Use the following procedure to compare programs on the computer and on 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.
3. Select the Compare with PLC button from the toolbar. The Compare Options dialogue
is displayed allowing comparisons of programs, settings and IO table individually or
together.
4. Set the settings as required and select the OK pushbutton. The items that can be
downloaded vary according to PLC series.
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 colour.
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.
1, 2, 3… 1. Select the PLC object in the project workspace.
2. Select the Transfer/To File or Transfer/From File options from the PLC menu. Or
select Load Comment/Program or Save Comment/Program options from the File
menu. A dialogue is presented which allows the filename/s to be set or browsed. Choose
whether to include
Programs , Comments , Symbols or Index in the transfer on this
dialogue.
For programs, a short
Comment may also be given for inclusion in the file.
Note: When loading comments, text within the program comments (for the project’s PLC) are
overwritten. When loading symbols, the local and global symbols for the PLC and programs
are first emptied.
If the file-card cannot be attached directly to the computer
When the file-card cannot be attached to the computer, it is possible to transfer comments and symbols to the
PLC file-card directly using the Transfer to PLC option above. To write the program to the file-card, use the
above steps to produce the program file on one of the computer’s disks. It is then possible to transfer the file
between the disk drive and the file-card on a PLC using the CX-Server memory-card component – please refer
to the CX-Server PLC Tools user-manual.
