Abstract
The invention concerns a method and an apparatus for time-staggered generation of identifying signals by programmable automation components (AK1, AK2) with a system time recorder (SZ). A user (A) or an automation component (AK1, AK2) or a user program (AP) can register a time-staggered identifying signal (K) with an event manager (EV). The event manager (EV) controls a system time counter (SZ) and signals waiting events (E1-E3) back to the user (A) or the automation component (AK1, AK2) or the user program (AP). The event (E1-E3) is thereby enabled and an identifying signal (K) is generated.
Claims11
A method for time-staggered generation of identifying signals by programmable automation components having a system time recorder, comprising assigning an identifying signal to a temporal event, registering the event with an event manager with a required event time-delay, chronologically sorting the events by the event manager utilizing a system time recorder having a time interval lasting until a next event is started by the event manager, wherein the system time recorder signals when the time interval has elapsed, the event is enabled, and an identifying signal is generated.
An apparatus for time-staggered generation of identifying signals by programmable automation components having a system time recorder, comprising a device for assigning an identifying signal to a temporal event, an event manager for registering the event with a required event time-delay, wherein the event manager chronologically sorts the events, further comprising a system time recorder having a time interval lasting until the next event can be started by the event manager, and wherein the system time recorder signals when this time interval has elapsed, and the event having been performed, and an identifying signal is generated.
