The two fault groups IOC_FAULT and IOC_SOFTWR faults are Conditionally Fatal to the system (forces the PLC to STOP FAULT mode) whenever the fault that is logged is Fatal to the Genius Bus Controller that logged the fault. When a module logs a fault it notifies the PLC whether or not it can continue by placing Fatal or Diagnostic in the fault action of the fault entry. The PLC will shut the Genius Bus Controller down on all Fatal faults.
Note
In a CPU redundancy system a Fatal fault from a GBC will cause the active unit to transition to STOP FAULT mode. All Diagnostic faults will allow the CPU to continue to operate.
