Batu Automation Modbus protocol to Profinet protocol gateway module connects smart instruments and PLC communication

1. On-site requirements: PLC acts as a controller and instrument equipment acts as an execution device. The execution device can respond to the instructions from the PLC in real time and feed back data to the PLC, so that the PLC can control and monitor the instrument equipment and realize precise control of the production process.

2. Solution: Through the connection of Batu Automation Modbus protocol to Profinet protocol gateway module (BT-MDPN100), PLC or controller can realize remote monitoring and data transmission of instrument equipment, improving production efficiency and operation stability. Modbus protocol to Profinet protocol gateway module serves as a bridge to connect devices, converting communications between different protocols to make the information flow of the entire system smoother.

3. Functions and advantages: The main function of the Batu Automation Modbus protocol to Profinet protocol gateway module (BT-MDPN100) is to realize the conversion and communication between the Modbus protocol and the Profinet protocol. The Modbus protocol to Profinet protocol gateway module integrates two protocols, Modbus and Profinet, supports Modbus RTU master/slave, and can be connected to RS485 interface devices. It has its own network port and serial port, which can realize both protocol conversion and interface conversion.
