Hello all !
I am not quite familiar with OPC interface. A lot of digital tags from AllenBradley Control Logix started to malfunction from a specific date in the past.. since the "0" part of the digitalset was fine, I suspected that the other value was something like "-1". So I added a SquareRoot on the point and tadam, everything is working fine.
But i really Wonder if I am doing this the good way or if I'm just putting some duct tape on the real problem...
Thanks for your feedback !
