Dear all,
I have a FX2N-20MR chinese semi-clon of a Mitsubishi PLC. It has only a serial DB9 port that cannot be removed or exchanged (which is possible in the Mitsubishi original PLC). I wonder if I can make a simple SCADA system using that port and just one computer.
I am reading this post: https://forums.mrplc.com/index.php?/topic/9653-fx-series-and-modbus/
And I am wondering how I can do what it is suggested there in the second message: to use a free FB block, available in GX IEC (but not in GX Developer), which will communicate modbus via a standard RS232 BD board. Later on it mentions a library called ModbSFX. That message is from 15 years ago so I am wondering if now there is some other way to do it, perhaps some other software has that functionality? I don't have GX IEC.
I am a student trying to make a project so I would like a cheap and simple solution. Any help to do so will be very welcome.
Thanks
Regards
Marcelo
