Hi Mikhail
Thank you so much for your information.
But, ScadaCommMono.exe can’t work correctly. Specify a user account for Component Services and ScadaCommService can’t work correctly either.
I find the other opc client “Prosys OPC Client”,The OPC Client can get value correctly from two OPC Server.

Besides,I developed the demo program by “Scada.Comm.Svc.Manager” Class,the demo can get value of Device 61 “PNS” too.
I can’t solved the problem.
Thank you so much for your reading again.
