SQL Logger Tags

The SQL Logger tag type allows you to select where data to be logged is to come from.  Before using an SQL Logger tag you should create a SQL Logger Group tag as described in the preceding section. SQL Logger tags contribute values to SQL Logger Group tags.

Each record added to the database will include:

•    An index value indicating which tag's value is being recorded

•    A time stamp

•    The value of the tag being logged at that moment

•    A flag to indicate whether the value is 'manual data'

•    A flag to indicate whether the value is 'questionable data'

•    An alarm flag
