2.1.1.2 Description
The MP-Bus master module 750-643 is used for the digital control of
actuators for dampers and control valves, as well as VAV volume flow
controllers and FLS window ventilation systems via the MP-Bus.
The MP-Bus (Multi Point Bus from the Swiss company Belimo) is a master-
slave bus, which is mainly used for ventilation systems in the heating and
ventilation area.
The I/O module 750-643 module acts as a MP-Bus Master that is integrated
into a fieldbus communications controller for local control. The fieldbus
network controller communicates from a network, such as Ethernet or
LonWords to bridge data to the MP-Bus Master module.
