Attribute: no_check

The pragma has the effect that the check function (POUs for Implicit Checks) is not called for for the POU. 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'}

Insert location: First line in the declaration part of the POU

Important

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 performed for actions that are assigned to this program.
