Method and system for executing an event-oriented control program

A method of executing an event-oriented control program on a programmable logic controller of an automation system,

• wherein the control program comprises a plurality of functional modules,
• wherein an execution of the individual functional modules is triggered in an event-controlled manner on the occurrence of activation events that are each associated with the individual functional modules,
• wherein priorities are assigned to each of the activation events,
• wherein the method comprises:
• detecting activation events that have occurred;
• and
• executing, in an execution sequence defined on the basis of the priorities of the individual activation events, the functional modules that are each associated with the activation events that have occurred.

An execution environment for executing an event-oriented control program on a programmable logic controller of an automation system,

• wherein the control program comprises a plurality of functional modules,
• wherein the execution environment is configured to trigger an execution of the individual functional modules in an event-controlled manner on the occurrence of activation events that are each associated with the individual functional modules,
• wherein priorities are assigned to each of the activation events,
• wherein the execution environment is configured to detect activation events that have occurred and
• to execute in an execution sequence defined on the basis of the priorities of the individual activation events the functional modules associated with the activation events that have occurred.
