Updating existing calls for changed interfaces

When opening the FBD-editor, the →calls of →blocks are automatically updated (also known as a quick fix) in the following cases, if the interface for blocks has been changed in the interface editor:

• An alternative name has been defined for the block.

• The display of the in-/outputs have been changed: Now the names are either displayed or not.

• If there is sufficient space in the drawing field for the changed call:

  • An in-/output is located on a different position/orientation than it is displayed in the call for name.

  • A new in-/output exists but is not displayed in the call.

Good to know

The automatic update is not provided in all variants of Neuron Power Engineer. So this feature is not available when creating safety-relevant applications (see "More features for safety-relevant applications"). In this case, update the changed interface yourself by selecting the call and pressing Ctrl+1 or the F5-key.   For the updating procedure, Neuron Power Engineer assists you as follows: Undo and redo the automatic update so that you are able to identify which calls have been updated. If there is not sufficient space in the drawing field for the changed call, best practice is to move the call highlighted with a warning so that there is sufficient space. Then select the call and press Ctrl+1 or the F5-key to update the call. If you prefer to use a context menu command instead of the keyboard shortcuts, select the call, open the context menu of the FBD-editor and select the command Update.

The calls of blocks are not automatically updated in case of the following interface changes:

• Only the interface has been resized. Solution: Resize the call directly within the drawing field. If this is not possible, best practice is to delete the call and to create a new call in the drawing field (e.g. by dragging from the project explorer).

• The display of the instance name has been changed. Solution: Show or hide the instance name directly within the drawing field.

• Existing in-/outputs have been deleted (details: see "Deleting FBD-elements or already declared variables"). Solution: Delete the faulty lines that are connected with a deleted in-/output. Then select the faulty block call and press Ctrl+1 or the F5-key to update the call.

• An existing in-/output has been deleted. Afterwards the name of the input has been used for creating a new output (or vice versa). Example: The input Pulse has been deleted and then the output Pulse has been created. Solution: Delete all lines that are connected with this in-/output. Then select the faulty block call and press Ctrl+1 or the F5-key to update the call.

• A value field within the interface has been added or deleted. Solution: Replace the existing call by a newly inserted call.

• A named value has been entered in the value field within the interface. But this named value does not exist in the declaration of the named data type anymore. Solution: Correct the content of the value field within the call so that the value field contains an existing named value. If this is not possible, replace the existing call by a newly inserted call or enter a literal within the value field.

 It is also possible to replace the call by a call of a different block (see "Replacing the call of a block").
