Are you looking for ways to connect an FX2N clone to an Arduino using RS232 or 485A and 485B pins? I am interested in linking it to an Arduino Uno via TTL, but I am unsure of the setup and programming needed for integration. This is my first time using a PLC as well.
While there is a similar post about reading data from a PLC, this situation involves a clone where both the 232 and 485 ports are set as programming protocols. Typically, the FX2N 232-BD board is used, but it is not supported by these clones. There is a manual available for communication, but the programming protocol is not widely known. However, it may be helpful to consider the 485 port as a secondary port. For more information, you can refer to this manual: [link].
To connect your FX2N clone to an Arduino Uno, you'd likely use a RS485 module which connects to the Arduino's RX and TX pins for TTL communication. You will have to utilize 485A and 485B pins for RS485 differential transmission. You'll need to use a SoftwareSerial library or similar to handle serial communication on those pins. If it's your first time handling PLC, I'd suggest running some basic programs to understand how it works before moving on to complex integration. There are many online resources and tutorials which can help you with the PLC programming part.
For interfacing your FX2N clone with an Arduino Uno, you'd typically use an RS485 module. The key is to connect the FX2N RS485A and RS485B to the corresponding pins on the RS485 module, and then connect the module's UART pins to the Arduino's TX and RX. You can power the module directly from the Arduino. To handle the programming part, you'll need to use the Arduino's SoftwareSerial library to setup RS485 communication. There are also numerous examples available online that could be helpful as a starting point for your code. Remember that the baud rate should match the PLC settings (generally 9600 baud). This is definitely a fun project, but might require a bit of patience and tinkering to get it running smoothly, especially if it's your first time with a PLC. Good luck!
