Canceling the Program Transfer
While transferring a program to or from a PLC it is possible to cancel the transfer by clicking the Cancel button.
However depending on when the button is pressed different functionality will occur.
If the Cancel button is pressed before or during the Memory Clear phase the memory clear will be completed
but the data transfer will not take place. If the button is pressed during the Transfer phase the transfer will be
stopped and the PLC memory will be cleared. The transfer will not be completed.
Comparing Programs
The project PLC program data can be compared with the data inside the PLC.
The following comparisons may be performed, depending on PLC type:
♦ Program step number and instructions;
♦ PLC data;
♦ Expansion Instruction Table (CQM1, C200HE, C200HG, C200HS and C200HX only);
♦ UM allocation data (CQM1, C200HE, C200HG, C200HS and C200HX only).
Use the following procedure to compare programs on the computer and on the PLC.
1, 2, 3...
Details regarding comparisons between computer and PLC programs are displayed in the Compare Result dialog
box.
The results of verification can be saved to a file in CSV format.
Two methods can be used to display the comparison results.
• Overview display: Program lists are displayed of the compare programs.
• Mnemonic display: The specified program is displayed in mnemonic form with differences displayed in color.
The comparison results are displayed by section and mnemonic, including added instructions. You can also
jump from the mnemonic comparison results to the corresponding position in ladder view. The comparison
results can be saved in a file by selecting Save As from the File menu in the Compare Result dialog box. If the
file is saved from the overview display, the comparison results for all programs will be saved in CSV format. If
the file is saved from the mnemonic display, the comparison results for the currently displayed program will be
saved in CSV format.
The following abbreviations will be displayed between program addresses and mnemonics and will be in the
CSV file.
*: Mismatch, D: Difference, M: Moved, N: Missing
Transferring Programs, Symbols, Comments and Index to and from File/File-card
It is possible to write a combination of program code, program comments and symbol definitions to a set of
files. It is possible to read these files back.
If a file-card can be attached directly to the computer (via a PCMCIA controller, for example), then it can be
used as a disk device like a floppy drive, and files may be directly transferred with it.
