How to Update Vision Library+

Remove Previous Version Files

Navigate to your PI Vision ext folder, located in your PI Vision Installation directory /Scripts/app/editor/symbols/ext. To ensure a clean installation, delete all existing files and folders except for config.js and license.js. Keeping these two files ensures your custom settings and software license remain fully intact.

Extract the New Release

Copy the newly downloaded Vision Library+ .zip file into the ext folder. Extract the contents directly into this directory, overriding any existing files if prompted.

Once the extraction is complete, your final folder structure should look exactly like the image below:

Update Configuration Optional

Your existing config.js file is fully backward-compatible with this update. You only need to edit this file if you wish to configure or enable new symbols introduced in this specific release. Otherwise, keep your file as-is to preserve your current environment settings.

Restart the PI Vision Web App

To apply the new files, you must restart the PI Vision web application. You can do this quickly by typing iisreset into an elevated command prompt (Run as Administrator).

Alternatively, you can manually restart the PI Vision Web App directly within the Internet Information Services (IIS) Manager.

Clear Browser Cache Optional

Modern web browsers aggressively cache symbol files. Because of this, it can take up to 24 hours for the new symbols to automatically appear for your end-users in PI Vision.

To force an immediate update for yourself, open your browser's Developer Tools (press F12), navigate to the Network tab, check the Disable cache box, and refresh the page.
