HWg-PWR 3/12/25: Passerelle M-Bus Intelligente pour la gestion de l’énergie

HWg-PWR est un équipement réseau conçu pour la gestion de compteurs d’énergies M-Bus. Il supporte jusqu’ à 3,12 ou 25 équipements M-Bus (eau, gaz, électricité, chaleur).

Note: Shorted version - full details in english version.

HWg-PWR peut gérer les données de 3/12/25 compteurs M-Bus. Il peut, tout en gérant les relevés de consommation d’énergie, envoyer des alertes (e-mails, Trap SNMP) sur dépassement de seuils.

Toutes les valeurs sont accessibles via protocoles SNMP, Modbus/TCP, ou depuis une interface Web.

HWg-PWR 3/12/25 sait travailler seul, la mise en place d’un serveur local n’est pas nécessaire. Les tableaux sont affichés sur l’interface Web, et un rapport de consommation peut être expédié régulièrement (jour, semaine, mois).

Avec le HWg-PWR 3/12/25, il est très pratique de créer un système de gestion de l’énergie. Les utilisations typiques concernent la gestion des Data Center, des centres commerciaux, locaux industriels ou immeubles de bureaux.

Advantages of using third-party M-Bus meters

  • Vast range of meters with the EN 13757 (M-Bus) interface to choose from.
    It is easy to use special-purpose meters (non-standard form factor or measured range, e.g. indirect electricity meters rated up to 1000 A).
  • M-Bus meters frequently provide extended information (total consumption and immediate values, voltage at different phases, power factor, etc...).
  • Values from certified meters can be used for billing purposes.

M-Bus or S0 pulse counter

S0 is a legacy system of counting pulses that correspond to a certain amount of energy.
The M-Bus interface is the current standard for energy metering. Unlike pulse counting (S0), it works with absolute values (that can be used for customer billing). In addition, M-Bus provides more values, such as the immediate current and voltage, cos φ, and so on.

An S0 to M-Bus converter can be used to connect S0 devices:

Caution: We recommend to always check and test what values does the manufacturer guarantee at the M-Bus interface.

Applications

  • Remote monitoring of electricity meters in small server rooms and BTS
  • Monitoring of energy consumption in rented premises
  • Reading out energy consumption in remote or inaccessible areas
  • Control over energy costs
  • Checking for individual line overloads in three-phase wirings
  • Checking for undervoltage in electric wirings
  • Monitoring the flow of liquids

Collecting data from 1 to 25 M-Bus electricity meters

  • Various energy meters (equipped with the M-Bus interface) are connected to the HWg-PWR unit.
  • All values are available to external software over LAN and SNMP.
  • Energy consumption details can be viewed using the Web interface or an iPhone or Android app.

Server room: Energy consumption monitoring + phase outage detection

  • Up to 25 electricity meters measure the single-phase or three-phase consumption of the cabinets.
  • Up to 8 inputs can detect phase outages.
  • When a phase fails, a warning can be e-mailed.
  • Upon an alarm (phase failure or current out of range), a text message alert can be sent to a mobile phone via an external SMS Gateway.
  • Energy consumption data can be connected to any SCADA system (Modbus/TCP) or accessed over SNMP.

Measuring energy consumption with S0 pulses and M-Bus meters

  • Modern electricity meters with the M-Bus interface can be connected to HWg-PWR directly.
  • Older electricity meters with a S0 pulse output can be connected using a “S0-M-Bus” converter.
  • Current consumption charts are available through the HWg-PWR web interface.
  • Every day, week or month, HWg-PWR e-mails a report. The e-mail contains a billing statement including KWh and a conversion to currency.
  • When the current consumption exceeds or drops below a set threshold, the unit sends an e-mail alert.

Remote energy metering with a central WEB portal

  • Various energy meters are connected to a single HWg-PWR unit.
  • Each unit has a WEB interface for configuration, viewing logs, etc.
  • All consumption data are uploaded to a central portal using the HWg-Push protocol.
  • The central portal (e.g. SensDesk) generates detailed analyses and statistics concerning energy consumption.

  • What values can HWg-PWR display?
    HWg-PWR can display any values and quantities that are accessible over M-BUS from the respective meter.
  • Is it necessary to use meters supplied by HW group?
    No. Any device from any (third-party) manufacturer can be connected to HWg-PWR, as long as it has the M-Bus interface.
    To help you choose, we have compiled a list of tested meters. See the link in the Download box.
  • How many devices / values can be connected at once?
    The M-Bus supports up to 250 connected units. HWg-PWR supports a maximum of 3 / 12 / 25 devices.
  • How many different variables can be monitored?
    HWg-PWR 3 / 12 / 25 supports a maximum of 100 variables. The particular combination is not relevant, e.g. 25x4 (25 meters x 4 variables each) or 10x10 variables are possible.
    Each variable can be logged and monitored by e-mail.
  • Is it possible to use electricity, water and gas meters from different manufacturers on a single bus?
    Yes, as long as the devices use the same communication speed (typically 2400 b/s)
  • How far away can be the M-Bus meters from the HWg-PWR unit?
    At 300 Bd, the cable segment length must not exceed 1000 m (max 350 m at 9600 Bd).
  • Is it possible to connect Wireless M-Bus meters to HWg-PWR?
    Not directly. The HWg-PWR smart gateway supports wired M-Bus only. However, we have successfully tested a wireless-to-wired M-Bus converter.
     
  • Where can I find the prices of your devices?
    Ask our distributors, or request a quote directly from us using the form at this page.
  • What is the warranty?
    The standard warranty is 2 years, can be extended upon request.
