Danfoss Vacon 100 / 100 FLOW / 100 HVAC internal BACnet (MS/TP and IP) BACnet points list
Updated 6 November 2026
Vacon 100 family drives (now Danfoss) have BACnet MS/TP on the RS-485 terminals and BACnet IP on the Ethernet port, both built in. The object list is Binary Values for drive status, run/stop, direction, reset, stop modes and fieldbus control-word bits, and Analog Values for monitors, the speed reference (% of nominal), limits, ramps, process data, AnyParam access and the fixed control/status words.
This page lists 71 BACnet objects for the Danfoss Vacon 100 / 100 FLOW / 100 HVAC internal BACnet (MS/TP and IP) — 30 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Danfoss’s own free documentation, linked below.

BMS integration notes: Danfoss Vacon 100 / 100 FLOW / 100 HVAC internal BACnet (MS/TP and IP)
Select the BACnet protocol on RS-485 (M5.8) or Ethernet (M5.9), set the MS/TP MAC address, baud rate and instance (P5.8.3.1) or the IP settings and P5.9.3.1.3 Protocol in use = 1, and make Fieldbus the remote control place (P3.2.1). Then command BV 15 run/stop (or AV 36 control word) and AV 24 speed reference, and read BV 1, AV 1 and the fault points.
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 |
|---|---|---|---|
| BV 15 | Run/Stop CMD | Run/stop command (1 = run) | Command |
| AV 24 | Speed Reference | Speed reference, % of nominal speed | Command |
| BV 17 | Reset Fault | Resets the active fault | Command |
| BV 1 | Run/Stop State | Running status | Read |
| AV 1 | Output Frequency | Output frequency, Hz | Read |
| AV 5 | Motor Current | Motor current, A | Read |
| AV 3 | Load (power) | Motor shaft power, % | Read |
| BV 3 | Fault State | Any active drive fault | Read |
| AV 23 | Active Fault Code | Which fault is active | Read |
Enable & remote start
Make Fieldbus the remote control place (Main Menu > Parameters > Start/Stop Setup > P3.2.1 Rem. Ctrl. Place) and choose the fieldbus as the reference source (M3.3). The manual's quick test writes AV 36 control word 0 then 1 to start, AV 24 = 50 for 50 % speed, and 0 to stop.
Heartbeat & communication loss
MS/TP: P5.8.3.1.5 Communication time-out (0-65535 s, default 10, 0 = off) raises a communication error if the drive is sole master for that long. BACnet IP: P5.9.3.1.2 Communication time-out (default 0 = not used) is the longest allowed gap between UDP packets from the master; losing the Ethernet link faults at once even with 0.
Network setup
- MS/TP: P5.8.3.1.1 baud rate (1 = 9600 default, 2 = 19200, 3 = 38400, 4 = 76800), P5.8.3.1.2 autobauding, P5.8.3.1.3 MAC address 1-127 (default 1).
- P5.8.3.1.4 / P5.9.3.1.1 Instance number: 0 (default) uses a number read from the drive, shown in the monitor menu; any other value is used as is.
- BACnet IP: P5.9.1.1 IP address mode (default 1 = DHCP with AutoIP; 0 = fixed, default 192.168.0.10); P5.9.3.1.3 Protocol in use = 1 turns BACnet IP on.
- BACnet IP: P5.9.3.1.4-6 set a BBMD IP, port and time to live for foreign-device registration.
- Terminate the first and last drive on the MS/TP segment.
- PICS lists DS-RP-B, DS-RPM-B, DS-WP-B, DS-WPM-B, DM-DDB-B and DM-DOB-B; the drive is a B-ASC.
Watch out for
- BV 15 run/stop only works when the fieldbus is the active control place.
- Process data objects depend on the drive application; check the application manual before mapping them.
- BV 18-22 stop modes and BV 23/24 BusCtrl/BusRef are commandable control-word bits; leave them alone unless needed.

Integration notes
- From the Vacon 100 Internal BACnet Installation Manual DPD00091B (Danfoss AN361179477697en-000101), Tables 14-15 (PDF pp32-34).
- Fieldbus must be the remote control place (P3.2.1 Rem. Ctrl. Place) for BV 15 and AV 24 to take effect.
- BV 7-14 and AV 15-22 / AV 30-33 are process data whose meaning depends on the application.
- AV 36/AV 37 are IEEE-754 floats; binary coding works only for values without decimals.
- The control word (AV 36) uses bit 0 start/stop, bit 1 direction, bit 2 fault reset; the status word (AV 38) bit 0 ready, 1 run, 2 direction, 3 fault, 4 alarm, 5 at reference, 6 zero speed.
- High and low limits of the objects come from the drive application.
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 Vacon 100 / 100 FLOW / 100 HVAC internal BACnet (MS/TP and IP) and exports what it actually has to Excel — free.

Questions about the Danfoss Vacon 100 / 100 FLOW / 100 HVAC internal BACnet (MS/TP and IP)
How many BACnet points does the Danfoss Vacon 100 / 100 FLOW / 100 HVAC internal BACnet (MS/TP and IP) have?
This list has 71 BACnet objects: 40 analog values, 31 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Danfoss Vacon 100 / 100 FLOW / 100 HVAC internal BACnet (MS/TP and IP) BACnet points are writable?
30 of the 71 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.
Where is the official Danfoss Vacon 100 / 100 FLOW / 100 HVAC internal BACnet (MS/TP and IP) BACnet documentation?
The source is Vacon 100 AC drives, Internal BACnet Installation Manual (DPD00091B (AN361179477697en-000101)), revision 2013-06-04, published free by Danfoss at https://assets.danfoss.com/documents/277119/AN361179477697en-000101.pdf.
What are the minimum BACnet points to integrate the Danfoss Vacon 100 / 100 FLOW / 100 HVAC internal BACnet (MS/TP and IP)?
Start with BV 15 Run/Stop CMD (Run/stop command (1 = run)); AV 24 Speed Reference (Speed reference, % of nominal speed); BV 17 Reset Fault (Resets the active fault); BV 1 Run/Stop State (Running status); AV 1 Output Frequency (Output frequency, Hz); AV 5 Motor Current (Motor current, A); AV 3 Load (power) (Motor shaft power, %); BV 3 Fault State (Any active drive fault); AV 23 Active Fault Code (Which fault is active).
How do I enable BMS control of the Danfoss Vacon 100 / 100 FLOW / 100 HVAC internal BACnet (MS/TP and IP)?
Make Fieldbus the remote control place (Main Menu > Parameters > Start/Stop Setup > P3.2.1 Rem. Ctrl. Place) and choose the fieldbus as the reference source (M3.3). The manual's quick test writes AV 36 control word 0 then 1 to start, AV 24 = 50 for 50 % speed, and 0 to stop.
Does the Danfoss Vacon 100 / 100 FLOW / 100 HVAC internal BACnet (MS/TP and IP) need a BACnet heartbeat or have a communication timeout?
MS/TP: P5.8.3.1.5 Communication time-out (0-65535 s, default 10, 0 = off) raises a communication error if the drive is sole master for that long. BACnet IP: P5.9.3.1.2 Communication time-out (default 0 = not used) is the longest allowed gap between UDP packets from the master; losing the Ethernet link faults at once even with 0.
How do I check these points on the real Vacon 100 / 100 FLOW / 100 HVAC internal BACnet (MS/TP and IP)?
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.
