I am really confused with protocol communication in s4c systems
There are some types of protocol such as 350 (DeviceNet ) and 351 (InterBus - S)
The manual says that these units expand amount of Input/Output signals
But then I don't quite understand how can I configure a program "word" or pass commands
For example I want to connect Fronius 4000 via DeviceNet and I have commands to control it. (like weld correction , wire speed , schedule number, any supervision outputs)
How can I program s4c controller to pass needed commands
I read that I can divide signals by groups of 8 signals (in result I have 1 byte of information) but still don't understand how to control it
And what about PLC?
What is the best practice to connect PLC? How it works?
