tunnel-SerialTunnel
This component is the server-side component used to support tunneling of Windows serial-connected PC applications to devices
reachable in a station’s driver network. Typically, serial tunneling is used with a legacy vendor-specific PC program to access
RS-232–connected devices attached to a controller.
You can add one or more SerialTunnels under a station’s TunnelService. Each SerialTunnel associates with one specific driver network (and corresponding controller serial port).
Figure 85. SerialTunnel properties
In addition to the standard property, Status, these properties are unique to this component.
| Name | Value | Description |
|---|---|---|
| Enabled | true (default) or false |
Turns serial tunneling on (true) and off (false).
|
| Connections | read-only | Indicates the number of tunnel connections, as either 0 (none) or 1 (maximum). |
| Identifier | read-only | Reports the entered Port Name slot in the Serial Port Config container (below) used as the tunnel name when configuring the client-side Serial Tunneling window.
|
| Serial Port Config (container) | additional properties | Holds configuration properties for the controller serial port as used by the specific driver network. Refer to the separate topic, serial-SerialHelper for property descriptions. |
Actions
- Disconnect All disconnects any active connection through this SerialTunnel (maximum of 1). This removes the TunnelConnection below it. The remote (serial tunnel client) side displays a popup message: Connection closed by remote host.NOTE: Any TunnelConnection component also has its own Disconnect action, which effectively performs the same function.
