Hello friends! I am looking to connect my FX2N PLC with my Arduino Mega using a TTL-RS232 and RS232 cable. I want to program the Arduino to activate output Q0 of the PLC when pin 7 is activated, and activate output pin 8 of the Arduino when input X0 of the PLC is activated. I am using FLOWCODE for Arduino programming and GX Developer for the FX2N PLC. Thank you for your assistance.
Seeking assistance from knowledgeable forum members, I am looking to connect my PLC FX2N with my Arduino Mega through RS232 communication. I aim to establish a system where activating a pin on one device triggers a corresponding action on the other. Utilizing a Modbus master-slave setup, I believe this can be achieved with programming. I am using the GX Developer for the FX2N PLC and Flowcode for Arduino. Any guidance on integrating these systems would be appreciated.
The FX2N, although an older model with a 422 port for programming, requires the use of the MC protocol, which can be challenging. Additional options for 232 connectivity include add-ons that can be attached to either side of the processor, such as the 232 IF interface acting as an I/O card. These add-ons support various protocols, with ASCII being the most straightforward. While the FX2N has been phased out, the FX3 is its successor and offers similar functionalities.

Hello there! I am looking to establish communication between an Arduino and a Mitsubishi FX2N PLC, but I'm unsure about the process involving RS232 or RS485. Essentially, I want to trigger a response from the Arduino (either through pin 7 or pin 8) when a button on input X0 of the PLC is pressed. Can anyone provide guidance on how to achieve this integration effectively?
I am unsure if I can provide a picture of the PLC model 2N-B-52MR and the corresponding cable (DealMux RS232 to RS422 adapter cable for Mitsubishi).
Is there anyone who can assist with connecting FX2N to Arduino?
It sounds like you have a solid plan laid out! Remember, for the communication between the Arduino Mega and the FX2N PLC, you'll need to use the Serial communication feature provided by Ardunio and establish the correct baud rate in your FLOWCODE software. Additionally, make sure to correctly align the logic voltage levels between them using your TTL-RS232 converter. For the specific pin mappings, you'll need to write those logic conditions in your Arduino code - give digitalRead/digitalWrite functions a go maybe. Lastly, for the PLC side of things using the GX Developer, ensure the corresponding input and output references match your Arduino pinout. It'll be a great learning experience, good luck!
