Description
Functional introduction
The Modbus protocol is the most widely used protocol in the electronic industrial equipment, and now it has become a general industrial standard. Through this protocol, Modbus devices (such as PLC, DCS, HMI, and instruments) can communicate with each other through a network or serial port. But the Modbus protocol used in the serial port and the Ethernet network is different, so a gateway is needed to complete the communication conversion between the two protocols. IDM-7842MG is a modbus gateway product dedicated to connecting Modbus TCP devices and Modbus RTU/ASCII devices.
IDM-7842MG is an isolated Modbus gateway device with multiple network ports. It integrates 5 port 10/100Mswitches and 2 serial port Modbus gateways. Users can use any port and 2 port RS-485/232 serial port to convert Modbus TCP and Modbus RTU/ASCII protocol. The 2 port RS-485/232 serial port has photoelectric isolation. It is integrated with Modbus TCP, Modbus RTU and Modbus ASCII protocol, and the serial port can be configured flexibly into RS-485 or RS-232 mode through software, which can easily realize the connection between Modbus Ethernet device and Modbus serial device.
