You can use the built in functions to send a CSV file:
HMI button sets a bit-->
"Store DTI to File" Make sure to set "F" to 1 so it saves a CSV file onto the SD card-->
Then when the "H" status finishes (1-->0) you can use the built in "FTP Send" to send that CSV file you named in the "Store DTI to File"
Then go find it and open in Excel (import as CSV).
Now if you want to import it back into the PLC after you make changes to the file you need to reverse this process:
save as CSV (on computer)
"Convert CSV to UDTF"
"Load DTI from File"
