DANGER
• 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 : The CPU becomes faulty and the GOT inoperative.
For other than bus connection : The GOT becomes inoperative.
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.
