4 MP-Bus
MP-bus = multi-point bus
The MP-Bus (Multi-Point) is a simple sensor/actuator bus, which is used for certain technical systems of the
building automation system. The MP-Bus serves to control HVAC actuators for dampers, control valves and
volume flow controllers from the Belimo product range. Up to eight different devices from HVAC systems can
be connected to an MP-Bus master using 3-wire technology. Additionally, a sensor can be connected to
each of these eight devices; the sensor is addressed by the MP-Bus. An additional range of products with an
MP-Bus connection is the FLS window ventilation system by Belimo (see Belimo documentation for the
connection of the Belimo actuators).
The MP-Bus was developed by Belimo for connecting valves, throttle valves, air valves, fire dampers, and for
window ventilation systems.
4.1 Topology
There are no restrictions whatsoever with regard to the topological structure of MP-Bus strands: star, ring,
tree or mixed topologies are possible. The length of the entire bus strand depends on the selected cable
cross-section and the type as well as the number of connected drives! Documentation from the Belimo
Automation AG contains further information.
