5.9 Diagnostic and interrupt5.9.1 OverviewThe parametrization allows you to define the following trigger for a hardware interrupt:n Edge at an digital interrupt inputn Reaching the comparison valuen Overflow respectively at overrun upper counter limitn Underflow respectively at underrun lower counter limitn Opening the HW gate with open SW gate - except for counter 3n Closing the HW gate with open SW gate - except for counter 3The VIPA specific parameters allow you to define the following trigger for a diagnosticsinterruptÄ Chapter 4.8 ‘Setting VIPA specific CPU parameters’ on page 66:n Hardware interrupt lostn Error: 4L+ DC 24V DO power section supplyn Error: 3L+: DC 24V DI power section supplyn Short circuit overload: DO5.9.2 Process interruptAn interrupt for the corresponding channel operating mode can only betriggered if you have additionally parameterized ‘Diagnostics+Process’ at‘Select interrupt’ of the ‘Basic parameters’ .A process interrupt causes a call of the OB 40. Within the OB 40 you may find the logicalbasic address of the module that initialized the process interrupt by using the Local word6. More detailed information about the initializing event is to find in the local double word8. The assignment of local double word 8 depends on the parameterized operating modeof each channel.Hardware interruptDiagnostics interruptVIPA System MICRODeployment I/O peripheryDiagnostic and interrupt > Process interruptHB400 | CPU | M13-CCF0000 | en | 16-47128
