Store and Forward with SQL Bridge at Remote Location

Hello,

I'm trying to figure out the best solution to store and forward SQL data at a remote site. The current system setup looks like this.

Central site - Ignition Gateway with SQL bridge with transaction group pushing data to Azure SQL instance. Data is pushed once a minute based on trigger tag.

  • Site to Site VPN to remote site
  • Central gateway pulls data from 2 PLCs at remote site and pushes to Azure SQL
  • If site to site VPN goes down, data is lost

Remote site - Ignition Edge Panel and Sync Services (not configured yet, need to create project)

I need to be able to store and forward data from remote site to Azure SQL when site to site VPN goes down between central and remote site. I know this is possible with Edge Sync services for the central historian (currently Mariadb) but I need store and forward capability for the 1 minute SQL data to Azure.

One option appears to be buying the SQL bridge module for the remote site and setting up a gateway there just for this purpose. Then creating a transaction group for the remote site that pushes directly to Azure SQL. So if central/remote VPN connection goes down or Internet at remote site goes down the SQL data will store and forward.

Curious if anybody has run into a similar issue and what the solution was.

Thanks!

Yes, this can use that remote site's S&F system. Note, not available for Edge. Edge cannot talk to databases.
