// 假设你要读取连续地址数据的情况，我们把需要读取的数据解析成一个个不同的数据类型，则可以使用本方法。
// 我们假设，我们要读取的PLC是西门子PLC，地址数据的假设如下
// 我们假设 设备是否启动是 M0.0
// 产量是 M10 开始的2个地址数据
// 温度信息是 M12开始的4个地址数据
// 报警的IO信息是 M20 开始，5个字节，共计40个IO点信息
// 那么我们可以做如下的定义

public class StructExample
{
    /// <summary>
    /// 设备是否启动
    /// </summary>
    [HslStruct( 0 )]
    public bool Enable { get; set; }

    /// <summary>
    /// 产量信息
    /// </summary>
    [HslStruct( 10 )]
    public short Production { get; set; }

    /// <summary>
    /// 温度信息
    /// </summary>
    [HslStruct( 12 )]
    public float Temperature { get; set; }

    /// <summary>
    /// 连续的位报警信息
    /// </summary>
