5.2.4 Operation When the Card Cover of CPU Unit Opens
The following operations are performed when the card cover is open during the trace
operation.
Operation of system relays
The logging/trace active flag and the SD card logging active flag stays on while the card
cover is open.
Although the logging/trace active flag turns off once the trace stop condition is met, the SD
card logging active flag stays on.
When the card cover is closed, the SD card logging active flag also turns off.
The logging operation into the logging buffer (RAM) continues even when no SD memory
card is inserted. Once the logging buffer (RAM) becomes full, the buffer overflow flag turns
on.
File status in SD memory card
If data cannot be written into an SD memory card after the completion of trace, the
logging/trace error flag turns on, and the operation ends.
