Going to instance or variable (without instance context)

How to go from Instances view to an →instance or a →variable (without →instance context):

If the instance or variable is included within a collapsed level, expand this collapsed level.
Open the context menu for the instance or variable and select Open Type. Alternative 1: Hold the Alt-key while double-clicking the instance/variable. Alternative 2: Select the instance/variable and press Ctrl+T.
Result: The editor is opened for the instance or the variable.
Alternative in order to open the editor in which the instance is used: Open the context menu for the instance and select Open Variable Declaration (Type) or press Ctrl+Shift+T.
Example: If the instance MyFB1 is declared/used within Program1, the command Open Instance for the instance MyFB1 opens the editor for MyFB1, while the command Open Variable Declaration (Type) opens the editor for Program1. If possible, the declaration within the editor is selected to easily spot it.

It is possible to quickly go from the declaration to appropriate elements within the editor:

If you want to go from the declaration of an instance to the appropriate type, use command Open Declaration within the editor. See "Opening declaration of an element" for ST-editor or "Going to the declaration of a block or variable" for FBD-editor.
If you want to go from the declaration of a variable to the usages, use command Find References within the editor. See "Finding references for element" for ST-editor or "Finding references (= usages) for an element" for FBD-editor.

Good to know
See "Going to a function block or program and setting the instance context", if you want to open the editor with instance context. Usually, an FBD-editor without instance context is used for editing while an FBD-editor with instance context is used for debugging. The default behavior of Neuron Power Engineer is that 2 different tabs can be opened for editing and debugging at the same time. Depending on your Neuron Power Engineer configuration, it is possible that Neuron Power Engineer opens just one tab for editing or debugging POUs in the FBD-editor. If you are interested in this behavior, ask the system integrator to activate the configuration variable `-Dlc3.fbd.autoswitch_edit_diagnostic_view`. This possibility helps to avoid any synchronization issues between editing and debugging tabs. But mind that the closing and opening of the tabs might change the tab order. As a consequence of the configuration variable, instead of opening 2 different tabs for debugging/editing, Neuron Power Engineer automatically closes a tab that might already be opened for the same POU but with the other purpose of editing/debugging. If there are any unsaved changes, you will be able to decide whether to save or discard the changes prior to closing the tab.
