Chapter 4 Importing and Exporting Add-On Instructions
Tip: You can only rename an Add-On Instruction if it has not been sealed with an instruction signature.
To rename an Add-On Instruction that has been source-protected, you need the source key.
The Collision Details button lets you view the Property Compare tab, which
shows the differences between the two instructions, and the Project References
tab, which shows where the existing Add-On Instruction is used.
When you need to update an instruction to a newer revision, you can import it
from an L5X file or copy it from an existing project. You must be offline to update
an Add-On Instruction.
Follow these steps to update an Add-On Instruction to a newer revision by
importing it.
1. Right-click the Add-On Instruction folder and click Import Add-On
Instruction.
