The invention relates to a modular control system for fluidic control devices, comprising a display and/or operating unit (20) with an inductive interface. The display and/or operating unit can be detachably connected to a fluidic control unit (50) in a relative position, in such a way unit that the inductive interface is coupled to a corresponding interface of the control device. Encoded signals (4) can be transmitted via the inductive interfaces, said signals containing both information and energy transmitted from the control unit to the display and/or operating unit in order to operate the same.
