I'm assuming no, but just double checking with you guys... We at the plant need a backup for an application incase the ignition server goes down, is there a way to have a vision application run without a connection to the vision server. ---

I don't believe it's possible to run the application without a connection. The application needs to be connected to read tags, and gather data so even if you could you wouldn't be reading any data. You should look into setting up a redundant gateway see more here: > **[Ignition Redundancy | Ignition User Manual](https://www.docs.inductiveautomation.com/docs/8.1/platform/ignition-redundancy?gad_source=1&gclid=CjwKCAjwgdayBhBQEiwAXhMxtsF9H3ajhfBZP44r78xjs7ULWR_2SqMPFbhNHJ5YDpstCHnl6WDxIRoCVEwQAvD_BwE)** > > Ignition redundancy supports a 2-node system, meaning there are two copies of the Gateway running. One node is the Master Gateway and the other is the Backup Gateway or backup node. All projects, Gateway settings, etc., are shared between nodes.

There's also the local client fallback for this scenario, but like redundancy it involves a second gateway: [Local Client Fallback | Ignition User Manual](https://www.docs.inductiveautomation.com/docs/8.1/ignition-modules/vision/local-client-fallback) ---

Thank you guys!
