SIU-MBMs are gateways that transform data from the M-Bus and wireless M-Bus protocol into the Modbus TCP/IP protocol, to then send them to a master.

Two versions are available: SIU-MBM-01 and SIUMBM-02. Both can integrate up to 20 wired M-Bus devices, while SIU-MBM-02 is also able to manage up to 32 wireless M-Bus devices simultaneously.

Moreover, thanks to the SIU-MBC radio transmitter, SIU-MBM-02 can read consumption of devices with pulse output such as gas or water meters.

The UCS software, available for free download, scans and identifies the M-Bus devices connected to SIU-MBM and the wireless M-Bus devices operating withing the range, automatically generating the Modbus map.

For rapid and automatic integration with the VMU-C EM master, UCS generates a Modbus driver that can be imported directly.

Benefits

• Simple integration. SIU-MBMs integrate all devices that communicate with the standard M-Bus protocol, wired and wireless. Thanks to the SIU-MBC radio transmitter, they can also read data of devices with pulse outputs.

• Product sold and usable individually. The products SIU-MBM, SIU-MBC and the master VMU-C EM have been created to be integrated in the same system, where necessary, and designed to operate efficiently together. However, they may be sold and used individually as well.

• Ease of installation. SIU-MBMs can be installed on DIN rail. SIU-MBC can be installed on DIN rail or wallmounted by means of screws or tube/mast mounted by means of zip ties and it is suitable also for outdoor installation.

• Tamper-proof. Subsequent modifications to the configuration of SIU-MBC are blocked by means of the anti-fraud system.

• Free specific software. The UCS software enables rapid configuration with a simple and intuitive interface. The software and subsequent updates are free.

• Auomatic scanning and mapping. The UCS software automatically scans and maps the M-Bus devices present in the system.

• Automatic import of mapping into VMU-C EM. The UCS software is able to generate the driver to easily import the map of Modbus registers of all the integrated devices in the VMU-C EM master.
