Structure of Additional Interrupt Information with Interrupts from PROFINET IO,
Case 2
The additional interrupt information for PROFINET IO depends on the format
identifier. If information on channel diagnostics is to be transmitted, the IO device
uses the format identifier W#16#8000.
The channel diagnosis is output in blocks of 6 bytes each. The additional interrupt
information (with out format identifier) is only output for faulty channels.
