I have define 2 byte values for in and out direction but when I go on "Edit Symbols" I can only assign names for each bit, not for the complete word. Is there a way to do this? If not how can I convert the 16 individual bits back to an interger? Best regards Stephan

But anyway it's strange that the HW config offers you the declaration of bits instead of word, are you sure that there should be the INT value? Can you pleaseprovide some more information, e.g. what type of slave it is, printscreen of HW config, GSD file... Regards Sydney
