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?
