Timed
Events
Timed events are triggered after a certain amount of time has passed. Timed events can be
repeated, set N = 0 for continuos.
Event Priority Events have priority. Sequences launched by events inherit the priority from that Event. A
higher priority event can stop a lower priority sequence, but a lower priority event cannot stop a
higher priority sequence.
User Events (i.e. sequences triggered by user) are also treated as events having a priority of
50. For example, Events 1 and 2 could have a higher priority than the user, thereby allowing
them to interrupt a user initiated sequence, while Event 3 with a lower priority than the user,
cannot interrupt a user initiated sequence.
An event can start in an enabled or disabled state. A disabled event is ignored. Events can
enable or disable other events. The enabling or disabling function works independent of the
sequences, so lower priority events can enable or disable events, even when there is a higher
priority sequence running.
In the example shown Figure 6-22 on page 99, The pulse channel is being monitored for a
positive threshold crossing from below 0.67804 to 0.900062. The event is enabled, with a
priority of 50 and set to fire the sequence "Start Pump." This event will also enable “event3” and
“event4”, while disabling “event2.”
