Wow - Now it's working.

I think this needs definitly to be added to the standard pragma attribute list, because I didn't find it there.

Cheers,

With the installation of the Full Static Analysis functionality, you get a Add-On help topic in the online help.
This describes the way how to deactivate specific rules.

For unused variables, which is SA0033, you can use:

   {attribute 'analysis' := '-33'} 
   itf_MyFB         : itf_FBExtended := THIS^;
   {attribute 'analysis' := '+33'}

This way, if i is not used, this is ignored by static analysis.
- is turning it off
+ is turning it back on

Hello Community,

under projectsettings --> static analysis light, I enabled 'check for unused vars'.

So If I declare an output var like this:

VAR_OUTPUT
   itf_MyFB         : itf_FBExtended := THIS^;
END_VAR

I allways get a Static analysis error:
SA0033: unused var ....

How to avoid this message? I know, that there is an attribute to exclude warnings, but for Static Analysis I've nothing found in the online Help.

Thank you in advance.
