PLC/automation device communication

UDP and TCP are general communication protocols. By this, I mean that they are used for many different types of IT applications, such as internet applications, common computer networks, and so on. However, many of the PLC manufacturers produce their own communication systems to be used with their PLCs and various types of industrial components. Some of these systems are very similar and use the same physical connectors as standard computers do – for example, Ethernet cables. However, some use exotic connectors and will be unique for certain devices. The first communication protocol we are going to discuss is one of the most popular, which is called Modbus.

Modbus

Modbus is an industrial communication protocol. Modbus is a little different than the other protocols that we have discussed thus far. Where TCP and UDP are more agnostic in terms of IT applications, Modbus was developed in the late 70s for use in PLC communications by the company...
