Hello hamed;

Compare your list with the one attached below. This Control word description table was taken from the following manual:

https://support.industry.siemens.com/cs/fr/en/view/6586565

In the attached table, note that bit 0 is at the top of the table, bit 15 is at the bottom.

Bit 12, both in your screenshot and in the MM4 control word table, is marked "unused".

You could simply modify your screen, replacing the "-------" line with "Unused", simply to remove any doubts or further questions.

Hope this helps,

Hello Hamed;

Please note that what you call "Bit 4" in actually bit 12 in my table, and in your screenshot.

Hope this helps,
