If all system requirements are fulfilled, ibaPDA displays the S7 TCP/UDP interface in the interface tree of the I/O Manager. ibaPDA-Request-S7-UDP is a module (S7 Request) of this interface.

If you select the data interface in the tree, you can see an overview of diagnostics information on the configured connections between ibaPDA and the controllers.

The interface has the following features and configuration options.

Port no.

<Reset port to default>

Use this button to reset the port to the default port number.

<Allow ports through firewall>

When installing ibaPDA, the default port numbers of the used protocols are automatically entered in the firewall. If you change the port number or enable the interface subsequently, you have to enable this port in the firewall with this button.
