Importing and Exporting Add-On Instructions

When you export an Add-On Instruction, the exported Add-On Instruction

includes all of its parameters, local tags, and routines. These will be imported with

the Add-On Instruction automatically.

Optionally, you can include any nested Add-On Instructions or User-Defined

Data Types that are referenced by the exported Add-On Instruction. Referenced

Add-On Instructions and data types are exported to the L5X file if you check

‘Include all referenced Add-On Instructions and User-Defined Types’ during the

export.

Add-On Instruction definition references may also be exported when a program,

routine, set of rungs, or User-Defined Data Type is exported.

Tip: If an Add-

On Instruction uses Message (MSG) instruction and InOut parameters of type MESSAGE, you may

wish to export a rung containing the Add-On Instruction to include the MESSAGE tags. This captures the

message configuration data, such as type and path.

In deciding how to manage your Add-On Instruction definitions in export files,

you need to consider your goals in storing the definitions.

If Then

You want to store many Add-On Instructions that share a set of common

Add-On Instructions or User-Defined Data Types in a common location

Export to separate files as described on

page 86 on page 91.

You want to distribute an Add-On Instruction as one file

Export to a single file as described on page

87 on page 93.

You want to manage each Add-On Instruction as a standalone instruction

You want to preserve the instruction signature on your Add-On Instruction

Tip: Add-On Instructions with instruction

signatures are encrypted upon export to prevent modifications to the

export file.

Exporting to separate files

If you want to store many Add-On Instructions that share a set of common

Add-On Instructions or User-Defined Data Types in a common location, you

may want to export each Add-On Instruction and User-Defined Data Types to

separate files without including references.
