M-Bus – the energy Bus

Bachmann electronic enables simple configuration with the MBUS201 adapter

Power stations use a large number of energy meters for measuring gas, heat, water and electricity. Appropriate additional devices such as routers are normally used to connect these devices to the automation system via standard fieldbuses. However, these intermediate devices make maintenance and configuration tasks more difficult. The MBUS201 adapter from Bachmann now simplifies this issue.

The M-Bus specified in the EN61334-4-1 standard enjoys widespread use for the connection of energy meters. The MBUS201 adapter makes it easy to connect to the M-Bus communication network. Each M-Bus station is configured as a virtual card in the Bachmann SolutionCenter. In this way, the status of the meters can be queried effortlessly. It also simplifies fault detection, the initiation of restarts or the reading of data from the connected units.

Provided with a robust metal housing, the MBUS201 adapter is fitted directly onto a COM port of the Bachmann M1 controller. Up to five energy meters can be connected to the adapter. The serial interface is galvanically isolated in order to ensure maximum safety and availability. An LED integrated in the MBUS201 indicates the bus status and that of its power supply.
