Modbus map
Your meter’s default Modbus register information (map) is available on www.se.com.
The Modbus register information includes:
- Registers and mapped values
- Formats and scaling
- Additional details where applicable
Note: Your meter’s Modbus registers are specified differently than previous devices using ION architecture. If you are configuring Modbus client information on your meter, confirm you are using the appropriate Modbus register addressing. For more information, refer to your meter’s Modbus map.
Your meter has a fixed (static) register map which contains the most common metering values. This map is defined by a series of Data Mapping modules, which also determine the values shown on the meter webpages or the display. The Data Mapping modules are named based on the type of information they map to Modbus:
| Data Mapping module | Description |
|---|---|
| Data Mapping Dmd | Maps kW, kVA and kVAR demand data such as kW sd del (sliding demand kilowatts delivered), as well as current demand such as I a sd (sliding demand phase A current). |
| Data Mapping Egy | Maps kWh, kVAh, and kVARh delivered, and received data, including conditional, quadrant, and incremental energies. |
| Data Mapping EN | Maps present interval EN 50160 power quality compliance data. |
| Data Mapping EN Prev | Maps previous interval EN 50160 power quality compliance data. |
| Data Mapping IEEE519 | Maps IEEE 519 harmonics compliance data. |
| Data Mapping I/O | Maps input metering data, alarms, resets, and reset counts. |
| Data Mapping Meas | Maps voltage, current, power, power factor, and frequency data for one second and half-cycle measurements. The Cfg Modbus Map Enable setup register may exist in this module. |
| Data Mapping PQ | Maps power quality data such as Crest Factor, K Factor, and
total harmonic distortion, including IEC 61000-4-30 power quality
compliance data |
| Data Mapping Stats | Maps statistical low, mean, and high data values, such as I a mean (phase A current average value). |
| Data Mapping TOU | Maps time-of-use (TOU) data, such as seasons, rates, and per-season demand, such as kW sd rec A (sliding demand kilowatts received in season A). |
You can add extra Modbus information or duplicate information that is already in the fixed map to different Modbus registers using Modbus Slave modules.
