Backing up the diagnostics
Depending on byte x+1, transfer the content of the device-related diagnostics for the following
reasons to a data block
● The interrupts are updated cyclically.
● The content of the diagnostics starting from byte x+3 depends on whether a diagnostic
interrupt, hardware interrupt, or plug/pull interrupt is signaled.
Note
In order to evaluate diagnostic interrupts and hardware interrupts via the device-related
diagnostics, you must regularly query the corresponding bits in the device-related
diagnostics in your user program.
