Real Compare Fcm - ABB 800xA Operation

Real Compare FCM

where
prev is the value of the result from the previous sample period
any non-zero input is treated as a 1
As long as inp2 (Reset) is 0, the result goes to 1 as soon as inp1 (Set) goes to 1. The
result remains at 1 regardless of the subsequent state of inp1. When inp2 goes to 1,
the result is forced to 0, and remains there as long as inp2 is 1.
