Remote Reading M-Bus Master for M-Bus Meters

The STCM MH2 is an M-Bus network hub, designed to gather data from connected meters and send them, via e-mail, to the user.
Internet connection for the sending of data occurs by using the embedded GSM/GPRS modem or Ethernet interface. The reading values are sent via e-mail, and are available in an attached, “.csv” file – formatted and directly readable in Excel (or an equivalent program). Alternatively, readings can be made locally, using the “STCU Reader” software, provided separately. The device may be remotely configured by SMS or through web server, or locally using the “STXM Reader” software. The STCM MH2, among other functions, can manage the STCR-IO devices, that are M-Bus slave with an input and an output. STCR-IO devices can be configured according to your needs by sending appropriate SMS to the master or through the software “STXM Reader”.
Moreover, there are models available with the datalogger for saving the readings.

  • Meter and/or device reader with M-Bus interface.
  • Reading data sent in “.csv” format, in table form, directly readable in Excel (or equivalent program).
  • Set up of up to two schedulers to automatically send readings daily, weekly or monthly, as well as sending the meter values to configured e-mail recipients.
  • A name may be assigned to each device.
  • Saving all the commands sent and received in a dedicated file in “CSV” format, with the possibility to send the file via E-mail.
  • Automatic update of date and time, with standard time and daylight saving time management.
  • Receiving SMS from telephone operator (credit low, credit check etc…).
  • Ability to select the data transmission mode between Ethernet and GPRS.
  • Remote device configuration by means of sending text messages or through the internal web server, or locally by means of PC and “STXM Reader” software.
  • The user, by sending text messages to the remote system, can:
    1. Verify the status of the control unit (alarms, data).
    2. Request the sending of the current system readings.
    3. Configure the device.
    4. Command available output relays (configurable in on/off or impulsive mode).
  • The remote system, if configured, upon an input status change, sends a warning text message – the text of which may be set up by the user – to the telephone numbers set up.
  • Verifies device alarms (failures or tampering), able to be set up via the scheduler, with reports of possible anomalies via text message to the telephone numbers set up.
