CSoft.Protocol.Modbus 10.0.0

Modbus协议：

IModBusMaster modBus = new ModBusMaster(new SerialPort("COM2"), ModbusType.TCP);
await modBus.OpenAsync();
var b = new BlockList();
b.Add(new ProtocolData());
//var rs = await modBus.GetAsync("01", b);
var rs = await modBus.GetAsync<ProtocolData>("01", b);

// rs 的类型为 List<ProtocolData>
Console.WriteLine($"A: {rs.A}, B: {rs.B}, C: {rs.C}, D: {rs.D}");

public class ProtocolData
{
    [CHProtocol(1, "a")]
    public float A { get; set; }

    [CHProtocol(3)]
    public UInt16 B { get; set; }

    [CHProtocol(4)]
    public float C { get; set; }

    [CHProtocol(9)]
    public float D { get; set; }
}

下边的都过时了

IModBusMaster modBusRtu = new ModBusMaster(new SerialPort("COM2"));
