Attribute: obsolete

The effect of this pragma is that a defined warning is displayed for a data type definition during compilation if the data type (structure, function block, etc.) is used in the project. This enables you, for example, to draw attention to the fact that a data type is no longer valid because, for example, an interface has changed and this should also be implemented in the project.

In contrast to a message pragma this warning is defined centrally for all instances of a data type.

Syntax:

{attribute 'obsolete' := 'user defined text'}

Insert location: Line of the data type definition or in a line above it.

{attribute 'obsolete' := 'Data type FB_I1 not valid'}
FUNCTION_BLOCK FB_I1
VAR_INPUT
    i:INT;
END_VAR
;
