Modbus TCP
Modbus TCP is an industrial communication protocol that extends the classic Modbus protocol over TCP/IP networks, enabling devices like PLCs, sensors, and HMIs to exchange data in industrial automation systems. It uses a client-server architecture where a master device (client) sends requests to slave devices (servers) to read or write data registers, facilitating real-time monitoring and control. As a widely adopted standard, it simplifies integration across diverse hardware from different manufacturers in settings such as manufacturing, energy, and building automation.
Developers should learn Modbus TCP when working on industrial automation, IoT, or SCADA systems that require reliable, real-time communication between devices over Ethernet networks. It is essential for projects involving PLC programming, data acquisition from industrial sensors, or integrating legacy equipment with modern IT infrastructure, as it offers a simple, open standard that reduces compatibility issues. Use cases include factory automation, smart grid management, and environmental monitoring where low-latency, deterministic data exchange is critical.
