A method for modifying a program of an industrial automation component, wherein the program includes a plurality of program elements, where the program is structured in units, a unit includes a group of program elements and can include both published program elements having an interface that can be referenced by the program elements of other units and unpublished program elements, and where a checksum is calculated and is assigned to the unit using the interfaces, such that if at least one program element of the version of the unit stored in the engineering system is modified, then the modified checksum is compared with the previous checksum version present in the automation component, and only the modified unit is transferred if the checksums match such that consistency of the program is maintained and the software updateable more quickly.

Method and engineering system for modifying a program of an industrial automation component

The invention relates to a method for graphical presentation of objects and/or technical processes on a screen as well as to a system for implementing the method. In some cases different views may be frequently selected, and these views may be presented in different display windows. To edit the totality of views or subsequently look at them, a frequent change of view may be required. Such changes of view may be cumbersome and tedious and take time. To resolve this problem, the display area () is equipped with a least one element, () which can be activated by an input device (). Activating the element () expands or contracts the contents of the display area () by a graphical object (). In this way a frequent change of view is avoided, which provides ergonomic benefits to a user working with the graphics.

Method for graphical presentation of objects and technical processes on a screen and computer program product used for this purpose

A method is provided for graphical presentation of objects and/or technical processes on a screen, as well as an editor implementing the method being provided. A tooltip appears when a pointing device such as a computer mouse for example uses its mouse pointer to remain for a predetermined time over a predetermined section of the display area, and that the tooltip graphically presents at least a part of the object and/or of the process in a modified way compared to that shown in the display area. In this way, with the aid of the tooltip, the same object and/or the same technical process can be presented in a number of views.
