possible from the built-in EtherNet/IP port or an EtherNet/IP Unit port if the
network connection is set for EtherNet/IP. Always set Ethernet or Ethernet
(FINS/TCP) to connect to an Ethernet network. In addition, connection is
impossible when “USB” is selected in the network settings. Select “Toolbus
(USB port)”.
Note 2: CJ2 CPU Unit cannot select this network type.
Note 3: When connecting online with a SYSMAC CS1 Board, specify one of the device
types in parentheses.
CS1 Board can be selected as the network type only
when one of these device types is selected.
Click the
Settings Button to display the Network Settings Dialog Box for each type of
network. Details are described here for Toolbus, SYSMAC WAY, and Ethernet. Refer to
the
CX-Programmer Operation Manual (Cat. No. W446) for other methods.

Click the Driver Tab and set the following settings as required.
Port Name: Select the computer’s COM port from the drop-down list.
Baud Rate: Select the baud rate (bits/s) from the drop-down list.
Baud Rate Auto-Detect: Clear this selection to connect with the baud rate set on the
computer, ignoring the baud rate of the serial port on the CPU
Unit. To disable automatic detection of the baud rate, the DIP
switch on the CPU Unit must be set as follows:
For peripheral port connection: Pin 4 of the DIP switch must
be OFF (automatic detection of communications settings: use
Programming Console or CX-Integrator settings).
For RS-232C port connection: Pin 5 of the DIP switch must be
ON (automatic detection of communications settings: use
CX-Integrator settings).
Note For automatic baud rate detection with the Toolbus protocol, the baud rate setting on
the computer is used and the serial port on the CPU Unit is set to the same value.
For automatic online connections, the communications settings (device type, serial
communications mode, baud rate, and other communications settings) of the serial
port on the CPU Unit are detected and the device type information on the computer
are set to the same values.
