Package variables

Package variables - Up.identifier
Package variables are variables that only have meaning within the package. The controller
does not know these variables and they are not transferred to the controller.
These variables consist of an identifier, which is preceded by the Up. prefix.
The characters that are also permissible in the NC for identifiers are admissible for the identifier.
Therefore, the same rules as for the NC basically apply (no umlauts, no blanks, etc.).

DO variable
System variable
Package variables are identified by the prefix "Up.". Depending on their definition location,
package variables are classified according to the following categories:
Category
Script
DO (drive object)
System
All package variables are defied in the same namespace. Consequently unique names must
be used throughout all categories. Package variables are addressed using the Up prefix. They
can be used throughout the package, in step scripts, tasks, etc.
They can be used as follows:
● In manipulation tasks for reading as well as writing using Up.identifier
● In step scripts (see: Steps (Page 196)), reading via Up.identifier
● In connection with the replacement operator: $(Up.identifier), see Special
operators (Page 255).
A variable name "identifier" that can be entered by the user must start with a letter or an
underscore and comprises the characters A-Z_0-9. Upper/lower case is not relevant.
Package variables that receive their value from the system can only be accessed in read-only
mode.
