hi,
I have a NI OPC server in my lab . I want to send the data from B&R plc to the OPC server. I have tried to search for a solution but could not find any.
Kindly help me in establisihng a communication between the B&R plc and the OPC server.
Regards

Have you looked at the following page?
Supported Device & Driver Plug-in List for NI OPC Servers

As an additional note, I have not used the NI OPC server. But I have used Think&Do WinPLC's where I had to install Think&Do OPC software so LabVIEW could read the OPC tags.

Thanks for your reply but in the link there is no mention of any support for B&R plcs. I have searched for it earlier but could not find any case where anyone has set up a communication between NI OPC server and B&R plc. i actually need some data from the plc to be transfered to the server.

please explain which communication/ protocol you are using?

communication protocols is TCP/IP . Actually NI OPC provies the interfaces for other plcs like siemens but we are not able to interface B&R plc to NI OPC, even nothing is given in the http://www.ni.com/white-paper/6417/en link.

Did you try installing the B&R PLC OPC server on a computer and then see if the NI OPC server can connect to it? It might not be the most elegant soloution, but it might work.
We were having problems with some siemens wincc software that would not connect to the Think&Do OPC server. So I had to bring the Think&Do OPC tags into LabVIEW and then have LabVIEW broadcast the data so the Semens OPC software could see it. I did not like doing it, but it worked.
Other than that, maybe someone else will have more to offer.

What kind of data you are passing through PLC to OPC or vice versa.
If you are using TCP/IP communication, try using MODBUS. It need some programming work at B&R side if you are using AS2.7.
If it is AS 3.0 then the ready made Modbus Slave & Master examples are available.
