Structure Of The Interrupt Status Of The Interrupt Section - Siemens SIMATIC ET 200S Manual

Interrupts
If the configuration was done with STEP 7, the interrupt data will be evaluated and
sent to the relevant organization function blocks (OBs).
The interrupt section for the ET 200S is structured as follows:
Byte x
Byte x+1
Byte x+2
Byte x+3
Byte x+4 to...
