Hello, Im trying to use 4Diac with OPC UA to connect it to an application at Factory I/O, I mean to use subscribe to active an event in other FB, but my subscriber keeps acticvating the event 'IND', without any change at tha variable at the ID

Unfortunately this is partly a problem of Factor I/O. Factory I/O is writing values to the OPC UA server all the time and our Subscribe block will get an IND everytime the value is written even if it is not changed.
