I do not know the reason. I suspect that it will be in the OPC server. Have you tried some other OPC client to test out whether it behaves the same?

WriteItem get slow when another OPCServer try to read Items from the same PLC was created by LuisGar

We are having a problem when we are trying to update the value of a OPCitem, we update its value every 500 ms, but at the moment the Visualization tool used by Phoenix Contact, try to update it variables, the ReadItem operatins tooks much longer than usual, as soon as I change the visualization page, I can see the delay in my reading function.

Do you have any idea why this is happening?

The OPC server is from Phoenix Contact, and the Visualization Software is also from Phoenix Contact

Best Regards
