2. Select the Compare with PLC button from the toolbar. The Compare Options dialogue
is displayed.
3. Set the Programs field and select the OK pushbutton. The Compare dialogue is
displayed.
Details regarding comparisons between computer and PLC programs are displayed in the Compile tab of the
Output Window.
Offline Program Verification
Program verification is possible offline between the current project and a closed project file. (Select Compare
Program from the File menu and select the file to be compared.) 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 or omitted 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 saved in
the CSV file.
*: Mismatch, D: Difference, M: Moved, N: Missing
Monitoring a Program During Execution
Once the program has been downloaded, it can be monitored in the Diagram Workspace (which acts a mimic
display) during execution. When CX-Programmer goes on-line to a PLC, the
Toggle PLC Monitoring button
also toggles on and starts to monitor the program. If the program is not monitored, use the following procedure
to monitor the program.
1, 2, 3… 1. Select the PLC object in the project workspace.
2. Select the Toggle PLC Monitoring button from the toolbar.
3. As the program executes, data and power-flow can be followed in the Ladder program;
for example, connections are selected and values are incremented.
Note: Individual PLC data elements can be monitored via the Watch Window. This window allows
monitoring of addresses from multiple PLCs at the same time.
Note: The values are monitored in a format according to the data-type of the symbol which is being
used for the operand, or the data-type of the instruction operand itself. To always monitor in a
single, hexadecimal format, turn on the
Monitor In Hex option from the toolbar.
