This driver is designed for use with WattNode Modbus Module (WND) WattNode Modbus (WNC) and Multi-Circuit meter (MCM).

Name - The name is up to the user. Our suggestion is to choose a naming convention that makes the viewing the device list intuitive. Such as referring to the sensor and/or application. Keep the name short as it will be combined with the register name to create the default “Field” name (if added to “Fields”)

Active Check box - Check this box and “Save changes” to run the driver. The driver program can be suspended by unchecking the box and clicking on “Save changes”.

Notes - This space can be used to store information specific to the device, such as: location, wiring, scaling, etc.

Address - Enter the RTU device number (must be unique on the bus) or the last octet of the IP address, if connected via Ethernet/TCP

Module - Default setting is RTU for WattNode WND & WNC models. For Multi-Circuit Meter (MCM) select the corresponding Unit (circuit) number.

CT (A, B, & C) - Enter the CT ratings for each of the three phases metered.

Serial number (optional) - The serial number of a WattNode can be used to validate the meter data. Since the Modbus ID is how the meter (devices) are identified on the bus, changing the Modbus ID changes the data mapped to the ezeio Fields. If a serial number is entered into this field, the driver will check the serial number before accessing the data on the meter.
