This is the safe function block F_1oo2AI of a Siemens PLC:
This function block checks for valid inputs, compares the two inputs against a
configured delta tolerance and checks for a discrepancy time. See the manuals of the
used PCS for more information. The allowed deviation is set to "DELTA" = 1mA and
"DIS_TIME" = 1second.
