Edit Function Block Diagram Logic in Program Mode

When opening a function block routine, it is displayed within the Function Block Editor routine window. This window appears within the main
Logix Designer
 application screen. It contains tabs for all open routines, a view for each routine, and a sheet toolbar to help work with the sheets within each routine.
To edit Function Block Diagram Logic in Program Mode
  1. Open the function block routine to change.
  2. From the
    Logic
     menu, choose
    Start Pending Routine Edits
    .
    The
    Pending Edits
     view is created, displaying an identical copy of the original routine. At this point, before making any edits, the blocks in the
    Pending Edit
     view reference the same block tags as the blocks in the Original view. The routines are identical.

    Pending Edits
    view.
    To view the original logic, select the
    Original View
     button on the sheet toolbar.

    To view the
    Original
     view and
    Pending Edits
     view at the same time, open a new window.
  4. When finished making changes to the routine and it verifies, select the
    Logic > Accept Pending Routine Edits
    .
    The new routine logic is transferred to the controller and replaces the original routine logic.
