Field{T}

A Field class is provided in the .NET Script operation to handle qualities and timestamps. Note that the Field class is a generic class and a type needs to be specified for its Value property.

It enables the manipulation of qualities and timestamps. Output fields are of integer, DateTime, string and double types, and only a null value in the table will indicate a bad quality data point.

The field type can be used when declaring global variables (under the variables tab) to logically group quality, timestamp and value information in a single class.

Class properties

DateTime Timestamp	The timestamp of the field.
