Structuring a Complete (.L5K)
Import/Export File Format
Introduction
This chapter explains the overall structure of a complete
import/export file. The file extension for a complete import/export file
is .L5K.
For information about the specifics of each component in an
import/export file, see the chapter “Creating an Import/Export File”.
For information on entering logic, see the chapter “Entering Logic.”
Conventions
The import/export utility is based on the formats specified by the
IEC 1131-3 specification. The examples follow these conventions:
White space characters include spaces, tabs, carriage return, newline,
and form feed. These characters can occur anywhere in an
import/export file, except in keywords or names. If white space
characters occur outside of descriptions, they are ignored.
Internal file comments
You can enter comments to document your import files. The import
process ignores these comments. You can place comments anywhere
in an import/export file, except in keywords, names, component
descriptions, and the value portion of attributes (before the delimiting
comma or the end parenthesis).
Convention: Meaning:
< >
items shown in angle brackets are required
[ ]
items shown in square brackets are optional
user_value
items in italics indicate user-supplied information
LITERAL
items in all uppercase indicate a required keyword
or symbol that must be entered as shown
“[“
items in double quotes are required characters
