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.)
