Description

[0016] The invention will also be explained in the following with respect to further advantages and features with reference to the enclosed drawing and to embodiments. The Figures of the drawing show in:

[0017] FIG. 1 a schematic representation of a control in accordance with the invention in an automation plant; and

[0018] FIG. 2 a schematic perspective detailed representation of an embodiment of the control in accordance with the invention.

[0019] FIG. 1 schematically shows an automation plant that is built up of a control S in accordance with the invention and of two machines controlled by the control S. The control S controls the machines shown by way of example as a robot arm R and as a punch St.

[0020] The control S comprises at least one control module SM to which at least one signal generator, not shown, can be connected so that the control module SM receives received signals from the signal generator. The input signals are processed by the control module SM into corresponding output signals by which the control S safely controls the machines R and St. The control module SM communicates the output signals to the machines R and St for this purpose.

[0021] The control S can be expanded by at least one additional expansion module E so that the total plant can be expanded in a very simple manner. The additional expansion modules E are connected to the control S in accordance with the invention by means of a bus line for this purpose.

[0022] The control module SM has a display D on which information of the control S can be displayed. The information can, for example, reproduce the configuration information of the control module SM via the signal generator and the machines R and St and in particular which input and output connectors of the control module SM the signal generator and the machines R and St are connected to. The connectors, the connected signal generators or machines and connection options of the automation plant are, above all displayed by the control S on a configuration of the control S.

[0023] For this purpose, the display D of the control module SM is movably supported in accordance with the invention such that a moving of the display D with respect to the control module SM corresponds to an input to the control S. In other words, the display D of the control S in accordance with the invention has a functionality corresponding to a cursor key or accept key so that a user can intuitively carry out the association of the information displayed and thus the configuration on the configuration of the control S using the display D.

[0024] The display D is supported in a spring-loaded manner and is held in a starting position with respect to a housing G of the control module SM. The display D can be moved out of this starting position of the display D, with the moving of the display D comprising a pressing of the display D with respect to the control module SM and the display automatically returning into the starting position with respect to the control module SM on a release of the display D. The moving of the display D can in particular comprise a tilting of the display D with respect to the control module SM in which the user presses the sides of the display D so that the display D tilts in this direction.

[0025] The display D is advantageously tiltable and pressable in nine directions with respect to the control module SM, with an electric contact being established in the control module SM on each tilting or pressing of the display D that provides a corresponding functional signal to the control module SM or to the control S.

[0026] In other words, different input options for the user are shown on the display D such as an association of an input connector 1a of the control module SM to an output connector 2a of the same. The display on the display D digitally reproduces the arrangement of the physical connectors 1 and 2 of the control module SM or of the expansion module E. The user can provide a selection confirmation of the input option to the control module as a functional signal by moving the display D in the direction of the respective input option by means of tilting or pressing the display D so that the input of the user, in this case the association of the one digitally presented input connector 1a with the one digitally presented output connector 2a, is stored in the control module SM.

[0027] In the embodiment shown in FIG. 1, the control module SM has six input connectors 1 and six output connectors 2 that are assigned differently. The assigned connectors 1 and 2 are shown as black boxes and the non-assigned connectors 1 and 2 are shown as white boxes. These physical input and output connectors 1 and 2 are digitally exactly reproduced in the form of represented input and output connectors 1a and 2a on the display D in accordance with the invention so that so-to-say an image of the physical input and output connectors 1 and 2 is visible to the user. The display D here comprises a light emitting diode display or a liquid crystal display.

[0028] On the configuration or association of the connectors 1 and 2 of the control module SM, the user presses the display D in the desired direction so that the information shown in this direction is deemed to be selected and confirmed with respect to the control module SM. The user can in this manner completely intuitively select and input configuration data of the control S by means of the display D without having to operate separate cursor keys in so doing.

[0029] As shown, the expansion module E has a further movably supported display that is in particular of the same type as the display D of the control module SM. The configuration of the expansion module E can hereby be intuitively carried out in the same manner.

[0030] FIG. 2 perspectively shows the control module SM with the display D in accordance with the invention. How movably the display D is supported with respect to the housing D of the control module SM is indicated by the black arrows. The user can in particular press the display D at the corners, at the sides and at the center, whereby the display D is movable in nine directions in total. A different input option can be stored in every direction in this respect.
