The Modbus TCP/IP protocol is a cornerstone in the realm of industrial communication systems. It is an application layer messaging protocol that works in conjunction with ethernet, to enable client/server communication between devices connected on different types of networks. Originating as a Modbus serial protocol (Modbus RTU), Modbus has evolved to embrace modern technologies such as TCP/IP, playing a crucial role in areas ranging from building automation and energy management systems to complex industrial automation processes. With a focus on simplicity and robustness, this protocol has widespread adoption due to its ease of use, openness, and ability to integrate diverse devices into a network, making it the protocol of choice for many applications.
