Code for Length of user messages:
device-related diagnostics 2 ... 63 relates to 2 ... 63 Bytes
If the length entered in DW 0259 is greater than 2, the user messages will
follow on from DW 0260 (Byte 9). If the length entered is less than 2,
device-specific diagnostics will not be possible.
Contents of data word DW 0259 DL: Byte 8:
In DW 0259 DL the PSS(1) DP-S or PSS SB 3006 DP-S registers whether
the PSS standard section is in a RUN or STOP condition (see page 4-4).
The length of the diagnostic data must be entered in DW 0812. This is
composed of:
3 words of internal diagnostic data (DW 0256 +DW 0257+DW 0258)
+ 1 word of device-specific diagnostic data (DW 0259)
+ x words user-specific data.
