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

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.
