The diagnostic data have a size of 12byte and are stored in the record sets
0 and 1 of the system data area.
As soon as you activated the alarm release in byte 0 of the parameter area,
in case of an error record set 0 is transferred to the superordinated system.
Record set 0 has a fixed content and a length of 4byte. The contents of
record set 0 may be monitored in plain text via the diagnosis window of the
CPU.
For extended diagnostic purposes during runtime, you may evaluate the
record set 1 with a size of 12byte via the SFCs 51 and 59.
At a diagnostic task the CPU interrupts the user application and branches
into OB 82. With according programming, you may request in this OB with
the SFCs 51 and 59 detailed diagnostic information and react on it.
After execution of the OB 82, the processing of the user application is
continued. The diagnostic data remains consistent until leaving the OB 82.
