Vertiv Liebert SRC (iCOM CMS card) BACnet points list

Updated 6 November 2026

Short answer

The Liebert SRC map is read through the iCOM CMS card and repeats one block of objects per unit (device address, state, temperature, alarms and on/off / fan controls) for up to eight units.

This page lists 88 BACnet objects for the Vertiv Liebert SRC (iCOM CMS card) — 32 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Vertiv’s own free documentation, linked below.

BMS integration notes: Vertiv Liebert SRC (iCOM CMS card)

Integration in brief

Fit a Liebert iCOM CMS card (BACnet IP or MS/TP), give it a unique device instance and let it discover the unit; the objects are then created automatically. Map the on/off and setpoint objects if the BMS controls the unit, and the status, main measurements and event objects for monitoring.

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.

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 Liebert SRC (iCOM CMS card) 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 Vertiv Liebert SRC (iCOM CMS card)

How many BACnet points does the Vertiv Liebert SRC (iCOM CMS card) have?

This list has 88 BACnet objects: 24 analog values, 32 binary values, 32 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Vertiv Liebert SRC (iCOM CMS card) BACnet points are writable?

32 of the 88 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 Vertiv Liebert SRC (iCOM CMS card) BACnet documentation?

The source is Liebert IntelliSlot Modbus/BACnet Reference Guide (Modbus RTU and TCP, BACnet MSTP and IP) (SL-28170), revision 2024-04 (Rev 29), published free by Vertiv at https://www.vertiv.com/49fb41/globalassets/shared/liebert-intellislot-modbus-rtu-reference-guide-SL-28170_0.pdf.

What are the minimum BACnet points to integrate the Vertiv Liebert SRC (iCOM CMS card)?

Start with MV 102 bc01_1 (Unit 1 on/off command); MV 103 bc03_1 (Unit 1 fan speed); MV 101 bs02_1 (Unit 1 state); AV 102 bs03_1 (Unit 1 temperature); BV 101 ba01_1 (Unit 1 communication alarm); BV 104 ba04_1 (Unit 1 error).

How do I check these points on the real Liebert SRC (iCOM CMS card)?

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.
