Logging Operation
4.2 Operation When Logging is Selected for Application
4.2.1 Operation When Logging Operation Starts
The following operations are executed when the start operation is requested.
Registered data is confirmed.
Once the logging/trace becomes executable, the logging/trace active flags (SR100, SR110,
SR122 ...) turn on. When the logging trigger condition is met under this condition, the
logging/trace operation starts.
All other flags than the logging/trace active flag for LOG n are cleared during the start
request operation.
Once writing data into an SD memory card becomes enabled after the logging/trace active
flags (SR100, SR110, SR122 ...) turned on, the SD card logging active flags (SR101, SR111,
SR112 ...) turn on.
When an SD memory card that can be normally read and written is not inserted, or the card
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 CPU 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 logging/trace, the power off flag during file access SR3F turns on..
The data stored in the logging buffer of the CPU unit is discarded.
NOTE
In case of the middle of file writing, written data or files may be damaged, or
the SD memory itself may not be read.
