View timestamp and quality information for an I/O tag

The InTouch HMI places value, time, and quality (VTQ) indicators on all data values delivered to VTQ-aware clients. InTouch uses a set of dotfields as indicators of data quality that are useful for troubleshooting purposes.

• The .Value dotfield contains the value of the specified tag. This is also the default dotfield of every InTouch tag. If no other dotfield is specified, the .Value dotfield is assumed.

• The set of Time dotfields are time stamps indicating the last time a tag was updated.

• The Quality dotfields show the reliability of data values assigned to an I/O tag.
