Allows users to import the most recent data by specifying a duration

Create Index

If enabled, the source will create a new unique index for every row of data read from the source. The index will be incremented on every execute. The starting value is determined by the Index Start Value property.

Index Starting value

The starting value for the index if the Create Index property is enabled.

Index Field

If the Create Index property is disabled, select a field from the data source to use as the index field. Indexes do not have to be unique.

Select TAB

Select the fields you wish to import from the specified data set and set the data types.

NOTE: Proficy Historian has a default limit of returning 5000 fields, so you will need to apply a filter or import a subset if the fields you are specifically requesting are not shown in the returned fields.

Five data types are supported and interpreted as either Discrete or Continuous when read:

String (S) - Discrete
Double (D) - Continuous
Integer (I) - Continuous or Discrete (Conversion allowed)
Timestamp (T) - Timestamp or Discrete (Conversion allowed)
Quality (Q) - Discrete or Continuous (Conversion allowed)

Convert between these data types by selecting the required fields from the list and clicking on the conversion buttons provided. Only valid conversions are supported.

Click Refresh to refresh the field list if property changes have been made.

Preview TAB

Provides a sample preview of the data set as read using the currently specified properties.
