tunnel-TunnelService

Station server for “application tunneling,” where remote PCs with a NiagaraAX Tunnel Client installed can use a legacy or vendor-specific PC application to access devices connected to one or more driver networks. A tunnel connection allows the remote client application to operate as it were directly attached to the driver network (via a “virtual” PC port).

A client PC tunnels using an IP (LAN/WAN) connection, which is granted only after authentication as a station user (with admin write permissions for the particular child tunnel component accessed).

Currently, the following types of child tunnels are supported:

In any station, only one TunnelService is recommended. It can hold the required number of child tunnels, as needed.

The TunnelService contains the following properties:

Enabled

Boolean that must be true to support any tunnel server operations.
Server Port

Software port monitored for incoming client tunnel connections. Default port is 9973.
Status

TunnelService status, which should be ok (no special licensing required).
Connections

Number of active tunnel connections, which ranges from 0 (no active) to the number of child tunnel components.
