Contemporary Controls Carlo Gavazzi EM24 via BASgatewayLX BACnet points list

Updated 12 November 2026

Short answer

Gateway profile for the Carlo Gavazzi EM24: 105 objects (96 AI, 6 AO, 3 BI), 51 polled by default. Inputs give voltages, currents, W, VA and VAR per phase and total, demand and peak demand, PF, frequency, total, partial, per-phase and tariff kWh/kvarh and exported energy; unpolled outputs reset the counters and peak demand.

This page lists 105 BACnet objects for the Contemporary Controls Carlo Gavazzi EM24 via BASgatewayLX — 6 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.

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 Carlo Gavazzi EM24 via BASgatewayLX and exports what it actually has to Excel — free. New to BACnet?

Questions about the Contemporary Controls Carlo Gavazzi EM24 via BASgatewayLX

How many BACnet points does the Contemporary Controls Carlo Gavazzi EM24 via BASgatewayLX have?

This list has 105 BACnet objects: 96 analog inputs, 6 analog outputs, 3 binary inputs. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Contemporary Controls Carlo Gavazzi EM24 via BASgatewayLX BACnet points are writable?

6 of the 105 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 Carlo Gavazzi EM24 via BASgatewayLX BACnet documentation?

The source is BASgatewayLX Modbus device profile Carlo_Gavazzi_EM24_Meter (Carlo_Gavazzi_EM24_Meter_LX.csv), published free by Contemporary Controls at https://www.ccontrols.com/support/dp/Carlo_Gavazzi_EM24_Meter_LX.zip.

What are the minimum BACnet points to integrate the Contemporary Controls Carlo Gavazzi EM24 via BASgatewayLX?

Start with AI 21 W Total (Total active power); AI 35 KWh(+) TOT (Imported active energy (kWh+)); AI 50 KWh(-) TOT (Exported active energy (kWh-)); AI 24 DMD W Total (Active power demand); AI 19 V L-N Total (System line-neutral voltage); AI 7 A L1 (Current L1); AI 29 PF Total (Total power factor); AI 31 Hz (Frequency).

How do I check these points on the real Carlo Gavazzi EM24 via BASgatewayLX?

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.
