Veris E51H2 / E51H5 bi-directional compact power and energy meter (BACnet MS/TP) BACnet points list
Updated 12 November 2026Unofficial source
The E51H2 and E51H5 are DIN-rail three-phase meters with a BACnet MS/TP port that measure energy in both directions. Measurements are 79 Analog Inputs (net, import and export energy per quadrant and per phase, power, demand, volts, amps, power factor, frequency, pulse counts), setup is in eleven writable Analog Values, and alerts are Binary Inputs that also roll up into AI 83. The E51H5 also has three Trend_Log objects.
This page lists 104 BACnet objects for the Veris E51H2 / E51H5 bi-directional compact power and energy meter (BACnet MS/TP) — 11 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from a copy of Veris’s documentation hosted by Kele, not by Veris itself, so treat it as unofficial.

BMS integration notes: Veris E51H2 / E51H5 bi-directional compact power and energy meter (BACnet MS/TP)
Set the MS/TP address, baud and device ID on the meter screens, then set system type (AV 2), CT size (AV 3) and system voltage (AV 6). Trend import and export energy (AI 2, AI 3) and real power (AI 11), and watch the alert BIs or AI 83.
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.

Network setup
- Device ID 1-4,193,999, set on the meter screens or via Object_Identifier; factory default is a pseudo-random number 1,000,000-3,097,151.
- Max_Master writable 1-127 (default 127); Max_Info_Frames is 1.
- Set AV 5 PT ratio before AV 6 system voltage.
Watch out for
- Writes to AVs take up to about two seconds to validate; check Reliability before reading back.
- Alerts are not latched and generate no events; poll the BIs or AI 83.
- Local date/time reset to 1 Jan 2000 on power loss; the E51H5 needs BACnet time sync for correct log timestamps.

Integration notes
- Different object list from the E50H2/E50H5 (import/export and per-quadrant objects); do not reuse an E50 map.
- Reserved objects AI 28, 77, 79, 80 and BI 8 are left out.
- BI 5 and BI 6 are printed with the name Current_Error_A; kept as printed. AI 29/30 use the E51H5 names; on the E51H2 AI 29 is Pulse Count and AI 30 is reserved.
- kVARh and kVAh objects report kWh in their Units property because BACnet has no such unit.
- AV 2 System_Type: 10 single-phase A+N, 11 single-phase A+B, 12 split-phase A+B+N, 31 3-phase delta, 40 3-phase wye.
- AV 1 Config: write 30078 to clear energy, 21211 to start a demand sub-interval (sync-to-comms), 21212 to reset max demand, 16498 to clear pulse counters. E51H5 Trend_Log TL1-TL3 default to AI 2, AI 3 and AI 19.
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 E51H2 / E51H5 bi-directional compact power and energy meter (BACnet MS/TP) 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 Veris E51H2 / E51H5 bi-directional compact power and energy meter (BACnet MS/TP)
How many BACnet points does the Veris E51H2 / E51H5 bi-directional compact power and energy meter (BACnet MS/TP) have?
This list has 104 BACnet objects: 79 analog inputs, 11 analog values, 14 binary inputs. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Veris E51H2 / E51H5 bi-directional compact power and energy meter (BACnet MS/TP) BACnet points are writable?
11 of the 104 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 Veris E51H2 / E51H5 bi-directional compact power and energy meter (BACnet MS/TP) BACnet documentation?
Veris does not publish it on its own website. This list comes from E51H2, E51H5 Power Monitoring Installation Guide (ZL0109-0B), revision 2013-06, a copy hosted by Kele at https://assets.kele.com/Catalog/17%20Power%20Monitoring/PDFs/E51H2,%20E51H5%20Install%20Guide.pdf. Ask Veris or its representative for the current revision.
What are the minimum BACnet points to integrate the Veris E51H2 / E51H5 bi-directional compact power and energy meter (BACnet MS/TP)?
Start with AI 2 KWh_Import (Real energy import, kWh); AI 3 KWh_Export (Real energy export, kWh); AI 1 KWh_Net (Net real energy (import minus export), kWh); AI 11 KW_Total (Total real power, kW); AI 19 KW_Present_Demand (Present real power demand, kW); AI 14 PF_Total (Total power factor); AI 15 Volts_LL_Avg (Average line-line voltage); AI 17 Current_Average (Average current, A); AI 18 Frequency (Frequency, Hz); AI 83 Alarm_Bitmap (All alert bits as one number).
How do I check these points on the real E51H2 / E51H5 bi-directional compact power and energy meter (BACnet MS/TP)?
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.
