Examples to access the application database
To read a value in the database, use the tag name directly.
Example 1:
In the following script line, the X tag will receive the sum of two tags, level and temp:
Example 2:
InduSoft Web Studio allows you to read and write in the tags using references or pointers. A tag
used as pointer to another tag can be declared in two ways: as a string (a pointer to an undefined
type) or as a pointer of a specific kind (recommended).
In Figure above, the pointer_default is a variable of the string type that is a pointer. The variable
@pointer_to_integer is a pointer to integer values.
NOTE: The syntax @tag allows a tag to access another by reference.
NOTE: Any tag declared as a string can be used as an indirect tag (pointer).
