The present disclosure relates to a control module circuit having a circuit communication input port, a circuit communication output port, a first controllable unit that has a first controller module, and a second controllable unit having a second controller module. The first controller module has a first communication input port connected with the circuit communication input port and a first communication output port. The second controller module has a second communication input port connected with the first communication output port and a second communication output port connected with the circuit communication output port. The first and second controllable units are adapted to be identified with a permanent identity by way of a transmittable data signal receivable at the communication input port and sequentially received by the first and second controllable units.
