Control System for a Partition System

A control system for a partition wall system that includes individually displaceable partition wall elements that can be disposed to form a closed partition wall, each partition wall element is displaceable in a guiding rail and has a drive motor for displacing the partition wall element, comprising:

• a subordinate control unit for each of the individually displaceable partition wall elements;
• a position data detection unit configured to detect a position of each of the individually displaceable partition wall elements independently from an operating state of the control system at least during interruption of a power supply.

A partition wall system including a control system comprising:

• a subordinate control unit for each of a plurality of individually displaceable partition wall elements;
• a position data detection unit configured to detect a position of each of the plural individually displaceable partition wall elements independently from an operating state of the control system at least during interruption of power supply to it.

A method for operating a partition wall system, including a plurality of individually displaceable partition wall elements and a control system, which has a central control unit and subordinate control units in each of the plural individually displaceable partition wall elements, comprising:

• bidirectionally exchanging position data between each of the subordinate control units, wherein the subordinate control units are equipped with a position data detection unit;
• and
• transmitting by the subordinate control units of the respective position data to the central control unit, via the respective position detection units, in that in an event of failing power supply once the power supply is restored.
