Object ExtTrend

An extension of the PmVar variable of the PmaData object for connecting to the PmaTrendGroup object. Format of saving the data extension as string:

The contents of complete data extension (all configurators) can be saved as a single string. See Format of saving the data extension as string.

Id={Trend;sPmaObject;fOrder;sName;fMin;fMax;sUnit;sColor;sDisplayName;fSensitivity;sParams;nValueType;nBit}

This data extension registers itself automatically into the PmaTrendGroup object after starting the application. Therefore it is forbidden to create the requested item on the "PmaTrendGroup > Data" page! The corresponding variable for trend may be created directly in the PmaTrendGroup object as a PmVar object, or it can be registered as a data extension (ExtTrend).

If all items for the PmaTrendGroup object are of the "Data extension" type, then the "PmaTrendGroup > Data" page may remain empty. If there are both types of items present in the PmaTrendGroup object, then in the database table the PmVar type items will be entered first followed by the "Data extension" items.
