lwmar posted a topic in MitsubishiDear 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
Has somebody experience with Chinese PLCs like Haiwell. I saw this brand on a Dutch website. It's cheap, free development tools and free (cloud based) SCADA, simulator build in. A bit Siemens look-a-like at the outside. Has somebody done a project with Haiwell? Or with other Chinese PLC brands. Please let me know about your pro's and con's because my customer wants to use it for packaging machines. Thanks in advance.
