Creating Transactions
Introducing Transactions
FactoryTalk Transaction Manager transactions move data between the
control system and the enterprise system. Binding is the process of mapping:
 A column in a database table to a data point in a control system,
expression, or a literal string.
 A parameter in a stored procedure to a data point, expression, a literal
string, or a null value.
A configuration can contain any number of transactions, each running
independently based on a trigger event. Although the number of transactions
in a configuration is unlimited, you cannot exceed the tag count for which
you are licensed (see Activation Options (page 33)). In a configuration that
uses online edits, you can edit existing or create new transactions while the
configuration is running. For more information, see chapter Understanding
Online Edits (page 111).
You can assign the following attributes to a transaction on the Transaction
Definition dialog box (click Step 5 on the Configuration Checklist):
 Transaction name.
 Transaction time out.
 Data object name.
 Bindings of data object elements to data points/expressions.
 Trigger event.
