Via the parameterization (record set 7Fh) you may activate a global diagnostic interrupt
for the module. A diagnostic interrupt occurs when during a process interrupt execution in
OB 40 another process interrupt is thrown for the same event. The initialization of a diag-
nostic interrupt interrupts the recent process interrupt execution in OB 40 and branches in
OB 82 to diagnostic interrupt processing
cessing other events are occurring at other channels that may also cause a process res.
diagnostic interrupt, these are interim stored. After the end of the diagnostic interrupt pro-
cessing at first all interim stored diagnostic interrupts are processed in the sequence of
their occurrence and then all process interrupts. If a channel where currently a diagnostic
interrupt is processed res. interim stored initializes further process interrupts, these
incoming
get lost. When a process interrupt for which a diagnostic interrupt
released is ready, the diagnostic interrupt processing is called again as diagnostic inter-
rupt . All events of a channel between diagnostic interrupt
outgoing
rupt are not stored and get lost. Within this time window (1. diagnostic inter-
outgoing
rupt until last diagnostic interrupt
incoming
for every diagnostic interrupt
occurs.
