Trend tag refers to missing or invalid entry [ERROR 162]

Trend tag TREND refers to missing or invalid entry in history database

Only Conductor NT systems can produce this message.

The tag refers to an entry that does not exist in your history database. The history tag has not been defined, although it is shown. Trend definitions are also affected. Since this history tag has no meaning, there is a problem with any trend group that references it.

Example:

Trendcfg tag CBTE-01 refers to missing or invalid entry in history database.

The Trend error is caused by the fact that there is no Historical tag CBTE-01, which is what the Historical Tag should have been called. The trend group is thus flawed because it is calling up an entry that does not exist.

In the case of the message in the example, it is pretty clear that the Historical Tag named "CBTE01" should be modified to be "CBTE-01" and the Tag Atom entry corrected.

In the example, the Trend error refers, in fact, to an invalid tag, not a missing one. The other form of the error is, of course, to name a trend tag that does not exist at all. To resolve that error, you either eliminate the trend tag entry in the Trend Configuration section, or you correct the spelling of the Trend Tag entry in the Trend group.
