Modbus TCP is a communication protocol used in industrial automation systems. It allows devices like sensors and controllers to exchange data over a TCP/IP network. This protocol is widely adopted due to its simplicity and ease of implementation, making it suitable for various applications. The Modbus protocol operates in a master-slave configuration, where a master device requests information from slave devices. Data is transmitted in a structured format, ensuring reliable communication. Modbus TCP is particularly useful for connecting devices over long distances and integrating different types of equipment within a network.
