How do I get my HMI to display what is happening according to the inputs and outputs on my PLC/field device.
When I am working with the HMI software like the WinCC flexible. I think I connect the OP 77 to the PC, make my display the way I want. Then on the other hand, my PLC itself has a program. How do I get the HMI to display what's happening with my PLC and field devices?
I tried finding links for this, but couldn't find one that speaks clearly on the connections. I did work with the HMI programming through the software WinCC flexible, and even worked on the receipe.
But given that ultimately its my PLC (and not HMI) which has the logic of the receipe, I don't understand how programming of the HMI with a receipe makes any sense. Could anyone explain interfacing the HMI with a given industrial system/process?
