1. Connecting Methods

Ethernet (Fins/UDP)
NB to CP1L-EM (2pcs) through Ethernet (FINS/UDP)

2. Wiring diagram

In order to avoid malfunctions caused by interferences, use shielded cables.

3. HMI Attribute settings

Start NB-designer, create a new program, drag and drop the NB (*TW001) and two Omron CP Series Ethernet (UDP Slave) on the “Project Structure Window”.

Double click on the NB in the “Project Structure Window” to open the HMI Attribute.
Select the ‘HMI’ tab and set the IP address to (192.168.250.1) and the Subnet Mask to (255.255.255.0).

4. PLC Attribute and PLC settings (PLC0)

Double click on the CP(PLC0) in the “Project Structure Window” to open the PLC Attribute. Set the IP address to (192.168.250.2), Port (9600) and the Node ID to (2) in the PLC tab.

Start CX-Programmer, create a new program and select a CP1L-EM. Open the Settings properties. Select the Build-in Ethernet tab.
Set the IP address to (192.168.250.2), Sub-net Mask to (255.255.255.0) and the FINS Node No. to (2).

5. PLC Attribute and PLC settings (PLC1)

In NB-Designer, double click on the CP(PLC1) in the “Project Structure Window” to open the PLC Attribute. Set the IP address to (192.168.250.3), Port (9600) and the Node ID to (3) in the PLC tab.

Start CX-Programmer, create a new program and select a CP1L-EM or add a second CP1L-EM to the existing file. Open the Settings properties. Select the Build-in Ethernet tab.
Set the IP address to (192.168.250.3), Sub-net Mask to (255.255.255.0) and the FINS Node No. to (3).

6. HMI and PLC Network settings

In NB-Designer double click on the NB in the “Project Structure Window” to open the HMI Attribute.
Select the ‘HMI’ tab and select ‘Network Device Settings’.

Add a Device, set Device Type to (HMI), Device No. (HMI0), IP Address (192.168.250.1), Port Num: (9600), Comm Protocol (OMRON CP Series Ethernet UDP) and Node ID to (1).

Add a Device, set Device Type to (PLC), Device No. (PLC0), IP Address (192.168.250.2), Port Num: (9600) and Node ID to (2).

Add a Device, set Device Type to (PLC), Device No. (PLC1), IP Address (192.168.250.3), Port Num: (9600) and Node ID to (3).

Save, compile and download the NB program and CX-Programmer settings to the units and restart all.

7. Example program

Attached file:

Example program for a NB7W-TW01B with two CP1L-EM(PLC0/PLC1) screens for Read/Write data to the CP1L’s through Ethernet (FINS/UDP) and a NB Setup screen to Adjust settings like Date, Time, Buzzer, Screen Saver, Brightness adjust and Calibrate screen.

For the CP1L-EM’s there is a CX-Programmer file for two PLC’s with the Communication settings for the Build-in Ethernet port.
