I/O Interface configuration is performed on a Driver's configuration dialog box. To access the configuration of this dialog box in E3 (version 1.0), follow these steps:

1.Right-click a Driver object (IODriver).

2.Select the Properties item on the contextual menu.

3.Select the Driver tab.

4.Click Other parameters.

In E3 version 2.0 or later, click Configure driver on a Driver's toolbar. In Elipse SCADA, follow these steps:

1.Open the Organizer.

2.Select a Driver on Organizer's tree.

3.Click Extras on the Driver tab.

Currently, an I/O Interface allows opening only one connection for each Driver. This means that, if users want to access two serial ports, they must add two Drivers to an application and then configure each Driver for each serial port.
