6.13.1 Process interrupt
A process interrupt causes a call of the OB 40. Within the OB 40 you may find the logical
basic address of the module that initialized the process interrupt by using the local word
6 . More detailed information about the initializing event is to find in the local double word
8 .
The local double word 8 of the OB 40 has the following structure:
Local byte Bit 7...0

6.13.2 Diagnostic interrupt
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-
