Diagnostics data record DS1
The diagnostics data record DS1 consists of 16 bytes. The first 4 bytes are identical with
those of diagnostics data record DS0. The table below shows the assignments of the
remaining bytes. Any bits not listed bits are insignificant, and zero. FC DIAG_INF writes this
data record to the DB of FC CNT_CTRL1, starting at DW54.

How to enter diagnostics messages in the diagnostics buffer
If you want to enter the diagnostics message in the diagnostics buffer, you must call the
SFC 52 "Enter user-specific message in diagnostics buffer" in your user program. The event
number of the diagnostics message is defined at input parameter EVENTN. The interrupt is
identified by the entries x=1 as incoming and x=0 as outgoing event in the diagnostics buffer.
The diagnostics buffer contains the relevant diagnostics text entry in the `Meaning' column,
including the time of its entry.
Defaults
The diagnostics interrupt is disabled by default.
