6.1 Operations When Errors Occur

6.1.1 Operation When Power Supply Turns Off

 Operation When Power Supply Turns Off
• While the logging/trace buffer logging/file writing is performed (R9179 is on), the power off
flag during SD memory card access flag (R917F) turns on.
• The data stored in the buffer of the control unit will be discarded.
•
In case of the middle of file writing, written data or files may be damaged, or
the SD memory itself may not be read.
6.1.2 Operation When Errors Occur (Only When Selecting Logging for
Application)

State
When multiple data are logged in
one second
When time data was turned back
 Operations when reactivating the power supply
State
When a current file with 0 record
exists
When a current file with N records
exists
 Operation when log data is zero and file determination is requested

Operation
Create an error file with the following file name, and exclude them from the
target for generation management.
File name (Date_Time_ERR).csv
If the same file is created, discard the current file and continue the logging
operation.
If detecting that time is turned back from the previous record in logging
operation, it is regarded as a file determination trigger, and a file with the
following file name is created and excluded from the target for generation
management.
File name (Date_Time_TIM).csv
The logging operation continues.
Operation
Newly create a current file based on the file definition.
Newly create a current file based on the file definition after determining the
current file.
The determined file name is "file name (date_time_POW).csv, and it is
excluded from the target for generation management.
