I’ve noticed something from time to time that I can’t fully explain: I have a transaction group with one boolean value (read only) used as a flag and a second item (a string). The string is a date-time which is written to a db table. Occasionally, when the trigger activates an old value is written. I’m certain that the PLC value is correct before the flag is set. Is it possible that the values weren’t read by the OPC at the same time? Is there a way to be sure these values are synched?
