Omron HMI Communication With Keyence FA-M3 Series PLC

NV Range of HMI by Omron is capable of communicating with a wide range of PLC. As we already discussed the NV HMI Communication Cable for Panasonic PLC ,Omron HMI Cable Diagram for Allen Bradley PLC , Omron NV HMI Connection with Siemens PLC. Today we will see the step by step procedure for NV HMI Communication with Keyence FA-M3 Series PLC.



RS 232 Communication Between Keyence PLC and Omron NV HMI :-



There are to methods for making a physical connection between HMI & PLC. Either we can connect through Personal Computer Link Module OR Direct Connection to CPU Module. We will see the communication cable diagram for both the types of connections.


||Connecting through a Personal Computer Link Module||



For making this type of connection you need to have the Link Module F3LC11-1N or F3LC11-1F or F3LC12-1F. Make the cable with the following connection diagram.

PLC Side ----------------------------------------------------------------------HMI
Pin 2(RD) -----------------------------------------------------------------Terminal 4(SD)
Pin 3(SD) -----------------------------------------------------------------Terminal 5(RD)
Pin 5(SG) -----------------------------------------------------------------Terminal 8(SG)

Note:- Also short the Pin 4 and 6 , Pin 7 and 8 at the PLC Side.



||Direct Connection to CPU Module||



For this type of communication scheme you will need the KM11-2T Programming Tool Cable. Make the connections as shown below.

PLC Side ----------------------------------------------------------------------HMI
Pin 2(RD) -----------------------------------------------------------------Terminal 5(SD)
Pin 3(SD) -----------------------------------------------------------------Terminal 4(RD)
Pin 5(SG) -----------------------------------------------------------------Terminal 8(SG)


Note:- Also short the Pin 4 and 6 , Pin 7 and 8 at the PLC Side.

Now after making the hardware connection as per your suitability , we have to make some settings both at PLC and HMI side.


|| Settings in NV Designer for Keyence Plc||



NV Designer is the HMI software used to make the screens in NV HMI. Open the NV designer software , Create a New Project and select the proper NV HMI Model which you are using and after that in PLC Type select "Yokogawa FM-M3 Series" and then click Next and select System Memory Area accordingly.


Now we have to define Communication Parameters Both at HMI and PLC side. To set the Communication Parameters in the NV Designer go to PT----NV Configuration and under Communication Parameter Tab select baud Rate as 19200Kbps , Data Bit as 8 , Stop Bit 1 and Parity as None and check sum Enabled.


Also make the following settings in Keyence FA-M3 series PLC:-


Station number--------->> 1
Baud rate--------->> 19,200 bps
Data bits--------->> 8
Stop bits--------->> 1
Parity--------->> None
Checksum--------->> None
End character specification--------->>Enabled
Protection--------->> None

After doing the step by step procedure as told above , you can communicate the NV HMI with keyence PLC easily . Make a sample screen in NV HMI , and test the communication.
