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.
