Data is offset after switching from AB7654 to AB7649


After they switched from the AB7654 (ControlNet to Profinet IO) to the AB7649 (EIP to Profinet IO) their data is offset by one byte and they would like to know what caused this.



Hi Philip,

This is actually fairly common, but without seeing the configurations it would be hard to speculate what caused it.

Is it possible that you were using a control/status word with one config and not the other? If you are using a scan list, check and make sure that they match up.
