Not able to write to OPC IO signals

Hi! I have some troubles writing to IO signals from OPC client. I have 2 IRC5 controllers connect to the OPC server, the connection works fine and I am able to read data. I have changed access level to ALL for the IO`s and the controller is in automatic mode. But I am not able to write to any of the IO signals. All signals are connected to a d653 unit. A also noticed that my OPC client shows the IO signals as UInt32 even though all my signals are either DI og DO.

Any help or suggestion on fault checking this issue is highly appreciated.

Thanks!

Espen Olsen
