You can also display the accessible devices and display and edit the properties of an interface using the shortcut menu.

The following figure shows the "Online access" folder in the project tree:

①	"Online access" folder in the project tree All interfaces installed in the programming device/PC are displayed in the "Online access" folder.
②	Show/hide interfaces Use the function "Show/hide interfaces" to show or hide individual interfaces.
③	Status display for the interfaces The current status of an interface is indicated by an icon to the right of the name. You can see the meaning of the icon in the tooltip.
④	Updating the list of accessible devices. This function is available for each hardware interface of the programming device/PC. Software interfaces, such as a remote connection, do not offer this function.
⑤	Display more information This function is available for each hardware interface of the programming device/PC after you have executed the function "Update accessible devices". You can find additional information in the detailed view of the overview window.
⑥	Devices connected via the respective interface with the programming device/PC The type of the device and its status are displayed by the preceding icon.

The accessible devices are identified with an icon according to their type and status. The following is an overview of all icons and their meaning.

	Icon for unidentified modules This icon is displayed whenever the identification of a module is not yet complete or when the identification of a module was not successful, for example, because the required online data could not be read.
	Icon for the following device types: PLCs SIMOCODE pro devices IE/PB links CPs of PC systems SCALANCE head modules S7-300 and S7-400 CPs PROFINET IO devices and PROFINET CPs SCALANCE modules and gateways that could not be identified
	PROFINET IO devices, encoders, switchgear, sensors and identification systems that were replaced by similar devices because these could not be identified
	Icon for the following device types: HMI devices PROFINET IO devices of the HMI type if these could not be identified and were therefore replaced by a similar device
	PROFINET IO devices of the drive type that could not be identified and were therefore replaced by a similar device
	PROFINET IO devices of the type development kit and network components that could not be identified and were therefore replaced by a similar device
	PROFINET IO devices of the type TeleService adapter that could not be identified and were therefore replaced by a similar device
