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.
