Pm2100 Modbus Register List !free! (PREMIUM)

Look for a file named PM2100_Modbus_Map.xls or PM2100_Register_List.pdf . These spreadsheet-style documents are easier to parse than PDF manuals.

The PM2100 typically supports (binary) over RS-485, and sometimes Modbus TCP over Ethernet. It uses a standard register address space, but engineers often fall into a critical trap: the difference between Protocol Address (0-based) and Modbus Address (1-based). pm2100 modbus register list

| Parameter | Protocol Address (Dec) | Data Type | Range | Description | |-----------|------------------------|-----------|-------|-------------| | Primary Voltage (PT Ratio) | 200 | UINT16 | 1-65000 | Primary voltage (e.g., 13200 for 13.2kV) | | Secondary Voltage | 201 | UINT16 | 60-690 | VT secondary (e.g., 120V) | | Primary Current (CT Ratio) | 202 | UINT16 | 1-32767 | CT primary (e.g., 200 for 200:5A) | | Secondary Current | 203 | UINT16 | 1-10 | CT secondary (typically 5 or 1 Amp) | | Modbus Slave ID | 204 | UINT16 | 1-247 | Device Modbus address | | Baud Rate | 205 | UINT16 | 0-4 | 0=2400, 1=4800, 2=9600, 3=19200, 4=38400 | | Parity | 206 | UINT16 | 0-2 | 0=None, 1=Odd, 2=Even | Look for a file named PM2100_Modbus_Map
