Hi,

I would like to "invert" the bits attribution of a Word like if MW0 = 1 it goes from :

(M0.0 to M1.7) 00000000 10000000 to 10000000 00000000

And then if MW0 =  256 : bits = 00000000 10000000.

Is there a function to do that directly or should I switched it manually in the program ?

Thanks by advanced,

BR

Hi Lucas,

Are you talking about swapping byte order? If so, it should be possible to do this with built-in functionality. However, it depends on the CPU you are using, and that is one of the pieces of information I am missing from your post. But in case of S7-300/400 have a look at "CAW" or in case of S7-1200/1500 have a look at "SWAP".

Kind regards
Stefan

 Exactly what I was looking for, thank you very much
