Project Tree in Online Mode

When Automation Builder enters Online Mode internally, an identification message (like a “ping” command) is sent to all configured Communication Modules.

The connection’s status to a module is depending on the response to the identification message and displayed by a symbol in the device tree:

	Module responds to identification message and is available for online connection.
	Module responds to identification message, but some warning messages are available. See Error_Messages_Warnings_Notes for details Error Messages, Warnings and Notes in Online Mode.
	Module does not respond to identification message and is not available for online connection.

Note

The identification is done once when switching from Offline to Online mode.

If a Communication Module is a Master Unit, and it has several slave devices configured below his level (e.g. PROFIBUS®, CANopen®, PROFINET®), they will have always the same state as the Master, i.e. there is no identification check for the Slaves of a field bus.

Apart from the online availability the blue circle icon indicates also the possibility to activate a diagnosis view on the right screen part by a double-click on the tree node with the green circle.
