PART 1: CX-Programmer
CHAPTER 4 – Reference
Downloading Programs to the PLC
Programs can be downloaded to the PLC from the project when the PLC is in Program mode. If the PLC is not
already in this mode, CX-Programmer changes the mode automatically.
Use the following procedure to transfer a program to the PLC.
1, 2, 3...
The program is compiled and then a confirmation dialog is displayed. The Ladder program is out-out,
preventing any further editing. The operating mode and the cycle time of the task are displayed in the status bar.
It is not possible to download a single program or selection of programs to the PLC – all programs are
downloaded together. However, any programs that have 'unassigned' tasks (set in the program properties) will
not be included.
Programs can be downloaded to CS/CJ-series PLCs Ver. 2.0 or later or CP-series PLCs, and downloading by
task (program) instead of the whole user program is possible (CX-Programmer Ver. 4.0 or later). Select Partial
Transfer – Task Transfer to PLC from the PLC Menu, and download a specified single task or multiple tasks.
This function enhances the efficiency of program development by multiple personnel. Particularly, by
downloading to the PLC by task (program), only the parts to be changed are reflected in the PLC, resulting in
fewer working errors.
Note: When the CX-Programmer version 5.0 is used to download projects with a CS/CJ-series CPU Unit
with Ver. 3.0 or later or CP-series CPU Unit, I/O comments, symbol names, rung comments, and
other data can be transferred either to the Memory Card, EM file memory, or comment memory
(within CPU Unit's flash memory). Therefore, even if a Memory Card or EM file memory is not
available, the I/O comments, symbol names, rung comments, or other data can be stored in the CPU
Unit's comment memory.
Note: This functionality is not supported for CP1E CPU Units.
The following option will be displayed for a CJ2 CPU Unit: Clear automatic allocation area and forced status. If
this option is selected when downloading programs, all automatic allocation area data and forced status will be
cleared. Select this option when it is necessary to change the automatic allocation area.

3. Select the Transfer from PLC button from the toolbar. A warning dialog is displayed
indicating that
The Upload Options dialog is displayed allowing individual components to be selected for
transfer from the PLC, for example, programs, expansion functions (if available), memory
allocation, settings, IO table and memory.
Note: It is possible to upload a single program or section for online-editing, if section
markers have been included in the program. When a single section has been
uploaded, it can only be online-edited, or copied to another, complete program.
Note: It is possible to load symbol definitions from the PLC, if it has a file-card
(CS/CJ/CV PLCs), file memory or comment memory. Loading symbols from
comment memory is for backward compatibility with the OMRON SSS package:
the symbols contained in the memory will be unnamed, global symbols.
Note: When Start Auto Decompiling is checked CX-Programmer automatically starts to
decompile after uploading the program from the PLC.
4. Set the settings as required and select the OK pushbutton.
5. The Uploading dialog indicates the success (or not) of the transfer operation. Any errors
are written to the Error Log. Select the OK pushbutton to complete the operation.
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.
Select the Transfer To PLC button from the toolbar. The Download Options dialog is
displayed allowing the download of programs, settings and IO table individually or
together.
Note: It is possible to save symbol definitions to the PLC, if it has a file-card (CS/CJ/CV
PLCs), file memory or comment memory. Saving symbols to comment memory is
for backward compatibility with the OMRON SSS package: only global symbols
without names are downloaded.
3. Set the settings as required and select the OK pushbutton. The items that can be
downloaded vary according to PLC series.
