ABB ACH580 E-Clipse and packaged bypass (bypass BACnet objects) BACnet points list
Updated 6 November 2026
The E-Clipse bypass has its own controller with an embedded BACnet MS/TP port. Its objects cover bypass relay and digital I/O status, system run, fault, warning and mode flags, start/stop, override, permissive, interlock and reset commands, and current, voltage, energy and run-time values. With bypass parameter 1625 COMM CTL = SYSTEM, start/stop and interlocks go through these bypass objects instead of the drive's.
This page lists 54 BACnet objects for the ABB ACH580 E-Clipse and packaged bypass (bypass BACnet objects) — 22 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 ACH580 E-Clipse and packaged bypass (bypass BACnet objects)
Set 9802 COMM PROT SEL = BACNET (5). The bypass is its own MS/TP node: give it a unique MAC in 5003 (default 256 keeps it off the network) and a device instance in 5040/5099. Then set 1625 COMM CTL = SYSTEM and 1601 = COMM, command BV10 and read BV0, BV3, BV4 and AV0.
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 CMD | System run / stop command | Command |
| BV 12 | RUN PERMISSIVE CMD | Run permissive command | Command |
| BV 14 | FAULT RESET | Reset a bypass fault | Command |
| BV 0 | SYS RUN ACT | System running | Read |
| BV 4 | SYSTEM MODE | Motor on bypass or drive | Read |
| AV 1 | BYPASS MODE | Hand / off / auto: 0 off, 1 hand, 2 auto | Read |
| AV 0 | CURRENT | Output current, A | Read |
| BV 3 | SYS FLT ACT | System fault | Read |
| AV 3 | LAST FLT | Last bypass fault code | Read |
Enable & remote start
Bypass parameter 1625 COMM CTL = (1) SYSTEM makes the bypass objects the control path; 1601 = COMM is needed for BV10 run/stop and 1701 = COMM for BV11 override. BV20 CTL OVERRIDE CMD puts the bypass in BACnet control override; panel HAND mode still has priority.
Heartbeat & communication loss
Bypass parameters 3004 COMM LOSS (action) and 3005 COMM TIME (timeout) set the reaction to lost communication; fault 3028 EXT COMM LOSS shows when the BMS does not poll within 3005.
Network setup
- 9802 COMM PROT SEL = BACNET (5) turns on the shared EIA-485 port; baud (5804) and parity (5805) in group 58 apply to both the drive and bypass nodes.
- Bypass node: MS/TP MAC in 5003 (default 256 = not visible on the network; set a unique value 1-127 to use the bypass objects). Setting 5003 to 0 holds the channel in reset.
- Bypass device instance = 5040 (lower word) + 5099 (upper word).
- The drive node is set separately in group 58 (MAC 5803, device instance 5840/5899); drive and bypass addresses must be unique.
- After changing communication settings, cycle power or set the station ID to 0 and back.
- Only the Device object name is writable; set it from the BMS so it is unique.
Watch out for
- BV10-BV18 do nothing while 1625 COMM CTL = DRIVE ONLY.
- Panel HAND mode beats BACnet control override (BV20).
- Bypass MS/TP token counter 5013 should keep rising when communication is healthy.

Integration notes
- The drive's own objects (manual pp135-144) follow the ACH580 drive list and are in the separate ACH580 entry.
- With 1625 COMM CTL = DRIVE ONLY, bypass objects BV10-BV18 are not valid and the drive objects are used; with 1625 = SYSTEM the drive's control objects are not available.
- Commands need their bypass source parameter set to COMM: 1601 for BV10 run/stop, 1602 BV12 permissive, 1607 BV14 reset, 1603-1606 BV15-BV18 interlocks, 1701 BV11 override; relay outputs BO0-BO4 need 1401/1404/1407/1410/1413.
- AV12 is printed with the name 'C-B VOLT' but described as phase C - phase A voltage; kept as printed.
- AV5 WARNING WORD 2 is described in the manual as the 'first' warning word, apparently a copy error.
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 ACH580 E-Clipse and packaged bypass (bypass BACnet objects) and exports what it actually has to Excel — free.

Questions about the ABB ACH580 E-Clipse and packaged bypass (bypass BACnet objects)
How many BACnet points does the ABB ACH580 E-Clipse and packaged bypass (bypass BACnet objects) have?
This list has 54 BACnet objects: 15 analog values, 11 binary inputs, 5 binary outputs, 23 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which ABB ACH580 E-Clipse and packaged bypass (bypass BACnet objects) BACnet points are writable?
22 of the 54 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 ACH580 E-Clipse and packaged bypass (bypass BACnet objects) BACnet documentation?
The source is ACH580 E-Clipse and Packaged Bypass User/Hardware Manual, US (3AXD50000289554 Rev C), published free by ABB at https://library.e.abb.com/public/a8d8ce51a16e4deab6469e1d15bd7171/3AXD50000289554_en_C_ACH580%20E-Clipse%20and%20Packaged%20Bypass%20Hardware%20Manual%2C%20US.pdf.
What are the minimum BACnet points to integrate the ABB ACH580 E-Clipse and packaged bypass (bypass BACnet objects)?
Start with BV 10 RUN/STOP CMD (System run / stop command); BV 12 RUN PERMISSIVE CMD (Run permissive command); BV 14 FAULT RESET (Reset a bypass fault); BV 0 SYS RUN ACT (System running); BV 4 SYSTEM MODE (Motor on bypass or drive); AV 1 BYPASS MODE (Hand / off / auto: 0 off, 1 hand, 2 auto); AV 0 CURRENT (Output current, A); BV 3 SYS FLT ACT (System fault); AV 3 LAST FLT (Last bypass fault code).
How do I enable BMS control of the ABB ACH580 E-Clipse and packaged bypass (bypass BACnet objects)?
Bypass parameter 1625 COMM CTL = (1) SYSTEM makes the bypass objects the control path; 1601 = COMM is needed for BV10 run/stop and 1701 = COMM for BV11 override. BV20 CTL OVERRIDE CMD puts the bypass in BACnet control override; panel HAND mode still has priority.
Does the ABB ACH580 E-Clipse and packaged bypass (bypass BACnet objects) need a BACnet heartbeat or have a communication timeout?
Bypass parameters 3004 COMM LOSS (action) and 3005 COMM TIME (timeout) set the reaction to lost communication; fault 3028 EXT COMM LOSS shows when the BMS does not poll within 3005.
How do I check these points on the real ACH580 E-Clipse and packaged bypass (bypass BACnet objects)?
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.
