When the data storage destination memory is the function memory
The following figure shows the flow of data when the data storage destination memory is the function memory.
(1) The collected data is temporarily stored in the specified internal buffer. ( Page 188 Internal buffer)
(2) The data stored in the internal buffer is stored into the function memory at the timing of a file save operation.
(3) With the file transfer setting, data logging files can be transferred from the function memory to the FTP server. ( Page 194 Data Logging File Transfer
(Auto Transfer to FTP Server))
(4) Without the file transfer setting, data logging files are transferred to the data memory upon completion or stopping of the data logging (including when an
error occurs). ( Page 202 Data Logging File Transfer to Data Memory)
