Answer Posted / rnm
In my opnoin, Sacn time checking during FAT shall be input
simulation with one repeater block. Then go for cycle sacn
rate check, which will cover input,process block(PID) and
output. We know, there wiil be no O/P connected in field
and no much execution of loops. In this case, very
difficult to conclude this time.Better to check I/O
scanning rate.
