I have been experimenting with a way to make a heartbeat bit exchange from a PLC to FSQL and back out to the PLC to verify communications. I have a two second timer in the PLC which flashes a bit on and off at two second intervals that I can’t seem to loop through FSQL back to the PLC to read and set an alarm. I am afraid that I’m not seeing this clearly but I can’t get the signal back out to write to the PLC. I have tried making action items in various ways with no luck. Is there someone who can point me in the right direction through this seemingly simple task? I want to use this bit to prove that I have communications with FSQL and the SQL database for validation. Is there another way to do this without having FPMI running?
