The coding of the status value depends on the active status and diagnosis mode. It is described in
the following tables.
Condensed Status Condensed Status Condensed Status Condensed Status
The "Condensed Status" codes have been defined to allow easier decoding of the information
provided by the PROFIBUS devices. The coding is shown in the following table:
