ACS now offers the EBM Papst CN1116 Modbus Display & Control (MDC) and DSP1000 HMI touchscreen interface, enabling engineers and facilities managers to monitor, commission, and control EC fan systems with clarity and precision. These HMI solutions streamline feedback, diagnostics, and configuration for EC fan networks.


Why EBM Papst HMI Solutions Stand Out

  • Provide real-time visual feedback on fan status, setpoints, or alarms.

  • Local commissioning ease via keypad and display, reducing configuration errors.
  • Auto fan addressing and diagnostics simplify setup and maintenance.

  • Direct integration within EC fan ecosystems, avoiding third-party controller compatibility issues. ebmpapst.comebmpapst.comfr.farnell.com

Product Insights & Benefits

CN1116 Modbus Display & Control (MDC)

The CN1116 serves as a dual RS485 Modbus interface: one port connects to EC fans (master), the other integrates with higher-level systems like BMS or IoT gateways (slave). It includes a keypad and display for manual menu navigation, status monitoring, and mode selection. ebmpapst.com+2ebmpapst.com+2

The CN1116 Modbus display and control unit, showing a healthy fan status with real-time data including a speed of 1200 RPM and power consumption of 260W.

Key Benefits:

  • Up to 100 fans supported on the master Modbus bus.

  • Auto fan addressing accelerates commissioning.

  • Multiple operating modes: Monitor, Monitor & Control, Constant Volume/Pressure, Modbus Relay.

  • Local visibility of fan data, such as RPM, current set value, and alarms—ideal for service teams.

  • Supports 9–57 V DC supply, wall‑mountable, user-accessible panel. ManualsLib+13ebmpapst.com+13ebmpapst.com+13fr.farnell.com+2ManualsLib+2

Use Cases:

  • Fan array commissioning in AHUs and HVAC systems.

  • Local troubleshooting and diagnostics.

  • Small‑scale installations where BMS feedback lines are needed without full automation.

Why It's Preferred:

Competitors may require laptop interfaces or lack integrated control modes. The CN1116 offers out‑of‑box visibility, control modes, and integration with EC‑Control firmware—all within a compact, field‑mature unit.


DSP1000 HMI Touchscreen Display

The DSP1000 is a sleek HMI touchscreen interface designed for use with CN1127 and CN1133 connectivity modules. It allows intuitive touchscreen control of EC fan parameters, setpoints, and fan status without accessing a laptop or web interface.

Highlights:

  • Capacitive colour touchscreen with responsive GUI.

  • Live visualisation of fan network data, alarms, and system modes.

  • Ideal for control-room environments and service interfaces.

  • Fast navigation between real-time analytics screens and commissioning tools.

Applications:

  • Permanent or portable panels in plant rooms showing system status.

  • User-accessible control interface in installations with multiple fan sections.

  • Site monitoring where central UI is preferred over individual web login.

Competitive Advantage:

Very few competing HMIs integrate natively with EBM Papst MMCUs. The DSP1000’s seamless connectivity over RS485 and touchscreen control simplifies operation and eliminates compatibility issues common with third-party devices.

Shared Advantages of These Interfaces

  • Display and navigate through modes like monitor-only or constant pressure control.

  • Support EBM Papst's auto-addressing features to save installation time. ManualsLibebmpapst.comfr.farnell.com+1ebmpapst.com+2fr.farnell.com+2

  • Provide local control and diagnostics without dependency on external devices or cloud access.

  • Use standard power input (9–57 V DC), compact enclosures suitable for technical areas.

  • Designed exclusively for compatibility with EBM Papst networked EC fans and modules.


Installation & Integration Tips

  1. Mount the CN1116 or DSP1000 in easy to access panel or wall position.

  2. Supply 9–57 V DC power using a safe low-voltage supply.

  3. Wire RS485 master to fan network; slave port optional for BMS or IoT module connection.

  4. Start auto-address routine to detect connected fans and assign IDs.

  5. Navigate operation modes via keypad or touchscreen, configure thresholds or setpoints on-site.

  6. Use display for fault history, runtime insight, and real-time measurement.
