BMS integration notes: Functional Devices PSH600-UPS-BC / PSH550-UPS-BC UPS power supply
Read-only device: poll BI1 for on-battery, BI2 for battery present, and AI3/AI4 for remaining capacity and run time.
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 |
|---|---|---|---|
| BI 1 | BI1 | On battery when 1 (UPS) | Read |
| BI 2 | BI2 | Battery connected | Read |
| AI 3 | AI3 | Battery capacity, % | Read |
| AI 4 | AI4 | Battery time remaining, min | Read |
| AI 1 | AI1 | Load, % | Read |
Network setup
- The PICS prints the device object ID default as DE277000 (vendor ID 277); it is writable.
- MS/TP master; baud rates are listed in the PICS. Max_Master defaults to 127.

Object ID lookup: Functional Devices PSH600-UPS-BC / PSH550-UPS-BC UPS power supply point IDs by name
Integration notes
- Object names are user-writable and the PICS prints no factory default name, so each object is listed by its printed ID (BI1, AI1...). Names are limited to 4 characters.
- The PSH550-UPS-BC PICS (v1.9, 8 Nov 2016) prints the same six objects; only the AI2 range differs (0-550 VA vs 0-600 VA).
- AI meanings come from each object's Device_Type text (UPS Percent Load, VA Load, UPS Batt Capacity, Time Remaining).
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 PSH600-UPS-BC / PSH550-UPS-BC UPS power supply and exports what it actually has to Excel — free.
