Chapter 2
Additional considerations for rungs
This chapter explains import and export of rungs.
One rung or a contiguous set of selected rungs may be exported to an .l5x file.
The export file may also include any program-scoped tags, controller-scoped tags,
Add-On Instructions, user-defined data types, and user-defined string types that
are referenced by the rungs. The definitions for the referenced tags, Add-On
Instructions, and user-defined data types are exported to the .l5x file if they exist in
the project. In the case of rungs exported from an Add-On Instruction routine,
any parameters and local tags referenced are exported if they exist at the time of
export.
When importing rungs, you configure how the referenced components are
imported during import configuration. By default, referenced components that
collide with project components are not imported.
The following table lists considerations when importing rungs.
Topic Consideration
Pending Edits exist If rungs are imported into a program or equipment phase that contains Pending Edits, all
Pending Edits in the program are accepted if Accept Program Edits is selected during
import of the rungs. Similarly, all Pending Edits in the program are finalized if Finalize All
Edits In Program is selected during import of the rungs.
Accepted Edits exist Rungs cannot be imported into a program or equipment phase that contains routines with
Accepted Edits or Test Edits. Existing edits must first either be assembled or canceled.
First scan When importing rungs into an existing program, the S:FS bit is not set during the next scan
of the program. This applies when importing rungs into an existing equipment phase as
well.
Collision handling If you select Overwrite Selected Rungs in the Import Rungs dialog box, the imported
rungs overwrite the rungs selected in the project.
If Overwrite Selected Rungs is cleared, the imported rungs are inserted before the
selected rungs in the project if the ladder editor is in Insert mode, they are inserted after
the selected rungs if the ladder editor is in Append mode.
