Byte Y+4 To Y+7 For The Diagnostic Interrupt - Siemens SIMATIC ET 200S Manual

Structure of the interrupt data with process interrupt (from Byte y+4 onwards)
With the process interrupt (in byte y+1, code 02
the 4 byte interrupt information which you transfer in the intelligent slave with the
SFC 7 "DP_PRAL" and SFB 75 "SALRM" when the process interrupt is generated
for the master, is transferred from byte y+4 onwards.
Structure of the interrupt data when a diagnostic interrupt is generated by a
mode change at the intelligent slave (from Byte y+4 onwards)
In the byte y+1, the code stands for diagnostic interrupt (01
contains the 16 byte status information for the CPU. The following figure shows the
assignment of the first 4 bytes of the diagnostic data. The next 12 bytes are always
0.
The content of these bytes corresponds to the content of data record 0 for
diagnosis in STEP 7 (in this case not all bits are assigned).
