Am I right in my protocol hierarchy? (Ethernet up to fieldbus)
Am I right in my protocol hierarchy? (Ethernet up to fieldbus)
(OP)
Am I right to say that on an Ethernet network PLC communicate with fieldbuses which are "encapsulated" in RS-485 protocol which is "encapsulated" in TCP/IP protocol. If i'm wrong could someone tell me what is the correct hierarchy.
