Operating method for bus controlled valves

摘要

The method operates one or several groups of valves through a bus. An external bus section is supplied by a central routing station for one or more electronic building blocks. Not only the information about the choice of which valve group is to be controlled but also the signal delineating the particular valve involved is superimposed onto the external bus. There is one electronic unit (1) per bus which is fed with the control signal of the central routing station and outputs to the individual valves of a group. Between the valves is a flexible internal bus cable.
