Change Value

The Change Value pushbutton at the bottom of Data Log Trend allows you to Change the Value of a Tag from the Trend Display.

1.      Click a Tagname from the Trend

2.      Click Change Value

3.      The Change Value Dialog Box Opens.

If the user does not have the Area and Level Security required by the tag, a Login Dialog Box opens.

Hint -      Normally, you cannot change the value of a "Read Only" tag.  Most measurements are Read Only. Even if you can change the value, the next scan will reset it to the value read from the field IO.
