Hello,
I am relatively new to PLC programming. I have been asked to convert 984b ladder logic to IEC compliant FBD. One problem that I am having is finding a way to use a FB to simulate a ladder logic ADD block that is triggered by a relay. The ADD FB does not have an enable line associated with it.
Thanks,
Ken
