MBUS201 Master

Energy meters (gas, heat, output, water, etc.) are required in power plants, and in combined heat and power generation in particular, for regulation, as well as accounting. The M-Bus standardized in EN 61334-4-1 is highly prevalent in Europe for the connection of these meters. The OSI model, if M-Bus is the physical layer, the data link according to IEC 870 and the application layer according to EN 1434-3 are specified for this protocol. An integrated solution is provided by a rugged and easily installable M-Bus adapter and its convenient integration as a fieldbus in software communication.

The MBUS201 Master enables easy connection of a serial RS-232 interface on M-Bus via an adapter. The M-Bus is a widely used fieldbus in accordance with EN 13757 for reading out consumption data from meters (electricity, water, gas, heat). Transmission occurs serially via voltage and current modulation two-wire line that is protected against polarity reversal. The M-Bus protocol is integrated as an intuitively configurable fieldbus, and is addressed via the UFB (Unified FieldBus ) software interface.
