Diagnosis telegram in professional mode
The diagnosis telegram contains 24 bytes in the professional mode. The structure is
represented in the following table.
execution control flags see appendix, chapter 11.2.
The configuration error list is built up as the LPS (see appendix, chapter 11.1). A bit
in the configuration error list is set, if the concerning bit in the LPS (List of Projected
Slaves) differs from the one in the LDS (List of Detected Slaves) or if the projected
AS-i configuration data (I/O- and ID-code) of the concerning AS-i slave differ from the
detected configuration in the AS-i circuit.
The LCS is explained in chapter 7 (advanced AS-i diagnostics).
