Contemporary Controls ABB ACH550 (DCU profile, 5305 = 1) via BASgatewayLX BACnet points list

Updated 12 November 2026

Short answer

Gateway profile for the ABB ACH550 when its embedded fieldbus uses the DCU control profile: 609 objects (546 AI, 4 AO, 59 BI), 138 polled by default. Coil and status bits (STOP, START, RUNNING, FAULT, ALARM), the 16- and 32-bit control/status words, the actual signals and the whole parameter list are mapped. Four Analog Outputs write the control words and the two references.

This page lists 609 BACnet objects for the Contemporary Controls ABB ACH550 (DCU profile, 5305 = 1) via BASgatewayLX — 4 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Contemporary Controls’s own free documentation, linked below.

BMS integration notes: Contemporary Controls ABB ACH550 (DCU profile, 5305 = 1) via BASgatewayLX

Integration in brief

Set the drive for fieldbus control (EXT1 commands and reference = COMM) and 5305 = 1. With the DCU profile the drive takes start/stop from the ACH550 control word (AO 74, register 40031); write the speed reference to Reference 1 (AO 63). Read RUNNING, FAULT, ALARM and the actual values.

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.

Enable & remote start

Set EXT1 commands (parameter 1001) to 10 (COMM) and the speed reference source to COMM as the ACH550 manual describes, and parameter 5305 = 1. In this mode start/stop comes from register 40031 (AO 74), not 40001.

Object ID lookup: Contemporary Controls BASgatewayLX ABB ACH550 DCU point IDs by name

Integration notes

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 ABB ACH550 (DCU profile, 5305 = 1) via BASgatewayLX and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.

Questions about the Contemporary Controls ABB ACH550 (DCU profile, 5305 = 1) via BASgatewayLX

How many BACnet points does the Contemporary Controls ABB ACH550 (DCU profile, 5305 = 1) via BASgatewayLX have?

This list has 609 BACnet objects: 546 analog inputs, 4 analog outputs, 59 binary inputs. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Contemporary Controls ABB ACH550 (DCU profile, 5305 = 1) via BASgatewayLX BACnet points are writable?

4 of the 609 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 Contemporary Controls ABB ACH550 (DCU profile, 5305 = 1) via BASgatewayLX BACnet documentation?
