5.4 Safety Signal Output Value

Safety Signal Output Value
The output signal outputs the status of safety or not safety over the
monitoring conditions when the object condition file is validated.
Followings show the meanings of output result for each safety function.
Basically, output signal ON is defined as safety side and OFF is defined as
not safety side in preparation for the disconnection of the hard signals, etc.
In case the status becomes not safety and OFF is output during the
monitoring, the OFF signal is kept outputting unless the error alarm is re-
set.
If the alarm is set to be out of occurring by a condition file, the signal keeps
outputting OFF while in not safety status and becomes ON when it returns
to the safety status.
In case a major alarm occurred in the functional safety function, all the
output signals are turned OFF.
