Socomec DIRIS Digiware M-50 / M-70 BACnet IP gateway (per-load measurement objects) BACnet points list
Updated 12 November 2026Unofficial source
The DIRIS Digiware M-50 / M-70 is a BACnet IP gateway for Socomec metering. Each downstream device appears as its own BACnet device (instance 100 + its Modbus address) with Analog Input objects per load: voltages, currents, unbalance, active, reactive and apparent power and power factor per phase and total, load-curve values, THD and energy counters. The object number is the load number times 100 plus a fixed measurement index (0-61); this list shows load 1.
This page lists 62 BACnet objects for the Socomec DIRIS Digiware M-50 / M-70 BACnet IP gateway (per-load measurement objects) — 0 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from a copy of Socomec’s documentation hosted by Instrumentation2000, not by Socomec itself, so treat it as unofficial.

BMS integration notes: Socomec DIRIS Digiware M-50 / M-70 BACnet IP gateway (per-load measurement objects)
Discover one BACnet device per metered device (instance 100 + Modbus address) behind the gateway, then read the per-load Analog Inputs: total power, energy, current, voltage and power factor. All values are read-only.
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.

Enable & remote start
BACnet IP is switched on in Easy Config System or the web server (BACnet activation).
Network setup
- Main instance ID defaults to 100 and must be unique; a virtual network ID must also be set and be unique.
- UDP port is fixed at 47808.
- The PICS is on socomec.com.
Watch out for
- Object numbers repeat per load: load 2 adds 100 to every instance.
- Unsupported measurements read 0, not an error.

Integration notes
- Only the index table is printed. Instance = load number x 100 + index (load 1 = AI 100-161, load 2 = AI 200-261 and so on); load 1 is listed here.
- Device instances: the gateway itself is the main instance (default 100); a downstream device with Modbus address xx is device 100 + xx.
- A device returns 0 for measurements it does not support (for example THD on a DIRIS Digiware I-30).
- The manual also mentions Binary Input and Binary Output objects (auxiliary contacts, IO-10 outputs) but gives no table for them; they are not listed.
- The guide gives no read/write column; all listed measurement objects are read-only values.
- Copied from a distributor-hosted copy of the Socomec manual; socomec.com blocks automated downloads.
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 DIRIS Digiware M-50 / M-70 BACnet IP gateway (per-load measurement objects) and exports what it actually has to Excel — free.

Questions about the Socomec DIRIS Digiware M-50 / M-70 BACnet IP gateway (per-load measurement objects)
How many BACnet points does the Socomec DIRIS Digiware M-50 / M-70 BACnet IP gateway (per-load measurement objects) have?
This list has 62 BACnet objects: 62 analog inputs. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Socomec DIRIS Digiware M-50 / M-70 BACnet IP gateway (per-load measurement objects) BACnet points are writable?
None of the listed objects are marked writable in the source documentation. The source has no read/write column, so this is inferred from object type.
Where is the official Socomec DIRIS Digiware M-50 / M-70 BACnet IP gateway (per-load measurement objects) BACnet documentation?
Socomec does not publish it on its own website. This list comes from DIRIS Digiware M-50 / M-70 instruction manual, Annex B BACnet communication (548751D), a copy hosted by Instrumentation2000 at https://www.instrumentation2000.com//media/pdf/socomec-m-50-m-70-manual.pdf. Ask Socomec or its representative for the current revision.
What are the minimum BACnet points to integrate the Socomec DIRIS Digiware M-50 / M-70 BACnet IP gateway (per-load measurement objects)?
Start with AI 121 TotalPowerActive (Total active power, W (load 1)); AI 156 A+ (Imported active energy, Wh (load 1)); AI 102 CurrentSyst (System current, A (load 1)); AI 100 VystPhN (System phase-neutral voltage, V (load 1)); AI 124 TotalPowerFactor (Total power factor (load 1)); AI 103 Frequency (Frequency, Hz (load 1)).
How do I enable BMS control of the Socomec DIRIS Digiware M-50 / M-70 BACnet IP gateway (per-load measurement objects)?
BACnet IP is switched on in Easy Config System or the web server (BACnet activation).
How do I check these points on the real DIRIS Digiware M-50 / M-70 BACnet IP gateway (per-load measurement objects)?
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.
