4.2 Operation When Logging is Selected for Application

4.2.1 Operation When Logging Operation is Started

The following operations are executed when the start operation is requested.
• Registered data is confirmed.
• Once the logging/trace becomes executable, the logging/trace execution active flag
(R9180/R9190/R9200/R9210) turns on. When the logging trigger condition is met under this
condition, the logging/trace operation starts.
• All logging/trace control relays other than the logging/trace execution active flags for LOG n
(R9180/R9190/R9200/R9210) are cleared once during the start request operation.
• Once writing data into an SD memory card becomes enabled after the logging/trace
execution active flag (R9180/R9190/R9200/R9210) turned on, the SD card buffer logging/file
writing active flag (R9181/R9191/R9201/R9211) turns on.
• When an SD memory card that can be normally read and written is not inserted, or the
battery cover is open, an operation error occurs.

4.2.2 Operation When Logging Operation Stops

 Operation when switching from RUN mode to PROG. mode
• All logging operations stop.
• All information saved in the buffer memory of the control unit is written into a file, and the file
is determined.

4.2.3 Operation When Power Supply Turns Off

 Operation When Power Supply Turns Off
• When activating the logging/trace function, the power off flag during SD memory card access
(R917F) turns on.
• The data stored in the logging 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.
