There is no way to insert P and N contacts

Recommended Posts

Is this a UDFB? If so, keep in mind there is no retained memory of local variables after a UDFB executes. Transition contacts require retained memory in order to know a transition occurred.

OK. How to organize the processing of the algorithm along the rise and fall inside UDFB? The structure in the image continues to be processed in a loop, even after setting the ON bit. I mistakenly inserted a coil instead of a contact, but even if there is a contact, the circuit repeats itself cyclically until the Alarm.Active bit is true
