Monitor and control a whole bank of ebm-papst EC fans over Modbus RTU on one live dashboard — speed, motor status and power for every fan, without a BMS or a SCADA project. Download the free 16-fan demo workspace, open it in ModbusManager Pro, and explore it with the built-in simulator or your real fans. The same dashboard works with any Modbus device.
Demo: 16-fan Pro workspace · runs on the built-in simulator or real fans · Modbus RTU
ebm-papst EC fans ship with Modbus RTU built in — every fan reports its actual speed, motor status, power draw and module temperature, and accepts a speed setpoint. This demo turns a bank of sixteen such fans into a single operator dashboard.
ModbusManager Pro polls all 16 fans, and a small Structured Text script flags each fan green when its status word is healthy (0) and red on any fault. Speed shows on a fan widget, power as a live value, status on a lamp — sixteen times over, on one page.
No building-management system, no SCADA server, no per-point licensing. One PC on the RS-485 line — or the built-in simulator if you have no fans on the bench yet.
16 × ebm-papst EC fan (Modbus RTU, 19200 8E1) → USB–RS485 adapter → ModbusManager Pro dashboard on Windows. Up to 247 fans on one bus.
One download: a ready-made ModbusManager Pro workspace with sixteen fans pre-mapped to the ebm-papst register layout, the motor-status script, and a finished dashboard page. Open it, point it at the simulator or your fans, and you have a live fan wall.
Needs ModbusManager Pro (14-day trial works). No hardware required — the built-in slave simulator can stand in for the fans.
ebm-papst uses decimal register addresses. The demo reads the feedback block (D010–D021) as input registers with function code 04; the speed setpoint is a holding register written with function code 06.
| Addr | Value | Access | Range / scale | Unit |
|---|---|---|---|---|
| 53264 (D010) | Actual speed | FC04 read | 0–65535 = 0–100% | % |
| 53265 (D011) | Motor status (0 = OK) | FC04 read | bitfield | — |
| 53269 (D015) | Module temperature | FC04 read | signed | °C |
| 53281 (D021) | Current power | FC04 read | ÷1 | W |
| 53249 (D001) | Speed setpoint | FC06 write | 0–65535 = 0–100% | % |
For a fan wall, an air-handling unit or a test bench, a full BMS or SCADA setup is overkill. ModbusManager Pro gives you a clean operator dashboard for a one-time 119 USD license — no runtime fees, no per-point pricing, no server to maintain.
Because it speaks plain Modbus, it is not tied to ebm-papst. Put EC fans, an energy meter, a VFD and a temperature controller on the same screen, whatever the brand.
HVAC and ventilation commissioning, fan-wall and AHU monitoring, cleanroom and data-centre cooling, OEM test benches, and anyone running several Modbus EC fans who wants one live view without a BMS.
Fan arrays are the classic case: sixteen EC fans on one RS-485 line, each with its own speed setpoint and status registers. ModbusManager Pro can collect every fan’s speed, status and temperature into one register map, and write setpoints back to individual fans from a shared block — so the PLC or BMS addresses the array as one device instead of sixteen.
