Digital PI Points on OPC interface needs to apply SquareRoot from a specific date

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 !
