Understanding Communication Protocols in Remote I/O Modules: Modbus RTU, Modbus TCP, and Modbus TCP/IP
In modern industrial automation, seamless data exchange between devices is the foundation of efficiency. Remote I/O Modules play a critical role in connecting sensors, actuators, and control systems, bridging the gap between field devices and supervisory systems like PLCs or SCADA.But what truly enables this communication?It’s the communication protocols, and among the most widely used […]
