2. Click on the associated Settings pushbutton in the Change PLC dialog.
3. In the Network tab, define the FINS Destination Address by entering the Network and
Node.
4. Set the Response Timeout(s) to adjust for a slow network as necessary.
5. Enter the Frame Length in the Frame Length field. Refer to Controller Link
documentation for further information.
6. In the Driver tab, set the appropriate setting for the Shared RAM Address, Interrupt Level
and Baud Rate fields. Refer to Controller Link documentation for further information.
7. Select an appropriate Node and Unit for the Network address.
8. Select the OK pushbutton to save the settings or select the Cancel pushbutton to abort the
operation.
Ethernet
Ethernet is a commonly used network capable of achieving a high rate of data transmission.
An NIC board must be installed inside the computer and TCP/IP protocols must be added and configured.
Use the following procedure to configure Ethernet.
1, 2, 3…
1. Ensure the Network Type is Ethernet.
2. Click on the associated Settings pushbutton in the Change PLC dialog.
3. In the Network tab define the FINS Source Address: Network field by entering the
Network Address.
4. Check the Network and Node addresses for the PLC and enter them in the FINS
Destination Address: Network field and Node field respectively.
5. Set the Response Timeout(s) to adjust for a slow network.
6. Enter the Frame Length in the Frame Length field.
7. In the Driver tab, check the Workstation Address and enter it in the Workstation: Node
Number field. Alternatively, select the Auto Detect setting to automatically determine the
workstation address.
8. Check the PLC IP address and enter it in the PLC: IP Address field.
9. Check the FINS UDP Port Number and enter it in the PLC: Port Number field.
10. Select the OK pushbutton to accept the settings. Select the Cancel pushbutton to abort the
operation.
Note: If using a subnet mask which is not 255.255.255.0 you will need to add the IP Address of the
PC wishing to connect, into the Ethernet unit. Do this using the I/O table.
Connecting Using EtherNet/IP
The CJ2 CPU Units support EtherNet/IP to enable high-speed and high-capacity data links between
PLCs through Ethernet cables. This section describes the two methods that can be used to connect a
PLC on a EtherNet/IP network.
♦ Directly connect to the gateway PLC using a USB cable, and connect to the PLC on the network through
the gateway PLC.
