1. Connecting Methods
Ethernet (Fins/UDP)
NB with a CP1L-EM and a CJ2M-CPU33 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 one Omron CP Series Ethernet (UDP Slave) and one Omron CJ 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 CJ(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 CJ2M-CPU33 or add a CJ2M-CPU33 to the existing file. Open the IO Table and Unit Setup. Select the Build-in Port/Inner Board and double click on the CJ2M-EIP (Built In Ethernet/IP Port for CJ2M).
Select the TCP/IP tab and set the IP address to (192.168.250.3), Sub-net Mask to (255.255.255.0) and the FINS Node No. to (3).
Set the ‘Rotary’ Node Address Setting Switch at the front of the CJ2M-CPU33 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 second Master Device, set Device Type to (HMI), Device No. (HMI0), IP Address (192.168.250.1), Port Num: (9600), Comm Protocol (OMRON CJ Series Ethernet UDP) and Node ID to (1).
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 one CP1L-EM(PLC0) and one CJ2M-CPU33(PLC1) screen for Read/Write data to the CP1L/CJ2M 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 and the CJ2M-CPU33 there is a CX-Programmer file for both PLC’s with the Communication settings for the Build-in Ethernet port.
