Common IT protocols

Electrical devices inherently do not understand any form of language that we humans can speak. All a device such as a computer or PLC understands is whether a particular pin is energized at a given time or not. Specific languages known as protocols have to be used so that one device knows what the other device is saying. There are many different protocols out there. Some are very common and are used everywhere, while some are proprietary and are only used with specific devices. The following section is going to be dedicated to exploring two common, everyday protocols that can be used with PLCs and other automation devices. These protocols can be used directly or as an underlying system for more specific protocols. As such, the first protocol stack that we will explore is TCP/IP.

TCP/IP

Arguably the most common form of computer communication is called the Transmission Control Protocol (TCP). TCP is one of, if not the most commonly used communication protocols...
