REQUEST
The tag is used to add a variable to the cyclic reading service (hotlink). As a consequence,
the access time to variables, which are not linked to the control, is reduced.
If a function is to be called automatically when a value changes, then the name of the func-
tion should be specified as an additional attribute.
This tag is only processed within the INIT operation.
Attributes:
•
name
Address identifier
•
function
Function name
Syntax:
<REQUEST name = "<NC-Variable>" />

<function_body name="my_function" >
<print text="value changed" />
</function_body>
