Hi all,

I am in the process of working with the some tags in [System]Gateway/Gateway Network on a 8.1.32 system.

My question is, what's the difference between \_0:0:'Gateway', \_0:1:'Gateway' and \_0:2:'Gateway'. I noticed that the \_0:0: doesn't seem to have a value for Last Comm but the \_0:1: and \_0:2: ave values.

Any clarifications would be greatly appreciated.

That nomenclature indicates whether a gateway is independent, a redundant master, or a redundant backup. [Docs reference](https://docs.inductiveautomation.com/docs/8.1/platform/tags/types-of-tags/system-tags#gateway-network-system-tags):

> - Independent Gateways: 0:0
> - Redundant Master Gateway: 0:1
> - Redundant Backup Gateway: 0:2
> - "Virtual" route aliased to either the Master or Backup Gateways: 0:0

If you rename a gateway, remove a connection, or change the gateway redundancy, it might leave a stale tag/folder. E.g. connect an independent gateway (\_0:0) then change it to be a redundant (\_0:1/\_0:2).

From an old testing environment (note the lack of tags in the bottom 3):

Awesome, I must have missed that in the Docs. That's what I had in mind but wanted clarification. Thank you for the response, much appreciated.
