Please recommend a 485 software
Thread Content
There is a flow meter that outputs 485 signals, and I’m looking for software to read these signals in order to view the instantaneous flow rate and cumulative flow volume. However, I’m not familiar with such digital signals; I’d appreciate some recommendations. I found many results on Baidu, but all the downloads led to P2P download links, and after downloading them, I ended up with lots of advertising games
After I installed it, I got the same interface as you, and the instrument was connected properly as well as the ports; there seems to be nothing else that’s wrong. How can I read the data?
This is just a debugging tool; you still need to write the sending and receiving programs. Is PLC Modbus communication that complicated? I specifically bought a 485 instrument for you to teach you Modbus communication from scratch: https://www.bilibili.com/video/BV18J411p7LZ. Alternatively, you can use one of the software programs such as KingView, MCGS, or LC-Control to communicate with the instrument and retrieve data from it. I haven’t tried it either; please correct me if I’m wrong. This is for reference only
You need the manufacturer to provide the communication protocol.
modscan is more suitable for beginners, while the serial port debugging tool is more convenient
