Dear all,

I am using rexroth(Indra L20)PLC which as OPC and labview 8.5.In my application read/write the tags of plc through LabVIEW.Give me the steps to follow.

Sathish,

best thing to start with is using the Datalogging and Supervisory Control (DSC) Module in order to connect shared variables to the OPC server. Please note that there is no garantee for correct functionality though since OPC is not a strict definition but a mere collection of "could be's" (a little overexaggeration, but essentially true).

So if you cannot connect to the OPC server directly using DSC, you should use OPC tunneler from e.g. Matrikon.

In your LabVIEW VI, you will simply access shared variables which are connected to the OPC tags.

hope this helps,

Norbert

You might not need the opc software and DSC module. I had a setup with an Indramat MT-CNC where the serial port could be conifgured as a modbus port with logic commands. You might be able to do that and use the NI Modbus Library download. I have not used your specific plc model.
