Chapter 4
Additional considerations for programs and
equipment phases
This chapter explains import and export of programs. All topics apply to
equipment phases as well; any exceptions are noted.
A program can be exported to an .l5x file. The exported program includes all of its
program tags and routines, which are imported with the program automatically.
The export file may also include any controller-scoped tags, Add-On Instructions,
user-defined data types, and user-defined string types referenced by the program.
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.
As with other export types, I/O module data type definitions are not exported.
I/O module data types are created within a project when the associated I/O
module is created in the project. On import, program-scoped tags may not be
modified. As a result, if a program-scoped tag aliases an I/O module type tag, the
I/O module must first exist in the project in order to import the program. To
export the program so that it can be imported into a project with another module
type, first alias the program-scoped tag to a controller-scoped tag of a non-I/O
module type, and then alias the controller-scoped tag to the I/O module. These
program-scoped tags can then be created during the import of the program if
necessary.
When you import a program, the program-scoped tags and routines are imported
as part of the program. The Operation, Final Name, Description, and any other
settings of the program-scoped tags and routines cannot be modified; instead, the
Operations are based on the Operation selected for the program.
Programs cannot overwrite equipment phases, and vice-versa. Programs and
equipment phases must have unique names.
You configure how the referenced components are imported during import
configuration. By default, referenced components that collide with project
components are not imported.
