5.9.3 Diagnostic interrupt
An interrupt for the corresponding channel operating mode can only be
triggered if you have additionally parameterized ‘DiagProcess’ at
‘Select interrupt’ of the ‘Basic parameters’ .
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
incoming
. If during the diagnostic interrupt pro-
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
incoming
is processed res. interim stored initializes further process interrupts, these
get lost. When a process interrupt for which a diagnostic interrupt
incoming
has been
released is ready, the diagnostic interrupt processing is called again as diagnostic inter-
rupt
outgoing
. All events of a channel between diagnostic interrupt
incoming
and diagnostic inter-
rupt
outgoing
are not stored and get lost. Within this time window (1. diagnostic inter-
rupt
incoming
until last diagnostic interrupt
outgoing
) the SF-LED of the CPU is on. Additionally
for every diagnostic interrupt
incoming
/
outgoing
an entry in the diagnostic buffer of the CPU
occurs.
