Troubleshooting: Trend data is not scrolling

On the runtime trend display, if the

VCR

buttons are visible, make sure the

Pause/Resume

scrolling button (in the center) is not paused (in a down position). If it is, click the button to resume scrolling, or right-click the trend and then select

Scroll

.

On the

Display

tab, make sure the

Allow Scrolling

check box is selected.

On the

General

tab, select

Chart Update Mode

. The refresh rate may be set too high, or the

On change heartbeat or deadband

options may be set too low, causing a long delay between updates.
