Abstract
A programmable controller has a processing unit, a display screen, an operator unit, and signal inputs and signal outputs. The processing unit, the display screen, the operator unit, the signal inputs, and signal outputs are accommodated in a common housing, and switching functions can be programmed by the user on the basis of predetermined functions by using a menu-assisted user interface on the display screen. A button of the operator unit can be switched to an active button through the use of a programmable function, such that the sequence of a switching function depends on operation of this button.
