Reference: Modbus Registers
This section provides the default register mapping for WAGO energy analyzers. Ensure your device configuration matches these addresses for accurate data visualization.
Standard Energy Meter Registers (879 Series)​
| Register Address | Parameter | Data Type | Units |
|---|---|---|---|
0x0002 | Phase 1 Voltage | Float32 | V |
0x0004 | Phase 2 Voltage | Float32 | V |
0x0006 | Phase 3 Voltage | Float32 | V |
0x0008 | Phase 1 Current | Float32 | A |
0x000A | Total Active Power | Float32 | W |
0x0010 | Total Active Energy | Float32 | kWh |
IMPORTANT: Due to WEVA uploads a csv to file to define address and path of the MODBUS device, make sure to create valid csv files to avoid errors. Download the example csv file to get started. Example CSV
Writable Control Registers​
Admins can modify these registers via the Control interface.
| Register Address | Function | Range | Default |
|---|---|---|---|
0x1000 | Alarm Threshold (High) | 0 - 5000 | 4500 |
0x1002 | Reset Energy Counter | 1 = Reset | 0 |
Troubleshooting Data Accuracy​
If values appear distorted (e.g., massive numbers):
- Verify the Byte Order in the device settings (Standard: Big Endian).
- Ensure the correct Register Function Code (03 for Read Holding, 04 for Read Input) is selected.
