Page 21: Information On The Mp Bus
Information on the MP bus Information on the MP bus The MP bus is a Belimo master/slave bus system. It enables simple wiring of up to eight volume flow controllers (slaves) which can be parameterised and read out centrally (e.g., switch cabinet) via an MP master. This makes it easy to check the function of up to eight volume flow controllers. -
