Creating a tag in ignition edge to reference a tag on another gateway

Ignition
1

I am working at a site where we have two ignition servers: 1 sitewide ignition gateway that monitors the entire plant, and 1 ignition edge server for a side building.

Both gateways are networked together via the gateway network and the Main ignition server has a remote tag provider so that we can grab tags from the edge server.

The problem we are running into is there are 4 tags that are on the main ignition server, that we would like to reference in the ignition edge server. We can easily create reference tags in the main ignition server that are referencing edge tags, but we cannot seem to make edge tags that are referencing the main ignition tags.

Is it possible to make reference tags in the edge server that reference the main server tags?

Right now the only way we've been able to do so it through the remote tag provider (which can not be created in edge). If it is possible what additional structures would i need to set up.

Thank you

You could create 4 memory tags in the Edge server, which would be visible to the Central server via the RTP.

In the Central Gateway, put tag change event scripts on each of the 4 tags, or a gateway tag change script watching all 4, and write the values to the remote tags when they change.

That was clever, worked great, thank you!
