1. Connecting Methods

Host Link (RS422)
NB with CP1L (2pcs) through COM2/RS422 (Host Link)

Start NB-designer, create a new program, drag and drop the NB and the two CP1L's on the “Project Structure Window”. Connect with the Serial connection line the CP1L's to the COM2 port of the NB.

(Default cable: NB-RSEXT-2M)

In order to avoid malfunctions caused by interferences, shield the cables properly.

3. HMI Attribute settings

Double click on the NB in the “Project Structure Window” to open the HMI Attribute.
Select the ‘COM2 Settings’ tab and set the Host Link Communication settings to Type (RS422), Baud Rate (115200), Data Bit (7), Parity Check (Even) and Stop Bit to (2).

4. PLC Attribute and PLC settings (PLC0)

Double click on the CP1(PLC0) in the “Project Structure Window” to open the PLC Attribute.
Set the Station No. to (0) in the PLC tab.

Start CX-Programmer, create a new program and select a CP1L. Open the Settings properties. Select the Serial Port 1 or Port 2 tab where CP1W-CIF11/12 is mounted.
Set the communication Settings to Custom, Baud (115200), Format (7,2,E), Mode (Host Link) and Unit Number to (0).

5. PLC Attribute and PLC settings (PLC1)

In NB-Designer, double click on the CP1(PLC1) in the “Project Structure Window” to open the PLC Attribute.
Set the Station No. to (1) in the PLC tab.

Start CX-Programmer, create a new program and select a CP1L or add a second CP1L to the existing file. Open the Settings properties. Select the Serial Port 1 or Port 2 tab where CP1W-CIF11/12 is mounted.
Set the communication Settings to Custom, Baud (115200), Format (7,2,E), Mode (Host Link) and Unit Number to (1).

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

6. Example program

Attached file:

Example program for a NB7W-TW00B with two CP1L(PLC0/PLC1) screens for Read/Write data to the CP1L’s through Host Link (RS422) and a NB Setup screen to Adjust settings like Date, Time, Buzzer, Screen Saver, Brightness adjust and Calibrate screen.

For the CP1L-M’s there is a CX-Programmer file for two PLC’s with the Communication settings for Serial Port 1.
