 Principle of application pages
 Definition
Application pages are pages designed to provide information about the
control-system architecture being run. They also serve to clarify any
operation that the operator might have to perform in a given context.
Application pages can be interlinked to create authorized sequences
during operation (see chapter C, section Functional links, Page 51).
Unauthorized operators can be prevented from displaying protected
pages (see chapter C, section Protecting a page, Page 28)
 Principle of system pages
 Definition
System pages are predefined pages, which are used to perform
operations relating to the display unit "system".
In run mode, these pages can be accessed in the same way as
application pages.
System pages are pages processed as if they were application type
pages. Hence they are stored with the application pages in the
developed application file.
There are 3 types of system page:
- Standard system pages, which can be called by accessing an
application page (numbers 1 to 100)
- System pages, which cannot be called by accessing an application
page (numbers 101 to 200)
- Popup/message system pages, which cannot be called (numbers 201
to 300)
