Seeking Modbus Holding Register Map for Anemoi / Magnovent HVLS Fan (Airwall V2 or Airslim)
Hi everyone,
I am working on a project integrating an Anemoi (Magnovent) HVLS fan into a Siemens S7-1200 PLC system via Modbus RTU with CB1241 module.
I have successfully established communication and can read the Input Registers (30003 - 30018).
However, I am struggling to find the correct Holding Registers for:
Target Speed (Setpoint)
Control Word (Start/Stop/Reset)
The documentation I have only covers Input Registers, leaving me to reverse-engineer the Holding Registers. I have already contacted the manufacturer for the full Modbus map, but unfortunately, I have been ghosted.
I have systematically tested the first 10 Holding Register locations (40001–40010) using small setpoint values.
Does anyone have experience with these Anemoi/HPM controllers or finding modbus registers? Are the control registers mapped to a higher offset, or is there a specific 'Unlock/Enable' sequence required before the fan accepts a speed setpoint? Any advice on how to proceed with identifying these registers would be a lifesaver.
