Parameter in
Imported File
Connection in
Imported File
Operation Value Final Connection box What happened in this case
\Prog1.InA \Prog2.OutA Connect \Prog2.OutA This connection exists in both the import content and in the program in the
project, so the connection is the same.
\Prog1.InB \Prog2.OutB Connect \Prog2.OutB The endpoint parameter does not exist in the target project file.
If you are importing the program offline, the error flag appears. You can
continue the import, but you must resolve the error before you can download
the project to the controller.
If you are importing the program online, the red-x error appears, and you
must resolve the error before continuing the import.
To resolve the error, you can either:
• Set the Operation Value to Disconnect (see Example Row 3 in this table).
• Select an existing parameter in the Final Connection box to reassign the
connection (see Example Row 4 in this table).
\Prog1.InB \Prog2.OutB Disconnect \Prog2.OutB Example Row 3: Parameter \Prog2.OutB does not exist in the target project, so
you set the Operation Value to Disconnect.
\Prog1.InA \Prog2.OutA Connect \Prog3.OutB Example Row 4: Parameter \Prog2.OutA does not exist in the target project, so
in the Final Connection box select an existing parameter to reassign the
connection.
\Prog1.InC none Connect \Prog3.OutD This connection did not exist, so in the Final Connection box select an existing
parameter to create the connection. See Create a new connection on page 28
for more information on creating connections.
Create a new connection
When you import one program you can create a new connection on the last row of
the Connections grid. The new connection connects a program parameter in the
import content to an endpoint connection in a program that is in the project.
Your new connection did not previously exist in the import content nor in the
project. The New Connection row is not available when you import multiple
programs with existing connections between the programs you are importing.
You can type the parameter name for the new connection or click the down arrow
to make a selection from the tag browser. Because only parameters that are in the
import content are valid for the Parameters box, only the parameters that reside
in the import content are listed in the tag browser. For more information about
the tag browser, see
Using the Tag Browser in the online help.
When both the parameter and final connection have been specified, the
connection is made (added) to the connection grid after you move off the New
Connection row or after you press Enter. If you enter an invalid parameter or
final connection, the connection is not created and the error indicator displays in
the leftmost column. Hover the cursor over the error indicator to see a description
for the cause of the error.
