Computer-implemented method for modifying application programs (2, 3) of an industrial plant, comprising the following method steps: a) providing at least one application program (2, 3) on an industrial plant, wherein the at least one application program (2, 3) has multiple program points (P1 to P5); b) providing at least one graphical representation (101 to 103; 200), wherein the at least one graphical representation (101 to 103; 200) is a photograph of the industrial plant, wherein the at least one graphical representation (101 to 103; 200) shows at least one system state of the industrial plant, wherein the system state corresponds to one of the multiple program points (P1 to P5) and each of the graphical representations (101 to 103) is linked with at least one of the multiple program points (P1 to P5) of the at least one application program (2, 3); c) executing the at least one application program (2, 3) and, if the at least one application program stops, executing the following method steps: d1) displaying the at least one graphical representation in order to compare the current system state of the industrial plant with the at least one graphical representation, d2) receiving a user input in order to select a graphical representation or a link between a graphical representation and one of the multiple program points (P1 to P5), and e) finding one of the multiple program points (P1 to P5) with which the selected graphical representation (101 to 103) is linked, using the link between the at least one graphical representation (101 to 103) and the one of the multiple program points (P1 to P5), wherein the finding of the program point (P1 to P5) allows a modification of the at least one application program (2, 3) by virtue of an editor being displayed to a user, wherein the editor preferably comprises a graphical model of the at least one application program (2, 3) and wherein modifications in the at least one application program (2, 3) can be performed by means of the editor, wherein the link of the at least one graphical representation (101 to 103; 200) with the corresponding one of the multiple program points (P1 to P5) is updated automatically, in accordance with the modifications of the application program (2, 3); and f) executing the at least one modified application program in order to control the industrial plant. a) providing at least one application program (2, 3) on an industrial plant, wherein the at least one application program (2, 3) has multiple program points (P1 to P5); b) providing at least one graphical representation (101 to 103; 200), wherein the at least one graphical representation (101 to 103; 200) is a photograph of the industrial plant, wherein the at least one graphical representation (101 to 103; 200) shows at least one system state of the industrial plant, wherein the system state corresponds to one of the multiple program points (P1 to P5) and each of the graphical representations (101 to 103) is linked with at least one of the multiple program points (P1 to P5) of the at least one application program (2, 3); c) executing the at least one application program (2, 3) and, if the at least one application program stops, executing the following method steps: d1) displaying the at least one graphical representation in order to compare the current system state of the industrial plant with the at least one graphical representation, d2) receiving a user input in order to select a graphical representation or a link between a graphical representation and one of the multiple program points (P1 to P5), and d1) displaying the at least one graphical representation in order to compare the current system state of the industrial plant with the at least one graphical representation, d2) receiving a user input in order to select a graphical representation or a link between a graphical representation and one of the multiple program points (P1 to P5), and e) finding one of the multiple program points (P1 to P5) with which the selected graphical representation (101 to 103) is linked, using the link between the at least one graphical representation (101 to 103) and the one of the multiple program points (P1 to P5), wherein the finding of the program point (P1 to P5) allows a modification of the at least one application program (2, 3) by virtue of an editor being displayed to a user, wherein the editor preferably comprises a graphical model of the at least one application program (2, 3) and wherein modifications in the at least one application program (2, 3) can be performed by means of the editor, wherein the link of the at least one graphical representation (101 to 103; 200) with the corresponding one of the multiple program points (P1 to P5) is updated automatically, in accordance with the modifications of the application program (2, 3); and f) executing the at least one modified application program in order to control the industrial plant.
