Once normal editing is completed, select the Send On-line Edit Changes button from the
toolbar. The changes are committed to the PLC. If the changes are successful, the edited area
of the Ladder program returns to read-only mode.

Cancel On-line Edit Changes button from the toolbar. The program is restored to prior to
starting on-line editing.
Select Go to on-line edit rung to go to the top of the on-line editing rung.
Working on rungs while the PLC is connected, and being able to easily change the program is one of the
quickest ways to complete and check a project. With the PLC running in Monitor mode it is possible to make
changes as if the PLC were not connected. The difference is that once a rung has been completed, it can be
downloaded to the PLC while the program is running.
When performing on-line editing, all rungs must be complete and valid before they can be transferred, whereas
in offline editing, an invalid rung and program can be saved at any time.
After forced setting/resetting of a bit online, a dialog box is displayed when status returns to offline to allow the
forced set/reset status of addresses to be displayed (CX-Programmer Ver. 4.0 or later). The forced set/reset
status can also be cancelled. Enable this function by selecting
Tools

Options and Check forced status after
online connection in the PLCs Tab Page (the default setting is OFF: no confirmation). This function prevents
going offline unprepared when the CPU Unit is still in forced set/reset status.
