CJ2 CPU Unit Hardware User’s Manual
Using commercially available RS-232C cable, connect the CX-One Support Software (e.g., CX-Pro-
grammer) via a standard serial port at the personal computer.
The network type must be set to the Toolbus. A Host Link connection cannot be used.
Additional Information
Connecting to the PLC by EtherNet/IP via USB or RS-232C
The Support Software can be directly connected by USB or RS-232C to one CJ2 CPU Unit and
access other CPU Units on the EtherNet/IP network via the built-in EtherNet/IP ports on the CJ2
CPU Units. For details, refer to the CJ2 CPU Unit Software User’s Manual (Cat. No. W473).
Use the following cable to connect the CJ2 CPU Unit to the computer running the Support Software.
*1 Connection is not possible from CX-One Support Software using the SYSMAC WAY (Host Link) protocol.
