1.3 Serial and Ethernet-Based Communication Protocols

Historically, serial-based protocols were used for factory automation due to their low cost and ease of use. Examples include DeviceNet, CanOpen, Profibus, and Modbus Serial. However, they have lower communication speeds and limited reach for high-speed communication.

With advancements in Ethernet technology, industrial Ethernet protocols like Ethernet/IP, PROFINET, and EtherCAT have become more prevalent, offering 100Mbps data rates over 100BASE-TX Ethernet. Newer protocols, such as Time-Sensitive Networking (TSN), PROFINET TSN, and CC-Link IE TSN, support 1000Mbps data rates.
