使用NModbus的Modbus

Question

尝试使用以下代码使用NModbus在端口上发送数据。此处的目的是通过Modbus协议将数据发送到PCBA。

private bool SendDataToBoard1(byte slaveId, SerialPort Port, MainScreen.ParametersSendToModbusProtocol ParameterToWrite, MainScreen.modbusConfigPara modbusCongiData)
    {
            //Port.Close();

            //string portName = Port.PortName.ToString();

        using (Port = new SerialPort("COM4"))
        {
            Port.BaudRate = 115200;
            Port.DataBits = 8;
            Port.Parity = Parity.Even;
            Port.StopBits = StopBits.One;
            Port.Open();
            var adapter = new SerialPortAdapter(Port);
            // Create the factory
            var factory = new ModbusFactory();

            // Create Modbus Master
            IModbusMaster master = factory.CreateRtuMaster(adapter);

            // IModbusSerialMaster master = ModbusSerialMaster.CreateRtu(Port);


            int temp = ushort.Parse("1") - 1;
            //byte slaveId = modbusCongiData.SelectedREVBoardNo;
            ushort startAddress = (ushort)(temp);
            ushort points = modbusCongiData.BytesToRead;
            ushort[] data = new ushort[120]; //123 Max characters

                master.WriteMultipleRegisters(slaveId, startAddress, data);

                return true;
            }
            catch (Exception ex)
            {
                log.Debug("Error in SendDataToBoard1", ex);

                return false;

            }
        }
    }

应用程序在遇到时挂起

  

master.WriteMultipleRegisters（slaveId，startAddress，data）;

这是怎么了？以及如何实现Modbus数据传输？使用git中的NModbus库。

谢谢。

因此，通过添加以下两行，应用程序不再挂起，但我仍然无法在端口上发送数据。

            adapter.WriteTimeout = 2000;
            adapter.ReadTimeout = 1000;
