FB_MTP_BinMon
The function block FB_MTP_BinMon provides the binary input value V for manual operation (e. g. via OPC UA). A text can be assigned to the states TRUE and FALSE of the input value via the inputs VState0 and VState1.
Monitoring
The binary input value V can be monitored for flutter (change of input signal). The output VFlutAct goes TRUE if the change in the input signal per time interval VFlutTi exceeds the maximum value VFlutCnt .
The output signal VOut corresponds to the debounced input value V .VOut and follows a change in the input signal V after VFlutLen. The input signal V must retain its value for this time.
