A method for connecting an expansion module to a programmable electric switching device includes initiating a recognition mode within the switching device during which an interrogation is carried out as to whether or not the connected expansion module is initializable. If the expansion module is not initializable, no data is exchanged between the switching device and the expansion module. If the expansion module is initializable, the switching device switches into an expansion communication mode in which data exchange takes place under the control of the operating system of the expansion module.

Method for connecting an expansion module to a programmable electric switching device

A modular electrical device combination includes an operator control module and a computer module that can be electrically coupled to the operator control module. The operator control module has a fastening portion on its rear side for installation into a mounting panel. Mechanical connecting means are provided in an extension at a free end of the fastening portion.

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.

Operator buttons as active buttons

A programmable controller having a processing unit, a screen, a control panel, and signal inputs and outputs, all of which are accommodated in a common housing. Switching functions can be programmed by the user via a menu-driven user interface on the screen. The status display is capable of being switched between an active and an inactive display status of the screen.
