Definition
A diagnostics interrupt is an alarm that reports activated events of a device status to the system
operator with the appropriate operating authorization (maintenance and service).
Description
The interface module supports diagnostics interrupts:

• Module parameter errors or incorrect carrier present in real slot
• Failure of redundancy partner
• Impermissible bus adapter on interface module
• Incorrect bus adapter in redundancy partner

• Different hardware/firmware in the redundancy partners
• IO redundancy warning
• Redundancy parameter assignment inconsistent
