  • Page 117: Appendix D: Self Supervision

    Level 1 faults are irrecoverable fatal errors. After fault detection, the system is not able to guarantee safe execution of the protection and control functions. The irrecoverable fault forces REF 542plus to stop any activities and it can only be restarted after a power-switch cycle (power off/on) or after a configuration download (if possible).
  • Page 118 SPA event Supervision by bootloader REF 542plus has an on-chip bootloader that handles the software upgrade and the entering into Factory test mode. The bootloader supervises RAM (Random Access Memory) and FLASH (MC non-volatile memory) application program correctness.
  • Page 119 If the fault is not reproducible, a special REF 542plus SW can be built that is able to make a trace log of all the activities executed by the SW (interrupts, tasks switching, events, semaphore, etc.).
  • Page 120 Fatal errors Fatal errors are faults detected by the internal error checking functionality that, if it fails, compromises the system reliability (e.g. RTOS errors). The REF 542plus fatal error handler stores a fatal error description string in the internal memory.
  • Page 121 Operator's manual Note that all version checks are performed by REF542CONF before configuration download. Therefore, the fault can occur only after a REF 542plus firmware upgrade/downgrade or after FLASH configuration data corruption. The following table describes signalling/handling of the configuration faults:...
  • Page 122 DSP communication COM module (optional extension) The COM module is an optional module that can be installed in the REF 542plus housing. Its supervision is done only if the COM module is detected at start-up or configured by REF542CONF. The supervision verifies correct COM module configuration start-up and correct COM working status during normal operation.
  • Page 123 AI20mA module (optional extension) The AI20mA (20 mA analogue input module) is an optional module that can be installed in the REF 542plus housing. Its supervision is done only if the AI20mA module is detected at start-up or configured by REF542CONF. The supervision verifies correct AI20mA start-up and correct AI20mA working status during normal operation.
  • Page 124 SPA event “102E54” (command failure) FLASH data REF 542plus uses a FLASH device to store non-volatile data/configuration. The MC supervises every FLASH erase/write operation checking that the FLASH status registers. In order to protect the FLASH data against erroneous write/erase attempts, the FLASH is write-protected which means that erroneous access will raise a SW exception (address error).
