Viewing reachable stations

For a Supervisor station to successfully index all reachable stations in its NiagaraNetwork, it needs to know about their existence. The Supervisor station creates a routing table of stations to target them for indexing and resolve virtuals to them by using nspace ORDs.

Prerequisites:

You are connected to a Supervisor station that is properly licensed.
You have upgraded any direct (mid-tier) subordinate stations and other downstream mid-tier stations that you wish to participate to Niagara 4.13.
You have active downstream connections (via the NiagaraNetwork) with Niagara virtuals enabled with access control properly configured along all routes.
The edge-most stations can run Niagara versions

Reachable stations do not appear in the Reachable Stations container under the Sys Def device ext of the NiagaraStations of the Supervisor's NiagaraNetwork unless one or more of the following conditions apply.

NOTE: The second two conditions outlined below are not a common practice and are likely to only be executed when you diagnose reachable station problems. The first condition is the most likely practice, which would cause reachable stations to appear.

The Global Niagara Network Indexer was executed with Include Reachable Stations set to true, which forces an update of all reachable stations under the covers (see Configuring global system indexing to include reachable stations). This is the most common way reachable stations get populated in their containers, which may result in you not having to navigate to the individual reachable station containers.
You have run the remote spy for finding reachable stations (see Viewing reachable stations using Spy Remote)
You have manually invoked the Update Reachable Stations action on this container previously.

The Reachable Stations container component is available on the level of each NiagaraStation for security reasons. For example, if you have already set up permissions or roles per NiagaraStation, the stations’ Reachable Stations container inherits those settings.

Perform the following steps:

To identify all reachable stations in your Supervisor’s NiagaraNetwork, expand Config > Drivers > NiagaraNetwork > NiagaraStation > SysDef.
Right-click Reachable Stations and select Actions > Update Reachable Stations.
On the Update Reachable Stations window, click Yes.
From the drop-down menu, you can choose one of the two following options and click OK:
- If you have already found stations and you want to add only the newly discovered ones, select Only append new reachable stations.
- If you want to remove the stations that are already found and rebuild all reachable stations, select Clear and Rebuild All Reachable Stations.
In this example, as long as the connections along the route are operational at the time of invocation, the Supervisor finds reachable stations accessible through "Controller_817", which is "Controller_815" and adds it to the Reachable Stations property sheet.
