Carlo Gavazzi WM15 power analyzer Modbus register map
Updated 16 October 2026
The WM15 is a 96x96 mm panel power analyzer with an RS485 Modbus RTU port. Values are mostly 32-bit integers sent low word first with fixed weights; functions 03 and 04 are equivalent and up to 125 registers can be read at once. This map covers voltages, currents, powers, PF (both sign conventions), frequency, energy totals and partials, run hours, THD, demand and max values, output/alarm status, alarm and pulse-output setup, serial settings, resets and device state.
This page lists 119 Modbus registers for the Carlo Gavazzi WM15 power analyzer — 22 writable — with the table, 0-based wire address, data type, word order, scale, units and access of each, re-typed from Carlo Gavazzi’s own free documentation (linked below) and checked against it.

Integration notes: Carlo Gavazzi WM15 power analyzer
Read input registers 0000h-0059h with function 04 (or 03) in one request; decode INT32 values low word first and apply the fixed weights (V and W x10, A and PF x1000, energy x10).
Minimum registers to map
Addresses are 0-based wire addresses. Enough to monitor and run the unit; map more as the job needs.
| Register | Name | Type | Why | Access |
|---|---|---|---|---|
| IR 0 | V L1-N | INT32 CDAB | V L1-N | Read |
| IR 12 | A L1 | INT32 CDAB | A L1 | Read |
| IR 40 | W system | INT32 CDAB | W system | Read |
| IR 49 | PF system | INT16 | PF system | Read |

| IR 78 | kWh(-) total | INT32 CDAB | kWh(-) total | Read |
Enable Modbus control & writes
Modbus RTU is on the OS (RS485) versions; OX versions have no serial port. Address, baud rate, parity and stop bits are in registers 2000h-2003h.
Byte order & addressing
- INT32 values are low word first (CDAB).
- Two PF sign conventions are exposed; pick the block that matches your SCADA.
- Some printed Modicon numbers are wrong; trust the hex physical address.
Network setup
- Defaults: address 1, 9600 baud, no parity, 1 stop bit.
- Terminate the master end with 120 ohm; use a repeater above 1000 m or 160 devices.
Watch out for
- Device state 5012h reports a configuration error when the phase/terminal mapping is inconsistent.

Address = 0-based wire address (the documented number is shown under it when it differs) · Order: ABCD = high word first, CDAB = low word first · Scale: engineering value = raw × scale.

Notes on this map
- Word order: the protocol states INT32/UINT32/UINT64 are LSW first with bytes MSB first, so 32-bit values are CDAB.
- PF is published twice: 002Eh-0031h signed by power direction, 0072h-0075h signed by lead/lag, with the L/C flag in 0076h-0079h.
- Functions 03, 04, 06 and 10h are supported; up to 125 registers per read.
- Left out: the INT64 energy block (0500h-0533h, Wh resolution) because the document states word order only for INT32, UINT32 and UINT64, not INT64; the duplicate by-phase table (00F6h-01B4h) and its copies of hour meters at 0534h-053Bh; input terminal mapping (1150h-1158h); display page filter settings (1600h-1629h); the factory-reset key sequence (4020h); serial-number and configurable-name ASCII registers; and the M-Bus secondary address.
- MID (PFB) versions: measuring system accepts only 0/1, CT ratio is read-only, and total-energy reset (4003h) is not available.
- On 1-phase and 2-phase systems, phase 2/3 registers read 0.
Check it against the live device. A register map tells you what the controller can expose; the unit in front of you may differ by firmware or options. Read a few registers and compare them with the unit’s own display; for a 32-bit value the float and byte-order decoder shows all four word orders at once, so a wrong word order or scale is obvious. New to this? Read what a register map is and why addresses are off by one.
Questions about the Carlo Gavazzi WM15 power analyzer
What Modbus registers does the Carlo Gavazzi WM15 power analyzer have?
This map lists 119 registers: 94 input registers, 25 holding registers. 22 of them can be written. Registers vary with firmware, options and configuration, so confirm against the device.
Are the Carlo Gavazzi WM15 power analyzer Modbus addresses 0-based or 1-based?
The manufacturer's document numbers registers Modicon 3xxxx/4xxxx (drop the prefix, subtract 1). Every address on this page is the 0-based wire address you put in the request; the documented number is shown under it where it differs. Registers are printed as a 6-digit Modicon number for function 04 (3xxxxx; use 4xxxxx for function 03) beside the hex physical address that goes in the frame; the hex address is authoritative. A few printed Modicon numbers do not match their hex address (1105h, 110Bh, 053Ah, 053Ch); the 'documented' field keeps them as printed and the wire address follows the hex.
What byte order does the Carlo Gavazzi WM15 power analyzer use for 32-bit values?
Multi-register values in this map use CDAB (low word first (word-swapped)). Set your client to this order for every 32/64-bit value in the table.
What are the minimum Modbus registers to integrate the Carlo Gavazzi WM15 power analyzer?
Start with IR 0 V L1-N (V L1-N); IR 12 A L1 (A L1); IR 40 W system (W system); IR 49 PF system (PF system); IR 51 Frequency (Frequency); IR 52 kWh(+) total (kWh(+) total); IR 78 kWh(-) total (kWh(-) total).
How do I enable Modbus control of the Carlo Gavazzi WM15 power analyzer?
Modbus RTU is on the OS (RS485) versions; OX versions have no serial port. Address, baud rate, parity and stop bits are in registers 2000h-2003h.
