Abstract

See full text

An improved system for handling events in an industrial control system is disclosed. A module in an industrial controller is configured to generate an event responsive to a predefined signal or combination of signals occurring. The event is transferred to an event queue for subsequent execution. The event queue may also be configured to store a copy of the state of the module at the time the event is generated. The event queue may hold multiple events and each event is configured to trigger at least one event task. Subsequent events that occur during execution of the event task are stored in the event queue for later execution. An event, or combination of events, may trigger execution of an event task within the module, within the controller to which the module is connected, or within multiple controllers.
