Error statistics of the digital FI control
The lower display row reports the occurred errors of three different
error types.
§
Number of NAK errors: the FI has sent an NAK (not
acknowledged), i.e. the FI has not accepted the last command
(transmission error, …).
$
Number of proof total errors: the proof total of the received FI
messages is wrong (transmission error, …).
%
Number of Timeout errors: the FI has not answered within the
Timeout period (60 ms).
Note: At each emergency-stop the number of timeout errors is
increased compulsorily by at least one numerator, because the
transmission line to the FI is being interrupted by hardware.
