Changing/Expanding Screens
Before changing and/or expanding screens, you should consider the pre-defined structure of the
application screens. For new screens, you can use existing screens (including the Standard screen),
saving it under different names. To update/change an existing screen, insert/change the objects in the
window between the header and footer. It is not recommended to change the header or footer
arrangement itself.
The standard header and footer was used as template for all application screens. The footer area
includes a single line alarm object that displays the latest active alarm. The individual objects that make
up graphics, faceplates, etc. on the application screens are taken from the pre-configured objects in the
Library.
Database Updates/Additions Recommendation:
For most applications there are no update or addition requirements of the pre-defined Tags that are
stored in the Application Database. Or in other words, the pre-defined generic Application Database
does not have to be changed in most cases; user tags are accommodated by tag labels (not database tags)
‘drawn’ with the screen editors’ A/N characters.
If updating/changing Application Tags is required, keep the following syntax rules in mind:
• Although the maximum Tag length is 32 characters, Tags should be as short as possible
(typically not exceeding 12 characters)
• Tags must begin with a letter. They can be composed of letters, numbers, and the underscore
character (_)
• The tag name must be different from the Web Studios’ reserved internal tag names and math
functions
• While tag names are NOT case sensitive, both uppercase and lowercase characters should be
used to make tag names more clear
Make sure that No DRAG is set before working with any screen (see screen, lower right-hand
corner DRAG status). Enable DRAG (strike Ctrl > D on keyboard) only if you need to move/reposition
objects on the screen.
