Overview
The MQTT Wi-Fi / Ethernet / Serial Gateway, GW211W-MQ provides an easy to deploy device to send RS-232/RS-485 Serial Modbus RTU Data communications to MQTT TCP networks on hard-wired Ethernet or over wireless WiFi networks. The MQTT Gateway works with standard Modbus Slave device, such as PLCs, IoT Sensors, Energy meters (AMRs), Solar Inverters, Wind Turbines, IO Modules, Flow Meters and more. The MQTT Gateway is built for use in light industrial environments and features a compact wall-mount design. It operates from 9-32VDC power supply voltages with both DC Jack and terminal block connectors and is easy to configure through its web GUI interface.
Technical Notes
Modbus Notes
Modbus TCP / RTU integration
Since its inception in 1979 Modbus has become a widely used communication protocol in the field of industrial automation. Originally based on serial interfaces (RS232 and RS485) Modbus RTU enjoys widespread use throughout many different industries. Since then Ethernet has become the network of choice and many industrial devices now have native Ethernet interfaces.
