7 bytes standard diagnostic (offset 0 to 6)
User diagnostic:
- 1 byte Interface status (offset 7) common for
- First controller (always present)
* 2 bytes Parametrization Diagnostic
* 5 bytes Output Buffer Diagnostic
- Second controller (if present)
* 2 bytes Parametrization Diagnostic
* 5 bytes Output Buffer Diagnostic
- Third controller (if present)
* 2 bytes Parametrization Diagnostic
* 5 bytes Output Buffer Diagnostic
- Fourth controller (if present)
* 2 bytes Parametrization Diagnostic
* 5 bytes Output Buffer Diagnostic.
