Instructions:
You can store tags/data records in CSV file via a script that is executed event-triggered (e.g. by clicking a button).

At the end of this entry is a sample project in which the functionality is implemented. An MP277 Touch operator panel and PC Runtime were used.

The example can be used on all operator panels that support script functions.
 

No.	Procedure
1	Description of scripts used: "Storage_Tag_V1" script The script automatically prefixes the archive with the current date.   The name of the CSV file is "Archive_Date.csv". The script is structured so that the storage path configured is created automatically at Runtime. Therefore, the storage path does not have to be created manually beforehand on the memory card. The "Script_Storage_Path" script executes this function. The script is called by a certain trigger event (e.g. clicking a button). The script first checks whether a memory card (with MP277) is available. If no memory card is available, a system message is issued. If the file to be archived does not already exist on the data carrier, a new file is created. An existing file is opened, the data attached and then the file is closed again. "Script_Storage_Path" script The "Script_Storage_Path" script splits the specified storage path with the "\" character into separate "subfolders" and writes these one after the other to the storage medium. The function is executed until there are no more "\" characters in the storage path. The storage path is transferred as parameter to the "Script_Storage_Path" script (see Script "Storage_Tag_V1" Lines 29 and 21). Note: Do not use the internal memory of the operator panel as storage path. This is not allowed. The VBS functionality gives you a wide range of options for influencing the display and parameterization. You can change the scripts as you wish to suit your requirements. The scripts have "comments" that give brief descriptions of the individual steps. Please refer to the WinCC flexible Online Help or relevant specialist literature for detailed information on the functions and commands used.
2	Program extension/modification: If you wish to change the storage path, for example, or add more tags to application, then make the following changes to the "Storage_Tag_V1" script. You do not have to make any changes to the "Script_Storage_Path" script. Storage path: Line 5: You specify the storage path in Line 5. Extend the table header: Line 13: You extend the "table header" in Line 13. System message: Lines 24 and 43: You change the system message text in Line 24 (MP 277) and Line 43 (PC Runtime). Change/add tags: Lines 51 and 57: You change tags and add more tags in Line 51 (MP 277) and Line 57 (PC Runtime). There is no need for any more changes in the scripts for this application.
3	Function description: Fig. 01 Assign the relevant values via the IO fields (1). Click on the button (2) to execute the "Storage_Tag_V1" script and store the data in a CSV file.

General note:
Note the difference in VBS syntax in Windows CE-based devices and PC Runtime. The commands are sometimes different in these operating systems.
Thus the scripts stored in MP277 Touch cannot be tested in the RT Simulation. 
For this, refer to the information in Entry ID 13408815.
