ABB ACH180 HVAC drive (embedded BACnet MS/TP) BACnet points list
Updated 6 November 2026
The ACH180 is ABB's compact HVAC drive with BACnet MS/TP built into its EFB terminal (X5), enabled with parameter 58.01. Its fixed object list covers relay, digital I/O and analog I/O status, run/stop, direction and permissive commands, two speed references, energy counters, fault and warning history, a process PID loop and ten user-mapped Data-IO values.
This page lists 111 BACnet objects for the ABB ACH180 HVAC drive (embedded BACnet MS/TP) — 38 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from ABB’s own free documentation, linked below.

BMS integration notes: ABB ACH180 HVAC drive (embedded BACnet MS/TP)
Set 58.01 Protocol enable = BACnet MSTP, then 58.03 node address, 58.04 baud and 58.40 Device object ID, save with 96.07 and apply with 58.06 Refresh settings. Point 20.01 Ext1 commands at Embedded fieldbus and the Ext1 frequency or speed reference (28.11 or 22.11) at EFB ref1, then command BV10 and AV16. Configure 58.14-58.16 so the drive reacts to a lost BMS.
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 10 | RUN-STOP-Command | Start/stop from the BMS | Command |
| AV 16 | Input-Reference-1 | Speed reference in % | Command |
| BV 14 | Fault-Reset-Command | Reset a tripped drive | Write |
| BV 0 | RUN-STOP-Monitor | Running status | Read |
| BV 4 | HAND-AUTO-Monitor | Shows if the panel has the drive in Hand | Read |
| AV 1 | Output-Freq | Output frequency in Hz | Read |
| AV 4 | Output-Current | Motor amps | Read |
| AV 6 | Output-Power | Drive power in kW | Read |
| BV 2 | OK-FAULT-Monitor | Any active drive fault | Read |
| MV 1 | Active-Fault-1 | Which fault is active | Read |
Enable & remote start
Set 20.01 Ext1 commands (and 20.06 Ext2) to Embedded fieldbus so BV10 starts and stops the drive; 20.21 Direction = Request lets BV11 set direction. For the reference set 28.11 Ext1 frequency ref1 = EFB ref1 (scalar mode, the default) or 22.11 Ext1 speed ref1 = EFB ref1 (vector) for AV16; ref2 / AV17 uses 28.15 or 22.18. 19.11 = EFB MCW bit 11 lets BV13 pick Ext1/Ext2. BV18 Control-Override-Command also gives BACnet control; panel HAND mode has priority.
Heartbeat & communication loss
BACnet itself has no timeout. 58.14 Communication loss action (No action, Fault, Last speed, Speed ref safe, Fault always, Warning), 58.15 Communication loss mode (Any message or Cw/Ref1/Ref2) and 58.16 Communication loss time (0-6000 s) define the reaction. Changes need a reboot or 58.06 Refresh settings.
Sensors & values from the BMS
For the process PID set its feedback and setpoint sources to the data storage parameters 40.91 / 40.92, then write AV43 LOOP-Feedback and AV42 LOOP-Setpoint. AO0 drives analog output 1 when 13.12 AO1 source = AO1 data storage, and BO0/BO5 drive RO1/DO1 when their source is an RO/DIO control word bit.
Network setup
- 58.01 Protocol enable = BACnet MSTP turns on the EFB port (terminal X5).
- 58.03 Node address and 58.04 Baud rate set the MS/TP link.
- 58.40 Device object ID sets the device instance (unique, 1-4194303); the device object's default is 4194303.
- Save with 96.07 Parameter save manually and apply with 58.06 Communication control = Refresh settings.
- 58.07-58.13 are diagnostic counters for checking the link.
Watch out for
- Panel HAND mode beats BACnet control override (BV18).
- BV39 Parameter-Save-Command writes permanent memory; use it once, not cyclically.
- Last speed and Speed ref safe keep the motor running after a comm loss; make sure that is safe.
- Fault reset through BV14 always goes through; no source parameter is needed.
- AV120-AV129 Data-IO objects only carry data after parameters 58.101-58.110 are mapped.

