PRECAUTIONS]

A
malfunction in the GOT main module, communication module, bus connection module, com-
munication cable, and bus connection cable may keep the output ON or
OFF.
Add
a
circuit to
externally monitor the
output
which could lead to a serious accident.
An
accident may occur by a false output or a malfunction.

If a communication error (including by a disconnected cable) occurs
while
the
monitor
is running
on the GOT, the communication between the GOT and the PC CPU is interrupted, and the GOT
stops running.
When using the bus connection: PC CPU goes down and the GOT stops running.
When not using the bus connection: GOT is not operational.
For
a
system configuration using a GOT, design the system such that the crucial switching to the
system is performed by the equipment other than the GOT with the assumption that a communi-
cation error could occur in the GOT.
An
accident may occur by a false output or a malfunction.
