Difference between Fieldbus and communication protocol
(OP)
What is the difference between a fieldbus and a communication protocol? Is it that a fieldbus is a communication protocol for different specific PLC's





RE: Difference between Fieldbus and communication protocol
Perhaps you are speaking of networking protocols such as ethernet, device net, modbus plus, etc. At any rate A field bus is a networking architecture which includes all physical devices used to join PLCs,drives, HMIs and I/O. A communication protocol is the rules that allow the field bus or networking architecture to function.
