Use the Schedule feature to configure time and day periods for recording trend data for object trend extensions. In the schedule, add the trend extension to the Scheduled Items list and select the desired trend extension attribute. Make sure the trend extension is the Key Item in the Scheduled Items list. Then use the weekly schedule to define the days and times you want to record trend data for the selected object trend extension.

For more information on trend extensions and trending, see the examples below and click one of the following:

For instructions on how to schedule a trend extension, see Scheduling a Trend Extension.

Example 1:

To collect trend samples starting at 6:00 A.M. Monday through Friday and at 8:00 A.M. on Saturday and Sunday, and stopping trend collection at 8:00 P.M. on all days, configure a schedule as follows:

In the Scheduled Items list, add the desired object trend extension and select the trend extension’s Enabled attribute as the Scheduled Attribute. Make sure the trend extension is the key item.

On the Weekly Schedule tab, set the Default Schedule Command to False and configure the event to begin and end according to the following table:

Table 1. Example 1 - Event Configuration

6:00 A.M. - 8:00 P.M. (06:00 - 20:00)

Example 2:

You may want to define how many trend samples are collected during specific periods of time. You can use a shorter trend sampling interval to collect more trend samples during the day when there is more activity in the building, and use a longer trend sampling interval to collect fewer trend samples at night when there is less activity in the building.

To take samples every 60 seconds from 6:00 A.M. to 6:00 P.M. Monday through Friday, every 600 seconds from 6:01 P.M. to 5:59 A.M. Monday through Friday, and every 600 seconds from 12:00 Midnight to 11:59 P.M. on Saturday and Sunday, configure a schedule as follows:

In the Scheduled Items list, add the desired object trend extension and select the trend extension’s Sample Interval attribute as the Scheduled Attribute. Make sure the trend extension is the key item.

On the Weekly Schedule tab, set the Default Schedule Command to 600 seconds and configure the event to start and end according to the following table:
