25.12.5 Saving to CSV

There are two save operations for external storage devices:

Normal Save

When the command is written to the [CSV Control Word Address], data stored in the display unit is output as a CSV file.
25.7.2 Operation - Normal Save

Automatic Save

When the defined number of samples are stored in the display unit and the sampling cycle is complete, data stored in the display unit is output as a CSV file. This option is available when in the [Mode] tab, [Extended] dialog box, you select the [Overwrite old data after finishing the specified cycles] check box.
25.7.3 Operation - Automatic Save

CSV Control Word Address

This address controls writing data to external storage. It writes a command to the address after designating a file number.

Command/Status

After you specify the file number and write the command to the control address, data is output to the external storage. The processing results (status) are reflected in the address.

Mode	Word Data	Description
Command	0001h	Normal Save
	0020h	Start Auto Save (Only when data is stored by overwriting old data ^*1)
	0021h	End Auto Save (Only when data is stored by overwriting old data^*1)
Status	0000h	Completed Successfully
	0100h	Write Error
	0200h	External storage is not connected. The CF Card cover is open. The SD Card is write-protected.
	0300h	No data to be loaded
	0400h	File Error
	2000h	The display unit is in the normal Auto Save mode. While the [CSV Save Control Address] has this value, the Auto Save action continues. When the value changes, the Auto Save mode finishes.

^*1 For methods to store data, refer to 25.12.3.2 Data Storage Methods.

If you write a value (command) other than "0021h" (Auto Save Exit) or change the file number during the Auto Save process (status "2000h"), Auto Save aborts and data up to then is written to the external storage. The write command is not processed. The status will show successful completion "0000h".
When a value other than "0001h", "0020h", or "0021h"is written in a command or the value "0021h" is written instead of "0020h", it will cause a write error "0100h".
When the Auto Save command "0020h" is written in the sampling group without the selection of the [Overwrite old data after finishing the specified cycles] check box, "0300h" error occurs.

File Number

Designates the ***** portion in the file name, "SA*****.csv", when saving to the CF Card/USB storage. The file number can be from 0 to 65535. Set the file number before writing the command.

The CSV File is saved to the folder created in the external storage automatically. The folder is created with a fixed folder name for each sampling group.

Data to be saved	Folder	File Name
Sampling Group 1 data	\SAMP01	SA*****.CSV
