Attribute ‘no_check’

This pragma prevents the check function being called for the POU (POUs for implicit checks). Since the check functions can affect the processing speed of the program, it can be useful to apply the attribute to function blocks that have already been checked or are frequently called.

You add the pragma to the declaration of a POU.

Syntax:

{attribute 'no_check'}

Insertion position: first line in the declaration part of the POU.

Attention

The attribute also automatically affects the child objects of a POU!

Example: If the attribute is entered in a program, check functions will also not be carried out for actions that are assigned to this program.
