This driver is designed for use with WattNode Modbus Module (WND) WattNode Modbus (WNC) and Multi-Circuit meter (MCM). This driver is included with the “Basic ezeio service” package and provides a limited set of power circuit measurements. The full set of measurements is available from the “WattNode Advanced” driver included in the “Meters” driver package.

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) - Drop-down menus are provided for selecting CT ratings for each of the three phases metered.
