Modular control system having wireless connection of the modules

摘要

The device has a master module (3) in a separate housing (4) and at least one slave module (2) in a separate housing adjacent to the master module with inputs and/or outputs for connecting to sensors and/or actuators. The modules exchange data and/or control commands via a data bus (13) and suitable interfaces (15,16) . The interfaces of the master and slave modules are arranged at approximately the same level and at a small distance apart and are connected together wirelessly.
