Installation Guide

How to install custom symbols and extensions to AVEVA PI Vision (formerly Coresight).

1. Deploy Files

Extract the downloaded ZIP archive. You will see HTML, JS, and image files.

Copy these files to the PI Vision server directory:

%PIHOME%\Scripts\app\editor\symbols\ext

Typically, this path translates to:

C:\Program Files\PIPC\PIVision\Scripts\app\editor\symbols\ext

2. Unblock Files (Important!)

Windows often blocks downloaded files for security. Before copying, or immediately after:

  • Right-click the downloaded .js or .html file.
  • Select Properties.
  • Check the Unblock box at the bottom right.
  • Click Apply and OK.
Note: If you skip this, the symbol might not load in the editor.

3. Troubleshooting

Clear Browser Cache

If the symbol doesn't appear in the asset pane:

  • Press Ctrl + Shift + R to hard refresh your browser.
  • Or verify that the files are in the correct ext folder.

Restart IIS (Optional)

In rare cases, PI Vision might rely on cached scripts server-side. If issues persist:

iisreset

Run this command in PowerShell as Administrator.
