    Dear manjey73,
    Thank you for your reply.
    When i done a command: Sudo lsusb, i saw this “Bus 001 Device 004: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter”. I did not see any /dev/ttyUSBx.
    Maybe have to use another USB-RS485 converter, for example USB-RS485 converter FT232.
    Thanks

    Dear Mr.Mikhail,
    I want to note that the RS485-USB converter is recognised by Raspberry Pi4:
    “Bus 001 Device 004: ID 1a86:7523 QinHeng Electronics HL-340 USB-Serial adapter”
    Thank you again

    Dear Mr.Mikhail,
    To continue this topic, i need your help. My project is working properly on Raspberry Pi4. Many RS485 devices are communicating with server on Raspberry Pi4 via RS485-WiFi converter (TCP/IP), but unusable. Now i want to replace a Modbus TCP/IP protocal by Modbus RTU. That’s mean the RS485-USB converter will be used. So could you let me know how to configure the PortName for USB on Rapid Scada Communicator?
    Thanks and best regards

    Dear Mr.Mikhail,
    On topic” Send command” i asked you this question: “That means Press the Button, the value will be 1, released the Button, past some second, the value auto will be 0. I do likes that, don’t i?
    You answered that: “I also would choose this method.
    When a user click the button, the 1st command is sent. Then you need Automatic Control Module that triggers on the 1st command and automatically sends the 2nd command after the specified delay.”
    Thanks

    Dear Mr.Mikhail,
    The Module auto control was activated. The first I am using a trial key on Windows, then it will be uploaded to Raspberry Pi4. So Could you let me know step by step to configure to send a release command?
    Thanks and best regards

    Dear Mr.Mikhail,
    So i think the second way is better for me. That means Press the Button, the value will be 1, released the Button, past some second, the value auto will be 0. I do likes that, don’t i?
    Thanks again
