Configuring Timers › Add Timers › How Catchup Works

How Catchup Works

When you define a timer, you specify whether catchup is required if a region running the timer is unavailable when the timer is due to be activated.

Note that if you enter YES in the Catchup Required? field on the Timer Schedule panel, catchup applies to all schedule items entered for this timer.

• If you specify YES, then the scheduled action or actions are performed when the region becomes available, provided that the time specified in the Window field has not elapsed, with the exception of the situation noted below.
• If you specify NO, no belated processing occurs for that timer.

Note: In the case of timers that define actions that are repeated, catchup can be requested. If the specified end time has passed by the time the region running the timer becomes available, the specified action or actions are still performed once. If the region running the timer becomes available part way through the specified time period, the specified action or actions continue at the specified intervals until the specified end time.

Catchup Window

If you specify that catchup is required, you can identify the window in which catchup is performed. You can specify a value between one minute and 24 hours. If the region running the timer becomes available before the catchup window ends, catchup is performed.
