How to communicate to Allen Bradley PLC over OPC Server?
I am quite new to ABB Freelance. I am working with Freelance version 2013 and 803F controller. I set the OPC server on the engineering system to read and write data from/ to other Allen-Bradley controllers(one RSLogix and One Compact Logix).I changed the resource of some signals to OPC as I am supposed to read data from the other controllers.For the data I am sending, I did not change the resource.Now, how Should I establish the communication between those systems and send/receive data?
What configuration should be done on the other sides?
One of the option, what we are using in a project at this moment, is to connect the Freelance OPC server to the RSlink. The connection between both OPC was done with OPC Tunnel. All OPCs can be installed in the same node, OPC node belong to the freelance control network.
