Modbus Gateway User's Manual
ADM-5850G
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. ADM-5850G is a modbus gateway product dedicated
to connecting Modbus TCP devices and Modbus RTU/ASCII devices.
ADM-5850G has Modbus RTU/ASCII and Modbus TCP protocol conversion functions, it
integrates Modbus TCP, Modbus RTU and Modbus ASCII protocol, and the device's serial port
can be configured by software of RS-232, RS-485 or RS-422, you can easily achieve Modbus
Ethernet devices with Modbus serial devices connected.
