4.9.2 Service menu: F3 UFC errors window
Under normal circumstances it is not necessary to view this window.
All data shown here is also available in more common used windows in perhaps other formats or
condensed into less variables.
The status is shown as counters per channel.
There is no history in the counters so previous occurred errors will turn to zero.
Communication errors per communication message (=per channel request):
•
Parity errors
•
Error in message length
• Wrong start bytes
• Framing error UART
Communication status sublimated from communication errors per channel:
•
Channel state = 0: no errors (status normally)
• Channel state = 1: error resulting in a single communication failure (COMFA)
• Channel state = 2: comm. failures in succession resulting in a communication alarm (COMMU)
Communication status regarding data skipped or already handled:
•
Old data : Counter for data, already handled(Note: normally toggles between 0 and 1).
• Overrun : Counter for data, skipped because of system time shortage (note: cumulative!).
