Import and export Add-On Instructions Chapter 6
makes it easier to maintain the instructions because you have to update only one
export file.
To use Add-On Instructions that were exported in a separate file without
references, you must first import any user-defined data types of Add-On
Instructions that the exported instruction references before the import of the
referencing instruction can be successful. This assumes that the referenced user-
defined data types of Add-On Instructions do not exist in your project. To do this,
work from the bottom up. Import the lowest-level user-defined data types and any
user-defined data types that reference them. Then, import the lowest-level Add-
On Instructions, followed by any Add-On Instructions that reference those low-
level Add-On Instructions. Once all items referenced by the Add-On Instruction
are in place, the import of the Add-On Instruction succeeds.
Export to one file
If you manage each Add-On Instruction as a standalone, you can export the
instruction and any referenced Add-On Instructions or user-defined data types
into one export file. By including any referenced Add-On Instructions or user-
defined data types, you also make it easier to preserve the instruction signature of
an Add-On Instruction.
Follow these steps to export to one file and include any referenced items.
1. Right-click the Add-On Instruction in the Controller Organizer and
choose Export Add-On Instruction.
