## Time-lapse You can replay up to 24 hours of Graphics, Alarms, or Trends pages starting on a specified date and time. Time-lapse can be a helpful troubleshooting tool. The Graphics page can replay only trended values. Values that are not trended are grayed out. Floorplan areas without trend data are dark grey. NOTES If a graphic is linked to a microblock value without an embedded trend but a Digital Trend or Analog Trend microblock is attached to the linked microblock by a wire, Time-lapse will use the wire trend's value. Data in a data table, chart, or color map does not change when the graphic is viewed in Time-lapse. For Time-lapse to show thermographic colors, the WebCTRL® application polls each router in the system at specified intervals and collects color. Color is collected for the router and its downstream controllers only if their control program contains a Setpoint, Set Color, or Set Color If True microblock. The Server then uses the collected colors to create a trend called Color Trend.

### To play Time-lapse Select the location on the tree where you want to see the time-lapse. Click at the top of the page. In the Replay field, select the length of time that you want to replay. The replay will step through the data at the interval shown. In the Start field, select the date and time that you want the replay to begin. You can click: The buttons to change the day or time. The to select the date. A date/time field, and then type the new number. Click Accept. The time-lapse immediately begins to play. Use the following items to work with the time-lapse. TIP You can enable historical trending for trended values to have more trend data available in Time-lapse and to have the data retrieved faster. NOTES While in time-lapse, you can navigate to other locations in the tree. You can select an alarm on the Alarms page and then click the Activate Time-lapse button. This changes the time-lapse to the 1-hour period in which the alarm occurred. You can step backward or forward through the time-lapse at 1-minute intervals to see what other alarms occurred during that hour. You can also go to Graphics or Trends to see what else happened when the alarm occurred. The white horizontal line on a Trends time-lapse indicates where the replay currently is in the time-lapse range.
### To change polling interval or duration or to turn off color collection On the System Configuration tree, select System Settings. On the General tab under Trends, do one of the following: In the Poll Interval field, change the frequency that the server collects color trend data from the routers. NOTE Last Poll Duration shows how long the last polling of the routers took. If directed by Automated Logic® Technical Support, uncheck Enable Server Trending of Color to stop color collection.
