Programmable controller with control button as active button is highly reliable, convenient to operate and enables its switching program to be checked for correct operation without outside aids
The programmable controller has a computer unit, a visual display screen (6), a control unit (4,5), signal inputs (2) and signal outputs (3). The computer unit, signal inputs and outputs are mounted in a common housing (1) and switching functions can be programmed by the user via a menu-guided user interface on the screen using predefined functions. A control unit button can be switched to be an active button by a programmable function, whereby the progress of a switching function depends on its operation. The active key can be used to simulate a signal input.
