14: Tunnel and Modbus Settings
The xSenso 2100, xSenso 21A2 and xSenso 21R2 have two tunnels through which you may view statistics or configure the Accept Mode. The Modbus configuration page allows configuration of Modbus servers listening on the TCP ports.
Tunnel Settings
Tunneling parameters are configured using the Tunnel menu and submenus. The Tunnel settings allow you to configure how the Network tunneling operates.
Note: The following section describes the steps to view and configure Tunnel 1 settings; these steps apply to other tunnel instances of the device.
Accept Mode
In Accept Mode, the xSenso listens (waits) for incoming connections from the network. A remote node on the network initiates the connection.
The configurable local port is the port the remote device connects to for this connection.
