Description Note
(Bit)
RY Ready
0: Logging is enabled (in the case of ring buf-
fers, RY = 0 always)
1: Logging inactive
Logging can be disabled because:
l n log files have been written
l The memory card is full
l No memory card inserted
l Memory card faulty
BY Busy
1: Logging not possible
Possible causes:
l The card is currently being written to
l The temporary internal buffer is full
E1 Error output
1: Data loss
Possible causes:
l No memory card inserted
l The memory card does not have
enough space for another log file
l Memory card faulty
l Temporary internal buffer overflow
by at least one record
