1) When uploading programs from a C-series PLC or other CPU Unit that cannot record rung comments.
2) When uploading programs from a CS/CJ/CP-series, CVM1/CV-series, or C200HX/HG/HE-ZE CPU Unit.
When the uploaded programs are changed in the actual CPU Unit using functions such as online editing, the
position of the rung comment can be edited.
Downloading/Uploading
CX-Programmer can also use a PLC instruction to store the section markers in the PLC when the program is
downloaded. This will allow CX-Programmer to upload a single section for online-editing. It will also allow
CX-Programmer to upload the program complete with section breaks.
A single program section may be uploaded for online-editing (reducing the transfer time to a minimum).
However, it may not be downloaded since it is only a program segment. To download a program section, it is
necessary to copy it into a complete program.
Cross-Reference Report
The Cross-Reference Report allows the symbol usage within different memory areas to be examined. It can be
used for checking the values being set by instructions when the program is not behaving as expected. It can also
allow the programmer to make efficient use of memory resources.
Use the following procedure to generate a cross-reference report.
1, 2, 3…
1. Select
the
Cross-Reference Report
button from the toolbar to open the Cross-Reference
Report.
2. Select a usage from the
Report type
field; either
Detailed Usage
,
Usage Overview
,
Usage
Overview with comments
,
Usage Overview Including Unused, Usage with Comments
Including Unused
, or
Duplicate Usage Over Programs
.
3. Select an area from the
Memory Area
field. When changing options, reselect from the
Memory Area
field to refresh the report.
4. Select
the
Generate
pushbutton to activate the report. In addition to the address report
information, the amount of free program memory in the PLC is displayed in the
Free UM
field. The total program memory size of the PLC is displayed in the
Total UM
field.
The
Detailed Usage
option within the
Report type
field displays information about the usage of any address
used within the PLC program(s). The program name, step number, instruction type, the start address of the
operand and symbol details relating to each usage are shown.
The
Usage Overview
option within the
Report type
field displays an overall summary of the usage for the
selected memory area, showing only the addresses that are in use. For each used address, a usage count is
displayed. The ‘D’ symbol denotes that the address has a symbol assigned to it.
The
Usage Overview Including Unused
option within the
Report type
field displays the usage overview of the
memory area, including addresses that are not used.
The cross reference function usage list can be displayed with I/O comments and the list can also be printed (CX-
Programmer Ver. 4.0 or later). Therefore, the user can check what the addresses mean when checking the
number of times the addresses have been used. This reduces the labor required for programming/debugging.
This function can also be used to jump to the position of the rungs being used.
