| Parameter | Protocol Address (Dec) | Data Type | Description | |-----------|------------------------|-----------|-------------| | Present Active Power Demand | 80 | Float32 | Current demand in Watts | | Peak Active Power Demand | 82 | Float32 | Maximum demand since last reset | | Present Current Demand (I1) | 84 | Float32 | Amps | | Peak Current Demand (I1) | 86 | Float32 | Amps | | Demand Reset Command | 100 | UINT16 | Write 1 to this register to reset peak demands |
The following are common real-time measurement registers found in the PM2100 series map. Most measurements use Float32 (IEEE 754) data types.

: Write the full command block (e.g., Command 2000 for Basic Setup) to registers 5000–5124 using your key. : Check the result in registers 5125–5127 . A zero in indicates success. : Write your access key back to to release control. Communication Setup Parameters | Parameter | Protocol Address (Dec) | Data
However, the true power of the PM2100 lies not in its local display, but in its serial communication capabilities via the . To unlock this data—voltage, current, power, energy, harmonics, and status—engineers and system integrators need a single, critical document: the PM2100 Modbus Register List . : Check the result in registers 5125–5127
The is your blueprint for turning raw serial data into actionable energy intelligence. By understanding the structure—where to find Float32 voltages at address 0, how to reset demands via address 100, and how to parse UINT32 energy at address 54—you can integrate the PM2100 into any PLC, RTU, or SCADA system with confidence.
When your master sends a request, the PM2100 may reply with an exception. Here is what they mean:
