schedule-TriggerSchedule
TriggerSchedules are special-purpose schedules, providing scheduling control for either linked actions or topics of other
components. TriggerSchedule fires actions or topics, there is no continuous output. TriggerSchedule is available in the schedule palette.
By default, for any TriggerSchedule copied from the schedule palette, the main Trigger output slot is pinned on the component’s glyph (shape on the wire sheet), as well as the following additional slots:
| Property | Value | Description |
|---|---|---|
| Enabled | true (default) or false |
Enables/disables firing of trigger outputs. |
| Next Trigger | (defaults to null) | Reports next scheduled trigger firing time. |
| Last Trigger | read-only | Reports the timestamp of last configuration change. |
| Next Trigger Search Limit | 2160h 00m 00s (default)
|
Limits how far into the future to search for the next trigger. This setting prevents an infinite search due to a poorly configured
schedule. Default is 90 days (2160 hours). Format is:hhhh mm ss |
| Next Value | read-only | Reports the next scheduled output value, at Next Time. Value is meaningless if Next Time is null.
|
| Last Modified | read-only | Reports the timestamp of last configuration change. |
Trigger Missed slot
In addition to the main Trigger output slot, the TriggerSchedule has a Trigger Missed slot, also a topic type slot. If the station was not running when a scheduled trigger was to occur (appeared previously in
the Next Trigger property), upon station startup the Trigger Missed slot fires once.
NOTE:
Trigger Missed always fires only once, no matter many triggers may have been missed.