Integration notes
- Set the device instance with parameter 58.40 Device object ID (1-4194303); it must be unique on the network.
- Commands (BV10-BV14, AV16/AV17) only take effect when the drive's start/reference sources are set to embedded fieldbus.
- AV120-AV129 (Data-IO-1..10) carry whatever drive parameters are mapped in 58.101-58.110; Data-IO-5..10 are read-only.
- Gaps in the instance numbering are reserved by ABB and do not exist on the drive.
- MSV1-MSV3 state lists print 'Output-Phase-Loss Motor-Stall' without a comma; split here into two states, numbered 1..n in printed order.
- Loop objects (LOOP0/LOOP1) point at AV44 output, AV43 feedback and AV42 setpoint.
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 ACH180 HVAC drive (embedded BACnet MS/TP) and exports what it actually has to Excel — free.

Questions about the ABB ACH180 HVAC drive (embedded BACnet MS/TP)
How many BACnet points does the ABB ACH180 HVAC drive (embedded BACnet MS/TP) have?
This list has 111 BACnet objects: 2 analog inputs, 1 analog output, 55 analog values, 7 binary inputs, 2 binary outputs, 35 binary values, 2 loops, 7 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which ABB ACH180 HVAC drive (embedded BACnet MS/TP) BACnet points are writable?
38 of the 111 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 ABB ACH180 HVAC drive (embedded BACnet MS/TP) BACnet documentation?
The source is ACH180 HVAC control program Firmware manual (3AXD50000955893 Rev B), revision 2024-03-28, published free by ABB at https://library.e.abb.com/public/f3d8d50ec8db4a54baecad8c3ec97ca1/EN_ACH180_FW_B_A5.pdf.
What are the minimum BACnet points to integrate the ABB ACH180 HVAC drive (embedded BACnet MS/TP)?
Start with BV 10 RUN-STOP-Command (Start/stop from the BMS); AV 16 Input-Reference-1 (Speed reference in %); BV 14 Fault-Reset-Command (Reset a tripped drive); BV 0 RUN-STOP-Monitor (Running status); BV 4 HAND-AUTO-Monitor (Shows if the panel has the drive in Hand); AV 1 Output-Freq (Output frequency in Hz); AV 4 Output-Current (Motor amps); AV 6 Output-Power (Drive power in kW); BV 2 OK-FAULT-Monitor (Any active drive fault); MV 1 Active-Fault-1 (Which fault is active).
How do I enable BMS control of the ABB ACH180 HVAC drive (embedded BACnet MS/TP)?
Set 20.01 Ext1 commands (and 20.06 Ext2) to Embedded fieldbus so BV10 starts and stops the drive; 20.21 Direction = Request lets BV11 set direction. For the reference set 28.11 Ext1 frequency ref1 = EFB ref1 (scalar mode, the default) or 22.11 Ext1 speed ref1 = EFB ref1 (vector) for AV16; ref2 / AV17 uses 28.15 or 22.18. 19.11 = EFB MCW bit 11 lets BV13 pick Ext1/Ext2. BV18 Control-Override-Command also gives BACnet control; panel HAND mode has priority.
Does the ABB ACH180 HVAC drive (embedded BACnet MS/TP) need a BACnet heartbeat or have a communication timeout?
BACnet itself has no timeout. 58.14 Communication loss action (No action, Fault, Last speed, Speed ref safe, Fault always, Warning), 58.15 Communication loss mode (Any message or Cw/Ref1/Ref2) and 58.16 Communication loss time (0-6000 s) define the reaction. Changes need a reboot or 58.06 Refresh settings.
Can the BMS supply sensor values to the ABB ACH180 HVAC drive (embedded BACnet MS/TP)?
For the process PID set its feedback and setpoint sources to the data storage parameters 40.91 / 40.92, then write AV43 LOOP-Feedback and AV42 LOOP-Setpoint. AO0 drives analog output 1 when 13.12 AO1 source = AO1 data storage, and BO0/BO5 drive RO1/DO1 when their source is an RO/DIO control word bit.
How do I check these points on the real ACH180 HVAC drive (embedded BACnet MS/TP)?
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.
