I am working with PLCs and automation systems for seven years. All these years I am learning for different types of communication (Profibus, ArcNet, RCOM, Modbus, Ethernet etc) What is the
reason (except the commercial) of having so many "different" communication protocols instead of having one common protocol for all systems which will give the possibility (if the companies
wanted to do so) to connect different systems (PLC, SCADA, SENSORS etc) from various companies?
I am looking forward to receiving from you
