cRIO communicating as PLC with NI-OPC-Server

[r.tara]

Hi there,

i have the task to implement a communication between multiple cRIO's and the NI-OPC-Server. The NI-OPC-Server has to act as data handler for a complex frontend.

I tried out the NI-OPC-Server and i was successful in communicating with the NI-OPC-Server as OPC-Client in Windows using an IO-Server and Shared Variables. But the task is to do this on a cRIO. I tried to open a data socket connection from a cRIO to the NI-OPC-Server using a specific URL using "DataSocket Select URL.vi". But as long i do not activate simulation in the NI-OPC-Server i get errors on opening the data socket connection. If i do activate the simulation, which is not the solution, i can write some data without error but the Quick Client of the NI-OPC-Server sees no changes for that data tag.

I have the feeling i am not at a good way to get this working. Is there anybody having experiences with this? Is data socket a possible way at all? Is it possible at all? Do i need to implement a cRIO-OPC-driver?

Thank you.

Hi,

There's one pretty good tutorials and one webcast. Have you already study them?
