I am using the OPCAutomation.DLL to create an OPC Client in VB.Net. Everything works mostly ok, but the issue is I am getting multiple DataChange events firing, but the data never changed. I am trying to use the signal to do a print, but once in a while I will see multiple dataChange events and will double print.
I can’t attach the Image but the output in VB will look like this:
TimeStamp Value
——————————————
4/29/2024 6:39:57 PM True
4/29/2024 6:39:57 PM True
4/29/2024 6:39:59 PM False
4/29/2024 6:39:59 PM False
Has anyone encountered this before? It doesn’t happen constantly, but randomly throughout the day.
