MODBUS TCP Interface
Use MODBUS TCP software to pull in gateway and sensor data. Monnit provides a
register map. Check the box to make the interface Active and Save.
The MODBUS TCP Interface will store all data values in 16-bit registers. The registers
and their data elds are mapped below:
Field Description Register Data
