The invention relates to a method for controlling and monitoring a functional unit (2) having a display apparatus (3) for displaying state patterns and functional elements (4), a state pattern describing the switching state/the switching states of the at least one functional element (4), which method comprises: a) transmitting a control signal from a control apparatus (5) to the functional unit (2), the control signal comprising information content regarding a state pattern to be displayed by means of the display apparatus (3); b) displaying a state pattern by means of the display apparatus (3) using the control signal, c) generating a readback signal, the readback signal comprising information content regarding the displayed state pattern, d) transmitting the readback signal to the control apparatus (5); e) comparing the information content of the readback signal to the information content of the control signal. The method is characterized in that the information content regarding the state pattern to be displayed is transmitted in the form of DC signals on one or more control lines (8a) from the control unit (5) to the functional unit (2) and the readback signal is transmitted back in the form of an AC signal from the functional unit (2) to the control apparatus (5).
