Vertiv Liebert STS2 static transfer switch BACnet points list
Updated 6 November 2026
The Liebert STS2 static transfer switch reports to a BMS through a Liebert IntelliSlot card. Analog Values carry source and output measurements and ratings, Binary Values carry events and breaker states, and Multi-state Values carry system status, preferred source and settings.
This page lists 199 BACnet objects for the Vertiv Liebert STS2 static transfer switch — 1 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 STS2 static transfer switch
Fit a Liebert IntelliSlot BACnet card (the guide's compatibility table lists IS-WEBADPT for the STS2), give it a unique device instance and let it discover the equipment; the objects are then created automatically. Map 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.
| Object | Name | Why | Access |
|---|---|---|---|
| MV 12 | 4123_1 | Normal, warning or alarm state | Read |
| AV 90 | 4097_1_1 | Source 1 input voltage A-B | Read |
| AV 167 | 6648_1_1 | Output power (printed unit kWh) | Read |
| BV 22 | 4300_1 | Internal communication lost | Read |
Network setup
- The card needs a unique Device Instance Number; the device object represents the card, not the unit.
- The cards have no BBMD; IS-UNITY-DP and IS-IPBML support foreign device registration (BBMD address and time-to-live).
- IS-UNITY-DP adds BACnet MS/TP; IS-WEBADPT and IS-IPBML are BACnet IP only. Check the compatibility table (guide section 1.1.3) for the card your unit supports.
Watch out for
- Vertiv asks for no more than about two writes and two reads per second on average; do not rewrite setpoints continuously.
- No segmented responses: large ReadPropertyMultiple requests can fail, so split them.
- Only data the managed unit actually has is created on the card, so object counts vary by model and options.

Integration notes
- Tables 5.98, 5.99, 5.100, pdf pages 1799-1806 of the 2024 guide (printed page numbers are 4 lower).
- Object names are Vertiv data IDs (e.g. 5331_1); the description holds the guide's data label. Labels repeated for different sensors or circuits get the group name in brackets.
- Most temperature objects come in pairs: a °C object and a °F object (name ending _deg_F), usually at instance + 10000.
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 STS2 static transfer switch 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 STS2 static transfer switch
How many BACnet points does the Vertiv Liebert STS2 static transfer switch have?
This list has 199 BACnet objects: 83 analog values, 95 binary values, 21 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Vertiv Liebert STS2 static transfer switch BACnet points are writable?
1 of the 199 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 STS2 static transfer switch 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 STS2 static transfer switch?
Start with MV 12 4123_1 (Normal, warning or alarm state); AV 90 4097_1_1 (Source 1 input voltage A-B); AV 167 6648_1_1 (Output power (printed unit kWh)); BV 22 4300_1 (Internal communication lost).
How do I check these points on the real Liebert STS2 static transfer switch?
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.
