Note:
PLC Error Simulator
During simulation of ladder programs with CX-Programmer Ver. 7.2 or higher (CX-One version 2.1 or higher),
fatal and non-fatal PLC errors can be generated in a special window to debug ladder program sections that detect
errors.
The error-processing programs can be debugged easily in a separate window.
1. Connect the simulator online in the CX-Programmer, or start the integrated simulation.
2. If the CX-Programmer is used, select Simulation – PLC Error Simulator to start the PLC error simulator
program.
3. The PLC Error Simulator Window will be displayed. Select the errors that you want to generate, and press
the General Error Button or Clear Error Button to change the status.

Working On-line

Auto Online to a PLC
When maintaining a PLC, CX-Programmer can start monitoring the program of the connected PLC with a
toolbar button, after CX-Programmer is started. A PC must be connected to a PLC.
Use the following procedure to go on-line to the PLC automatically.
1, 2, 3...
Note: When the Auto Online connection is executed using CX-Programmer Ver.7.2 (CX-One Ver.2.1) or
higher, the available personal computer serial ports are automatically detected (automatic detection
of computer serial ports function). If a serial port than can be connected online is found, the
automatic connection is made from that serial port.
Auto Online - EtherNet/IP Node Online
You can automatically and easily connect online to a PLC when using CJ2 CPU Units connected to nodes on an
EtherNet/IP network.
Connection Types
♦ Connecting to the Target PLC When Connected to a PLC through a USB Cable
♦ Connecting to the Target PLC through an Ethernet Port on a Computer
Note: When running the CX-Programmer on Windows XP (SP2 or higher), Windows Vista, or Windows
7 and connecting online to a PLC via EtherNet/IP for the first time, the settings of the Windows
Firewall will need to be changed. Refer to Appendix B EtherNet/IP Connections from Windows XP
(SP2 or Higher), Windows Vista, or Windows 7 in Part 1: CX-Programmer for details on making
the changes.
The PLC-PT Simulation can also be started from the CX-Designer. Refer to the CX-Designer
Operation Manual (Cat. No. V099) for details on starting the simulation program from the
CX-Designer.
This functionality is not supported for CP1E CPU Units.
When the simulator program is stopped, the errors generated up to that point will be cleared.
CX-Programmer permits the connection of the PLC to the computer through the project, and
subsequent additional features once the PLC is on-line. Select the Work On-line button from
the toolbar to connect to the PLC.
1. Select the Auto Online button from the toolbar. A dialog is displayed showing the PLC
type and the network settings of the connected PLC, which CX-Programmer is searching.
When CX-Programmer successfully finds the PLC information, it automatically goes on-
line and transfers all the data from the PLC, for example, programs, expansion function
(if available), PLC settings, IO table (if available), symbol tables and comments.
2. Select the Select Serial Port option from the PLC Auto Online menu to change the serial
port when Auto Online. The default serial port is set to COM1.
