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-5850Gis a modbus gateway product dedicated to connecting Modbus TCP devices and Modbus RTU/ASCII devices.

ADM-5850Ghas 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.
