  • Smart Meter Interface for M-Bus

    The AmsMBUS module is a client interface module in the Amplex Module System. It is designed for wired two-way communication with M-Bus compatible utility meters from various manufacturers.

    The AmsMBUS module can easily be connected with up to ten utility meters. The AmsMBUS module collects readings and other data from the meters and subsequently transfers these data to an AmsCPU/AmsCPU-IO module that acts as a data concentrator and WAN module. The AmsCPU/AmsCPU-IO module delivers the data to the central server when required. Direct communication and power supply between the AmsMBUS module and the AmsCPU/AmsCPU-IO module are handled by an incorporated A-Bus interface, which is based on the industrially proven RS-485 technology.

    • A-Bus two-way communication with A-Bus masters, e.g. AmsCPU, AmsCPU-IO
    • Mini master, EN 13757-2 standard. Only primary addressing is used. A unique primary address within the range of 1 – 250 must therefore be assigned to every meter.
    • The module is automatically discovered by the AmsCPU module. In case a module is disconnected from the AmsCPU module, this is reported to the server application and the module is listed as missing. If the module is reconnected to the AmsCPU module or another AmsCPU module, it will be rediscovered by the system.
    • The real-time clock is automatically synchronized with the AmsCPU module which in turn is synchronized with the Network Time Protocol (NTP).
    • AMS Status LED (green): indicates whether the A-Bus is up and running.
    • The software on the AmsMBUS module can be updated remotely from the central server.
    • New software is transferred without interrupting the normal functionality of the AmsMBUS module. When the software has been transferred, the integrity of the software is checked and the software is installed.
    • A built-in self-test (BIST) is performed after power-up.
    • Watchdog and brown-out reset ensure that the system is up and running at all times.

    • A-Bus client module
    • M-Bus+ and M-Bus- connect to one meter or a collection of meters. The AmsMBUS module can be connected to a maximum of 10 meters. The meters are polarization independent.
      Data transfer rate 300 or 2400 bps
