The contents of the interrupt information depend on the interrupt type:
● In the case of diagnostics interrupts, diagnostics data record 1 (up to 58 bytes) is sent as
interrupt status information (starting from byte x+4).
● The length of the interrupt status information for hardware interrupts is 4 bytes.
The figure below shows the structure of the interrupt section for the ET 200AL distributed I/O
