Rockwell Automation (Allen-Bradley) PowerFlex 750-Series 20-750-BNETIP BACnet/IP option module BACnet points list

Updated 11 November 2026Unofficial source

Short answer

The 20-750-BNETIP option module serves a fixed object set from a PowerFlex 753 or 755 over BACnet IP: drive status and commands as Binary Values, references, measurements, fault history and eight parameter mailboxes as Analog Values, plus a few I/O terminal objects that exist on the 753 only.

This page lists 55 BACnet objects for the Rockwell Automation (Allen-Bradley) PowerFlex 750-Series 20-750-BNETIP BACnet/IP option module — 34 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from a copy of Rockwell Automation (Allen-Bradley)’s documentation hosted by archive.org, not by Rockwell Automation (Allen-Bradley) itself, so treat it as unofficial.

BMS integration notes: Rockwell Automation (Allen-Bradley) PowerFlex 750-Series 20-750-BNETIP BACnet/IP option module

Integration in brief

Write a % speed reference to AV 0 (the manual's basic-control steps) and start/stop with BV 10; BV 12 picks reference 2. Read BV 1, AV 2, AV 3, BV 3 and the fault codes for monitoring; BV 13 clears faults.

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	Run/stop command (1 = run)	Write
AV 0	Speed Reference A	Speed reference (basic-control reference, %)	Write
BV 13	Clear Faults	Fault reset (write 1)	Write
BV 1	Active	Running status	Read
AV 2	Output Frequency (Hz)	Output frequency, Hz	Read
AV 3	Output Current (Amps)	Output current, A	Read
BV 3	Fault	Drive fault	Read
AV 12	Fault 1	Latest fault code	Read

Enable & remote start

The drive's speed reference and start sources must be assigned to the option module's port; BV 10 then starts and stops the drive.

Heartbeat & communication loss

Device parameter 17 [Comm Loss Time] (default 10 s, 0 disables) sets the network-loss timeout; host parameters 33 [Comm Flt Action] and 34 [Idle Flt Action] set the response (default: fault the drive).

Network setup

An IP address jumper picks the address source: on pins 2-3 (default) with parameter 16 [DHCP] disabled it uses 192.168.0.1 / 255.255.255.0; on pins 1-2 it uses DHCP or the address parameters.
Default device instance 100 (parameter 18 [Device Instnc]); reset the module after changing it.
BACnet IP UDP port is parameter 19 [Device Port], default 47808.
Read/WriteProperty(Multiple), Who-Is/I-Am and Who-Has/I-Have are supported.

Watch out for

Commands written over BACnet are volatile; after a module reset or power cycle the BMS must write them again.
The manual's basic-control steps use AV 0 'Speed Reference A' as the % reference, while AV 19/20 map to drive parameters 545/550; check which one the drive uses.
AV 6, AV 7 and AV 11 accept only 0 (reset) when written.

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 PowerFlex 750-Series 20-750-BNETIP BACnet/IP option module and exports what it actually has to Excel — free.

Questions about the Rockwell Automation (Allen-Bradley) PowerFlex 750-Series 20-750-BNETIP BACnet/IP option module

How many BACnet points does the Rockwell Automation (Allen-Bradley) PowerFlex 750-Series 20-750-BNETIP BACnet/IP option module have?

This list has 55 BACnet objects: 1 analog input, 1 analog output, 37 analog values, 3 binary inputs, 1 binary output, 12 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Rockwell Automation (Allen-Bradley) PowerFlex 750-Series 20-750-BNETIP BACnet/IP option module BACnet points are writable?

34 of the 55 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 Rockwell Automation (Allen-Bradley) PowerFlex 750-Series 20-750-BNETIP BACnet/IP option module BACnet documentation?

Rockwell Automation (Allen-Bradley) does not publish it on its own website. This list comes from PowerFlex 750-Series BACnet/IP Option Module 20-750-BNETIP User Manual (750COM-UM005B-EN-P), revision 2014-06, a copy hosted by archive.org at https://archive.org/download/manualzilla-id-5928861/5928861.pdf. Ask Rockwell Automation (Allen-Bradley) or its representative for the current revision.

What are the minimum BACnet points to integrate the Rockwell Automation (Allen-Bradley) PowerFlex 750-Series 20-750-BNETIP BACnet/IP option module?

Start with BV 10 Run/Stop (Run/stop command (1 = run)); AV 0 Speed Reference A (Speed reference (basic-control reference, %)); BV 13 Clear Faults (Fault reset (write 1)); BV 1 Active (Running status); AV 2 Output Frequency (Hz) (Output frequency, Hz); AV 3 Output Current (Amps) (Output current, A); BV 3 Fault (Drive fault); AV 12 Fault 1 (Latest fault code).

How do I enable BMS control of the Rockwell Automation (Allen-Bradley) PowerFlex 750-Series 20-750-BNETIP BACnet/IP option module?

The drive's speed reference and start sources must be assigned to the option module's port; BV 10 then starts and stops the drive.

Does the Rockwell Automation (Allen-Bradley) PowerFlex 750-Series 20-750-BNETIP BACnet/IP option module need a BACnet heartbeat or have a communication timeout?

How do I check these points on the real PowerFlex 750-Series 20-750-BNETIP BACnet/IP option module?

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.
