Project Tree in Online Mode

When Automation_Builder enters the online mode internally, an identification message is sent to all configured Communication Modules.

The connection’s status can be recognized 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 and Notes (Dialogs).
	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 contains several configured slave devices below the level (e.g. PROFIBUS, CANOPEN, PROFINET) will always have the same master, i.e. there is no identification check for the slaves of the fieldbus.

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