[Design Precautions]
• Some failures of the GOT main unit, communication module, communication board or cable may
keep the outputs on or off.
An external monitoring circuit should be provided to check for output signals which may lead to
a serious accident.
Not doing so can cause an accident due to false output or malfunction.
• If a communication fault (including cable disconnection) occurs during monitoring on the GOT,
communication between the GOT and PLC CPU is suspended and the GOT becomes
inoperative.
For bus connection
For other than bus connection
A system where the GOT is used should be configured to perform any significant operation to
the system by using the switches of a device other than the GOT on the assumption that a GOT
communication fault will occur.
Not doing so can cause an accident due to false output or malfunction.
• Do not use the GOT as the warning device that may cause a serious accident.
An independent and redundant hardware or mechanical interlock is required to configure the
device that displays and outputs serious warning.
Failure to observe this instruction may result in an accident due to incorrect output or
malfunction.
