ebm-papst BACnet Gateway ECCN02-CT0 (EC fan network) BACnet points list
Updated 6 November 2026
The ECCN02-CT0 gateway links up to 18 ebm-papst EC fans (addressed over Modbus RS-485 with EC-Control) to a BACnet IP (Ethernet, the default port) or BACnet MS/TP network. Once 'BMS Control' is switched on at the gateway and written to the fans, the BMS sets each fan's speed as a 0-100 % PWM value through one analog value per fan. The manual's BACnet table lists only these speed commands.
This page lists 18 BACnet objects for the ebm-papst BACnet Gateway ECCN02-CT0 (EC fan network) — 18 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from ebm-papst’s own free documentation, linked below.

BMS integration notes: ebm-papst BACnet Gateway ECCN02-CT0 (EC fan network)
Address the fans with EC-Control first, pick Ethernet TCP/IP (default) or MS/TP under Settings > BMS Config > Comm. Settings, set the IP or MS/TP parameters and reboot. Turn BMS MASTER on under Settings > BMS Config > BMS Control and write the values to the fans; then write each fan's PWM AV.
Minimum points to map
The short list most integrators start with — enough to run the unit from a BMS. Map more as the job needs.
| Object | Name | Why | Access |
|---|---|---|---|
| AV 180 | BAV0_FAN_1_BMS_PWM | Fan 1 speed command, 0-100 % | Write |
| AV 181 | BAV0_FAN_1_BMS_PWM | Fan 2 speed command, 0-100 % | Write |
Enable & remote start
BMS control is switched on at the gateway (Settings > BMS Config > BMS Control > BMS MASTER = ON), then written into the fans with WRITE VALUES = YES. The fans then ignore their 0-10 V analog input and take the %PWM written over BACnet.
Network setup
- BACnet IP is active by default: IP 10.0.0.100, mask 255.255.255.0, UDP port 47808 (0xBAC0); set under IP SETTINGS, then REBOOT.
- MS/TP defaults: device instance 47000, baud 19200, MAC 1, parity 8E1; change them under MSTP SETTINGS and REBOOT the gateway.
- The gateway does not address fans itself; program each fan's Modbus address with EC-Control before setup.
- Address the fans (ebm-papst suggests starting at 2, up to 18) and enable them in the gateway before connecting them over RS-485.
Watch out for
- With BMS control on, the fans' EEPROM set value is deactivated and the analog input is ignored.
- A reboot is needed for a new device instance to take effect.
- Duplicate object names in the table: map by instance, not name.
ebm-papst BACnet Gateway ECCN02-CT0 (EC fan network) BACnet objects
Type: AI, AO, AV, BI, BO, BV, MI/MO/MV (multi-state) · Access: Read read-only, Write writable, Command writable with a priority array.
Note: the source document has no read/write column, so access here is inferred from the object type (inputs read-only, values writable). Confirm on the live controller before writing.

Integration notes
- Section 6.4.1 of the manual lists AV 180-197 for the ECCN02-CT0; the other gateway model uses a different instance range.
- Object names are printed with typos (FAN_1 appears twice, FAN_11 is missing); they are kept as printed. Instance order follows fan number.
- The table has no read/write column; the objects are BMS speed commands, so they are shown writable.
- Fan monitoring points are not in this manual.
- Source: section 6.4 'BACnet Variable for PWM Input', manual page 22 (18 objects).
Check it against the live device. A points list tells you what the controller can expose; the unit in front of you may differ by firmware or installed options. This list is provided as-is for reference only and may contain mistakes — confirming it before you write, map or commission anything is up to you (terms). Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the BACnet Gateway ECCN02-CT0 (EC fan network) and exports what it actually has to Excel — free.

Questions about the ebm-papst BACnet Gateway ECCN02-CT0 (EC fan network)
How many BACnet points does the ebm-papst BACnet Gateway ECCN02-CT0 (EC fan network) have?
This list has 18 BACnet objects: 18 analog values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which ebm-papst BACnet Gateway ECCN02-CT0 (EC fan network) BACnet points are writable?
18 of the 18 objects accept a write. Points marked Command have a priority array: a write holds until it is released, so release it back to automatic when you are done. The source has no read/write column, so this is inferred from object type.
Where is the official ebm-papst BACnet Gateway ECCN02-CT0 (EC fan network) BACnet documentation?
The source is BACnet Gateway Manual - User Manual for ECCN02-CT0, ECCN06-CT0 (Version 1.0), revision 2021-01-28, published free by ebm-papst at https://www.ebmpapst.com/content/dam/ebm-papst/loc/apac/australia/operating-instructions/eccn-2---6/ECCN02_ECCN06_Manual.pdf.
What are the minimum BACnet points to integrate the ebm-papst BACnet Gateway ECCN02-CT0 (EC fan network)?
Start with AV 180 BAV0_FAN_1_BMS_PWM (Fan 1 speed command, 0-100 %); AV 181 BAV0_FAN_1_BMS_PWM (Fan 2 speed command, 0-100 %).
How do I enable BMS control of the ebm-papst BACnet Gateway ECCN02-CT0 (EC fan network)?
BMS control is switched on at the gateway (Settings > BMS Config > BMS Control > BMS MASTER = ON), then written into the fans with WRITE VALUES = YES. The fans then ignore their 0-10 V analog input and take the %PWM written over BACnet.
How do I check these points on the real BACnet Gateway ECCN02-CT0 (EC fan network)?
Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
