1.4 Saving and Deleting Data
●
Saving Data
The save location for sampled data differs according to the model. The save locations are as follows.
If the saved data exceeds the Data Log data storage amount per device, the old data is deleted and the new data is saved.
Data Storage Amount
When saving the sampled data to the data storage area, set the data storage amount per device. The amount of data
that can be saved in the data storage area is calculated from the configured data storage amount per device and data
amount for each channel.
The maximum amount of data that can be saved in the data storage area is as follows.
If sampled data is not saved in the data storage area
, the maximum amount of data in the Data Log overall is
131,072, and the maximum amount per device is 1,024.
