Modbus protocols are essential components in the realm of industrial automation and control systems. Designed in 1979 by Modicon (now Schneider Electric), Modbus was developed as a way to enable communication between Programmable Logic Controllers (PLCs) and other devices in industrial networks. Over time, the protocol has evolved, and its versatility has made it a popular choice in various industries, with RTU and TCP protocols being prominent among them.
