Logging data area
Low speed
This area stores the data logged with the normal logging function. The area of 90000 points can be distributed to each
channel by setting 'CH1 Logging data points setting' (Un\G536). After the number of stored data points reaches the points set
in 'CH1 Logging data points setting' (Un\G536), data is continuously collected overwriting the data in the start address and
later.
For details on the normal logging function, refer to the following.

• When 'Operating condition setting request' (Y9) is turned on, the logging data in all the channels are
cleared.
• When 'CH1 Logging hold request' (Y1) is turned off while 'CH1 Logging hold flag' (Un\G409) is on, data
logging resumes. In this case, the logged data is not cleared.

■Updating data
The update timing of this area varies depending on the operation mode.
• In the simultaneous conversion mode, data is updated every time logging 5000 points of data is completed.
• In the inter-module synchronization mode, data is updated at every inter-module synchronization cycle.
When 'Operating condition setting request' (Y9) is turned on, the logging data in all the channels are cleared.
