How to convert .HST data files to .CSV format?

Question

Hi,

I have several trend history files in .HST format. Please could anyone advise how to convert them into .TXT or .CSV for further analysis?

Citect SCADA version is 7.4.

Thank you in advance for any response. Regards, Jen

To convert .HST data files from CitectSCADA to .CSV format, you will typically need to use CitectSCADA's exporting tools or third-party software that can read these proprietary files. While CitectSCADA itself may not provide a direct method to export historical files as .CSV, here are some steps you can try:

1. Use CitectSCADA's built-in tools:

   • Open CitectSCADA and access the Trend feature.
   • Use the built-in reporting or export features to extract the trend data. Verify if it allows export to your desired format (possibly .TXT or .CSV).

2. Custom script or utility:

   • If you have programming experience, or access to someone who does, you could write a script to read the binary .HST files and convert them to a plain text format like .CSV. This can be done using Python or other scripting languages, provided you have a detailed specification of the .HST file format.

3. Third-party tools:

   • Seek out third-party software specifically designed for CitectSCADA that offers file conversion features. Ensure that the tool supports your version, 7.4, and that it can output to .CSV.

4. Consult CitectSCADA support:

   • Contact CitectSCADA support or check their forums/documentation. There may be existing solutions or plugins created by the community or support team to meet this need.

Keep backups of your original .HST files before attempting conversions, as the process might alter data if not done with appropriate tools.
