Interface selection and operation

All configuration operations are made to the interface selected in the Interface field.

The status of the selected interface service is indicated in the task bar along the bottom of the PI ICU main dialog box. An asterisk (*) appears in the PI ICU title bar when unsaved changes exist for the currently-selected interface.

• Click Apply to save changes and keep the PI ICU application active, or choose Interface > Save.

• Click Close to save any outstanding changes to the currently selected interface and exit the PI ICU application.

  Note: Saved configuration changes are not applied to running interfaces. For a change to take effect, the interface must be stopped and restarted.

The interface definition area contains the following settings:

• Interface

  The Interface drop-down list indicates the currently selected PI interface. Any new interfaces added to PI ICU (using New Windows Interface Instance from EXE and New Windows Interface Instance from BAT File operations) are included in the drop-down list.

  Only one interface can be selected for configuration at any given time. If - select - appears in the Interface drop-down list, no interface has yet been selected.

• Rename

  Click Rename to specify a different display name for the interface, as the interface is listed in the Interface drop-down list. If a new name is specified, then the interfaces are reloaded.

• Type

  The Type menu specifies the type of interface being configured and provides a list of supported interface types. In most cases the PI ICU is able to determine the interface type automatically. If the PI ICU is not able to determine the interface type, you must select the proper interface type to access a matching PI ICU control.

  Once the correct interface type is selected, a PI ICU control installed for the interface type becomes available under the Interface page. The full name of the interface type is displayed to the right.

  Note: Be sure that the Type field is properly set when registering an interface in PI ICU.

• Description

  The description field is an optional text field for the user to document/identify the specified interface.
