Deleting Objects

Using the Mouse

Using the Keyboard

  1. Select the object to be deleted.

  2. Use the Edit > Delete menu command.

Deleting the selected object:

  1. Select the object to be deleted.

  2. Press the Del key.

Deleting the object left of the gray field:

  1. Press the Backspace key.

Result: The selected object is deleted. The actual parameters are deleted together with the object, even if they were not selected explicitly. Boolean links are only deleted if they are selected explicitly.

Cutting Objects

Using the Mouse

Using the Keyboard

  1. Select the object to be cut.

  2. Use the Edit > Cut menu command.

    or

    Use Cut from the context menu (right-click).

  1. Select the object to be cut.

  2. Press the Ctrl+X key combination.

Result: The selected object is cut from the section and copied to the clipboard. This is also the case for the actual parameters.

The cut object can be inserted in any other position (also in another LL984 network).

Copying Objects to the Clipboard

Using the Mouse

Using the Keyboard

  1. Select the object to be copied.

  2. Use the Edit > Copy menu command.

    or

    Use Copy from the context menu (right-click).

  1. Select the object to be copied.

  2. Press the Ctrl+C key combination.

Result: The selected object is copied to the clipboard. This is also the case for the actual parameters.

The cut object can be inserted in any other position (also in another LL984 network).

Pasting Objects from the Clipboard

Using the Mouse

Using the Keyboard

  1. Use the menu command Edit > Insert.

    or

    Use Paste from the context menu (right-click).

  2. Left-click the target position.

  1. Move the cursor to the target position pressing Ctrl and using the arrow keys.

  2. Press the Ctrl+V key combination.

  3. Press Enter.
NOTE: (for pasting contacts and coils) If the target position already contains a contact or coil, the existing object is overwritten by the new object.
NOTE: The following is the behavior of the Copy, Cut and Paste on a function block instance. It only applies to graphical languages as FBD, LD and LL984.

  • Using the Paste function after a Copy of an object:

    As a result of a Copy, a new function block instance (FBI name) is used. The Paste function creates a new FBI whenever it is repeated. Accordingly, the FBI name is incremented.

  • Using the Paste function after a Cut of an object:

    As a result of a Cut , the same instance of the function is used. The Paste function uses the same FBI whenever it is repeated. Accordingly, the FBI is identical.

NOTE: Using same instance of a function block is not recommended because it can lead to incorrect execution of the function blocks. A function block instance uses contextual variables that are owned by each instance usage and cannot be applied to any other. For instance, each current value is specific to one timer instance and one timer usage (Current value of a timer named TON_1 cannot be shared with another timer named TON_2).

Moving Objects

Using the Mouse

Using the Keyboard

  1. Select the object to be moved.

  2. Position the mouse pointer on the selected object. (On one of the selected objects if several are selected).

    Result: The mouse pointer changes its symbol to .

  3. Click the left mouse button and keep it pressed.

    Result: The mouse pointer changes its symbol to .

  4. Drag the object to the new position and release the mouse button.

  1. Position the gray field on the object to be moved.

  2. Press the Space bar .

  3. Press the Shift key and keep it pressed.

  4. Move the object to the target position using the arrow keys.

Result: The selected object is moved from its original position to the target position. The object's actual parameters are moved together with the object. Boolean links are only kept for horizontal movement operations.

NOTE: A moving of FFBs to cells that are already occupied (e.g. by contact, coil, other FFB, boolean link), is not possible.
NOTE: The move operation is also possible across sections between different opened LL984 networks.
NOTE: When objects are moved beyond the visible area of the editor window, automatic scrolling of the window will not begin until you reach the edge of the window with the mouse pointer, not as soon as the objects are moved beyond the edge.

Copying Objects via Drag-and-Drop

Using the Mouse

Using the Keyboard

  1. Select the object to be copied.

  2. Position the mouse pointer on the selected object.

    Result: The mouse pointer changes its symbol to .

  3. Click the left mouse button and keep it pressed.

  4. Press the Ctrl key and keep it pressed.

    Result: The mouse pointer changes its symbol to .

  5. Drag the object to the new position.

    NOTE: This is also possible across sections between different opened LL984 networks.

  6. Release the mouse button.

Result: A copy of the selected object is pasted at the target position. The object's actual parameters (variable/address) are copied together with the object. A new instance is automatically created for FFBs.
