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.
The on-line edit can be cancelled at any point prior to committing the changes by selecting the
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.
Uploading Program/s from the PLC
A program can be uploaded from the currently connected PLC into the open project. All associated program
data (for example symbol details and IO table) are uploaded.
Use the following procedure to transfer a program from the PLC.
1, 2, 3…
1. Select the PLC object in the project workspace.
2. Select
the
Work On-line
button from the toolbar. A confirmation message is displayed;
select the
Yes
pushbutton to connect to the PLC.
