4-2-3 Connecting to Ethernet (CJ2H-CPU6@-
EIP and CJ2M-CPU3@ Only)
With the CJ2H-CPU6@-EIP or CJ2M-CPU3@, use a commercially available Ethernet 100Base-TX STP
twisted-pair cable (straight) to connect the CX-One Support Software (e.g., CX-Programmer) to the
built-in EtherNet/IP port through the Ethernet switch. With the CJ2H-CPU6@-EIP, Ethernet twisted-pair
cable can also be used to connect to a personal computer. The same type of connection can be made
with the CJ2H-CPU6@ or CJ2M-CPU1@ through an EtherNet/IP Unit.
Use the following cable to connect the CJ2 CPU Unit to the computer running the Support Software.
*1 Use 100Base-TX when using tag data links.
*2 The following table shows the devices recommended for use with the built-in EtherNet/IP port.
