The shut-off message to the shut-off coordinate due to an irregular combustion EngMon stShOffIrrcmb always has the value 0,The bit position zero of EngMon stShOffIrrcmb is defined for the error“irregular combustion”
Tip:This is implemented as a platform element in the EDC16 Basis,For the Basis,the message for irregular combustion(i.e. EngMon¬¬¬——stShOffIrrcmb.0)is 0
Overrun monitoring has the task to monitor safety—relevant signal paths of the operational layer(layer1)by generating an independent information path within the function monitoring(layer2),Layer2 differs from the application software by additional monitoring mechanisms such as storing of complements of static variables。Program flow monitored and usage of redundant library function。 The calculations of safety—relevant paths are monitored at selected operating points via plausibility checks on input and output variables using a redundant algorithm。
