Online Editing
Section 5-1
106
3 When the transfer is complete, the SFC program automatically reverts to the
non-editable state. To perform further editing, repeat the online editing procedure
from the beginning.
Transfer Modes
Standard Mode
The SFC source code and object code for the SFC program are both transferred to the
PLC (CPU Unit).
In “Standard Mode”, transfer may take a little longer to complete, depending on the
amount of data. You cannot perform another edit or transfer operation while a transfer
is in progress.
Quick Mode
Only the object code for the SFC program is transferred to the PLC (CPU Unit). The
SFC source code will not be transferred.
Since only the object codes are transferred, “Quick Mode” transfers are much faster
than “Standard Mode” transfers.
After transferring the object codes in "Quick Mode", transfer the SFC source code for
the SFC program to the PLC (CPU Unit) when, 1) executing "Transfer SFC Source to
PLC" or 2) going offline. After sending changes, a yellow mark will be displayed at the
bottom of the screen to indicate that “the SFC source code has not been transferred”.
The yellow mark will disappear after the SFC source code has been transferred.
Selecting a Transfer Mode
In general, unless online editing is done frequently and continuously, "Standard Mode”
should be used. If the transfer takes a long time to complete, try to resolve the situation
by increasing the connection speed with the PLC.
Should the transfer time take so long as to interfere with debugging (i.e. when
performing frequent and successive online edits while debugging), use “Quick Mode”
to transfer, but be fully aware of the “Limitations of Quick Mode (No SFC Source Code
Transfer)”, described below.
Caution
Limitations of Quick Mode (No SFC Source Code Transfer):
CX-Programmer is not capable of uploading a correct program, including the SFC
charts, unless the SFC source code for the SFC program has been transferred.
Hence, when working online, if changes made to the SFC program have been
transferred in "Quick Mode”, CX-Programmer may become incapable of uploading
the program if, before switching to the offline state (i.e. before the SFC source code
is transferred), the computer (CX-Programmer) crashes or if the PLC system
experiences a power failure.
Should such a situation occur, you may be able to re-transfer the SFC source code by
using the following procedure.
