Save trend data to a ​.CSV file

When you save trend data, all data is exported to comma separated values (.csv) format. The .csv file includes all time stamps and values for the tags on the current trend chart at the time of the save.

To save trend data

1. From the File menu, select Save.

2. Select Save data.

   The standard Windows Save As dialog box appears.

3. Browse to the location in which you want to save the file.

4. In the File name box, type a name for the trend data file.

5. Click Save.

You can view the data in any spreadsheet application that can open .csv files, such as Microsoft Excel.

If you do not want the data values to be blank unless the value is NULL, use the Cyclic retrieval style and add the following entry into the win.ini file:
