INFORMATION
In the case of device-related diagnostics without user-specific messages,
DW 0259 DR will always contain 02.
The PSS(1) DP-S or PSS SB 3006 DP-S registers in DW 0259 DL:

0: ST section of PSS in RUN mode
Not used 1: ST section of PSS in STOP mode
The PSS(1) DP-S or PSS SB 3006 DP-S uses a hardware signal to detect
whether the PSS standard section is in a RUN or STOP condition.
INFORMATION
This type of diagnostics is only possible if the slave has been fully
initialised by the PSS and has been recognised by the Master.
The length of the diagnostic data must be entered in DW 0812. Diagnostic
data has a length of at least 4 words:
3 words of internal diagnostic data in DW 0256, 0257 and 0258
+ 1 word in DW 0259 (as described).
