Question

The Trend History does not work after adding or removing tags in the Trend worksheet.

Answer

When a tag is inserted or removed FROM a Trend worksheet, the format of the history files (*.HST) is modified.
The same HST file cannot have two different formats, otherwise the data will not be retrieved from it properly by
the Trend object. If you need to add or remove tags for history files, there are two valid procedures: Create a new
Trend Worksheet or delete the old *.HST files.
