Storage operation mode (linear buffer)
In this mode, sampling is performed only for the logging data size after logging has started. This is used when the logging
period is clear before logging starts.

Operation examples for when the following parameters are set are shown.
• "Logging function enable/disable": "Enable"
• "Logging operation mode setting": "Storage operation mode"
• "Buffer operation setting": "Linear buffer operation"
• "Select logging start control": "Register setting value (RY3)"
• "Select sampling pulses": "Logging cycle timing"
• "Logging cycle timing": "100s"
• "Logging data size setting": "16384 records"

 Turn off and on Logging start request (RY3) at any time to start logging. When logging starts, the status of Logging operation state monitor (RWrB) becomes
Collecting (2H) and Logging start flag (RX3) turns off and on.
 After logging starts, sampling takes place every "100s", as was set for "Logging cycle timing".
 After a number of samples that meets the logging data size setting has been sampled, logging stops and Logging operation state monitor (RWrB) changes to
FTP transfer in progress (4H).
