Modbus Gateway for Vantage Pro2

The Modbus interface for Vantage Pro2 weather stations allows you to easily connect a PLC (Programmable Logic Controller), RTU (Remote Terminal Unit), or SCADA system to a Davis Instruments Vantage Pro2 weather station.

Using the MODBUS protocol, your PLC can monitor weather parameters and take automation actions based on wind speed, wind direction, temperature, and many other variables.

Compatible weather stations:

The GWY-141 Modbus interface is compatible with the following Davis Instruments products associated with a WeatherLink SERIE 6510SER data logger.

• Vantage Pro2 cable 6152CEU
• Vantage Pro2 Plus cable 6162CEU
• Vantage Pro2 Wireless 6152EU
