Data Context

Use

Data Context

to view all invocations of an Add-On Instruction (AOI) across a project. Data Context provides a list of where each AOI is used, including its fully qualified name and the structure of any AOIs containing it, if it is nested within other AOIs.

To open

Data Context

:

In the program ladder diagram, right-click the Add-On Instruction invocation, then select either
Open instruction parameters
or
Open instruction logic
.
In the
Add-On Instruction Instance Tab
or
Add-On Instruction Routine Editor
, select the drop-down list in the upper right that shows the name of the AOI invocation.
