Perform the following steps:
1. In the Save in and File name fields per default the currently defined file location
and file name are already set. If desired browse for another path and/or edit the
file name entry.
2. In the Data type field choose one of the available file types. The selection list
contains for normal projects as well as for library projects all versions of the
programming system for which a project can be stored. If the project should be
opened later in an older version, it is reasonable to store it exactly for this version
because then you will get immediately informed on possible data loss. Regard in
this context also the default project settings for the storage format. Basically there
are two types:
Project files r The project will be saved as a »PLC Designer« project file
"<filename>.project" for the currently used resp. for the selected version of the
programming system.
Library files resp. Library files (»PLC Designer« V<version>): The project will be
saved as a »PLC Designer« library file "<filename>.library" for the currently used
resp. for the selected version of the programming system.
Regard the following before saving that project as a library:
• If the library should later be suitable for getting installed in other projects, enter at
least a title and a version number, optionally (recommended) also a category and
the company name in the Project Information (Summary).
• The saving of a library project does not include an automatic check for errors!
• Regard that in contrast to »PLC Designer« V2.3 there is no more differentiation
between "external" and "internal" libraries. Now you can specify in the properties
of each object, whether it should be handled as "external".
• Consider whether you at once want to install the created library to the System
Library Repository. In this case use command Save Project And Save Into Library
Repository.
• If the library project should be protected against later modifications,
activatevoption Released in the Project Information dialog. This will effect, that
later at the first try to re-edit the library project, an explicit confirmation will be
forced that the modification is really wanted.
If there is already a file with the defined name, a message dialog will open to ask you
whether that file should be replaced. If you choose No, you will get back to the 'Save
Project' dialog described above to select another path. If you are going to save the
project in another version of the programming system than currently used, you will get
made aware of possible data loss.
