Understand the event data attribute

The event data object attribute is on the Event Data section of the Sample tab.

Event DateTime

Specifies the date and time when the sample is pulled or finalized.

You can do either of the following:

• Map the attribute to an I/O tag to read the value from it.

• Select the AutoGenerate check box to automatically generate a date and time value in the object.

If the attribute is not mapped to an I/O tag and the AutoGenerate check box is not selected, the attribute is not updated. The value is then updated by the MES database.
