1. After editing is completed, select Program - Online Edit - Send Changes.
The Send Changes Dialog Box will be displayed.
2. Select the desired transfer mode and click the OK Button. The edited ST
program will be transferred to the PLC.
For details on the transfer modes, refer to Transfer Modes on page 177 and
Selecting a Transfer Mode on page 177.
3. After the transfer is completed, the ST program will return to its previous
status in which the ST program cannot be edited. If further editing is nec-
essary, resume the online editing procedure from the beginning of the pro-
cedure (Starting Online Editing).
To discard the changes made to the ST program, select Program - Online
Edit - Cancel. The edited ST program will not be sent to the PLC, and the ST
program will revert to the original status before online editing was started.
In Standard Mode, both the ST program's source code and object code are
transferred to the CPU Unit. Some time may be required for Standard Mode
transfers because of the quantity of data that must be sent. Other editing or
transfer operations cannot be performed until the transfer has been com-
pleted.
In Quick Mode, only the ST program's object code is transferred to the CPU
Unit. The ST source code is not transferred, making Quick Mode faster than
Normal Mode. After transferring the object code in Quick Mode, either 1)
select Program - Transfer SFC/ST Source to PLC to transfer the source
code or 2) transfer the source code according to instructions displayed in a
dialog box when you go offline.
After transferring the object code, a yellow mark will be displayed at the bot-
tom of the window until offline status is entered to indicate that the source
code has not yet been transferred. This yellow mark will disappear when the
source code is transferred.
As a rule, use Standard Mode to transfer ST program changes, unless online
editing is performed frequently. If too much time is required, increase the baud
rate as much as possible before the transfer. If too much time is still required
and debugging efficiency is hindered by continuous online editing, use Quick
Mode as an exception, but be sure you understand the restrictions given in
the following note (Mode Restrictions in Quick Mode).
When the ST program's ST source code is not being transferred, the CX-Pro-
grammer cannot upload the program correctly the next time.
Consequently, after the ST program's online editing changes have been trans-
ferred in Quick Mode, it may be impossible to upload the program later (see
note) if the computer or CX-Programmer crashes before the source code can
be transferred.
Note It may be still be possible to transfer the source code with the following proce-
dure, even if the above problem occurs.
