to avoid any trouble or 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.
•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.
•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.
•Before touching the Unit, be sure to first touch a grounded metallic object in
order to discharge any static build-up. Not doing so may result in malfunction or
damage.
•Use, store, and transport the Units within the specifications provided in this
manual.
•Resume operation only after transferring to the new SRM1 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.
•Be sure to observe local ordinances and laws when disposing the Units.
