Hello,
I have the following python code:
client = ModbusSerialClient(method='rtu', port="/dev/ttymxc3", baudrate=38400, timeout=1000) client.read_holding_registers(646, unit=10)
Reading registers does work with Python, but with Go modbus it does not work:
client, err := modbus.NewClient(&modbus.ClientConfiguration{ URL: "rtu:///dev/ttymxc3, Speed: 38400, Timeout: 1 * time.Second, }) if err != nil { return nil, err } err = client.SetUnitId(uint8(10)) if err != nil { return nil, err } err = client.Open() if err != nil { return nil, err } client.ReadUint32(364, modbus.HOLDING_REGISTER)
I tried the modbus-cli as well and even that does not work: /modbus-cli --target=rtu:///dev/ttymxc3 --speed 38400 suid:10 rh:uint16:364
Found the issue... I had to set a different stop bit (1) instead of 2.
