Abstract: An industrial plant and method for graphically representing synchronous relationships, wherein the industrial plant includes a first control device in which a first user program executes, a second control device in which a second user program executes, and a plurality of drives which are controlled and/or regulated by the user programs, where objects are assigned to the drives in the user programs, synchronous relationships exist between the objects, the user programs have a plurality of different flow structures which have an influence on the synchronous relationships between the objects such that a synchronous relationship is either an active synchronous relationship or an inactive synchronous relationships, and where an apparatus for graphical representation of synchronous relationships is provided between the objects to simplify diagnosis of synchronous operations.

Abstract: A method for diagnosing a user program for controlling movement and positioning tasks of drives operated to execute a movement path of an apparatus, wherein the apparatus and movement path are depicted as a three-dimensional view in a first output element, to depict the movement path, a graphic element formed as a polygonal chain is generated for movement sections, which is operated in a force sensitive manner so that a user can select a location on the polygonal chain with a pointer device and obtain a display of an output field with a line of code that has the program instruction that is responsible through the execution for reaching the location within the movement section of the apparatus or position vector, and a recording method was performed in which the current position vector and the associated line of code or a code line index are recorded at sampling time points.
