can't connect to NIOPC server

[Pelagon]

Dear All,

I have SCADA application where I am communicating with Omron PLC thought Ethernet using NIOPC server. Everything work well on the PC where are installed Labview and DSC module. If same application is run on different PC where is installed and configured only NIOPC server, I have problem with communication between my application and OPC server. Communication between PLC and OPC server is OK. Please any suggestion how to avoid that. I/O server is configured in project directory.

Thank you

Hello Pelagon,

Are you doing datalogging on your computer that does not have dsc? (datalogging on shared variables)

Is the application only complaining about the shared variables which you are doing datalogging on?

I could be wrong, but the thing that sticks out the most here is that you mention dsc on one computer but then there is  a built application that is used on another computer without dsc. If you do not have the DSC Run-Time System on that computer and licensed, as well as have DSC Run-Time Support enabled for your application then the application will fail on the mchine without it for the shared variables that you are doing datalogging on. The rest of the application that you aren't doing datalogging on should act normally withot failing. I think this is why NI-OPC Servers works but the (possibly) the dsc (without the DSC Run-Time System) does not.

Regards,

Andrew Eddleman
