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… 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.
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.
