Desigo™ PX Open

PX M-bus

The PX M-bus integration solution provides a platform for the integration of

M-bus meters, and permits the exchange of information with the Desigo building

automation and control system.

With the generic approach to the read-out of M-bus data points as implemented

in the product, a wide range of third-party products can be integrated.

Function

The M-bus data points are integrated via the communication between the PX M-bus

automation station and the meters. The data can be displayed and set centrally via the

building automation and control system.

• Measurement of consumption data and remote monitoring of max. 250 consumption

and heat meters at the automation level.

• Mapping of M-bus data, such as cumulative energy (kWh), cumulative volume (m

flow (m

/h), power (kW), flow temperature (°C), return temperature (°C) etc. to

BACnet.
