FactoryTalk Transaction Manager Sample

Applications

External Trigger Sample Application

The External Trigger sample application illustrates how an external

application can trigger a FactoryTalk Transaction Manager transaction. Use

external triggering to create a custom user interface to the FactoryTalk

Transaction Manager application or to integrate FactoryTalk Transaction

Manager functionality into an existing software system.

The Extras directory on the FactoryTalk Transaction Manager product CD

contains the External Trigger sample application discussed in this appendix.

Contents

The example application contains the following elements:

 A Microsoft Excel spreadsheet named ExternalTriggerSample.xls. The

integer number in cell A1 is the data point that is sent to the database.

 A Microsoft SQL database with a table named ExternalTriggerSample

that contains three columns: ExternalTriggerDatabaseID (an

Autonumber field), ExcelValue, and a timestamp.

 A FactoryTalk Transaction Manager configuration that contains a

single unidirectional transaction named ExternalTriggerTransaction.

This transaction obtains a data value from cell A1 in an Excel

spreadsheet and appends a record named ExternalTriggerSample in the

Microsoft SQL database. The transaction is defined so that it can be

triggered by an external application.
