少有人走的路命名空间：netMarketing.automation.plc.OmronPlc
功能：基于欧姆龙RS232 Host Link Fins协议通讯类
功能详细说明：
欧姆龙PLC的 Host Link Fins通讯协议是一种帧通讯协议，它可以批量读取或者写入数据到PLC内存区，支持DM, A, W, T, CIO, H 等内存区，并且可以读了字或者位。另外，HostLink协议只支持读取监视模式下的数据，而Host Link Fins协议无论在监视还是运行模式下都是可以读写的。
对于hostlink Fins通讯帧，可以参考下面贴子的说明：

常用函数列表：
/// fins指令的数据类型字段枚举:Bit,Word,CompletionFlag,EMcurrentBankNo,PV,Status
public enum finsDataTypeEnum
/// fins指令的区域类型:CIO,DM,W,H,T,A
public enum finsAreaTypeEnum
/// 是否成功连接上plc
public bool IsConnect
/// 构造函数，由SerialParamType定义串口参数
public OmronPlc(SerialParamType serialConfig)
/// 构造字符串格式为： COM1,9600,8,2,N
public OmronPlc(string serialConfig)
/// 设置串口配置，由SerialParamType进行配置。当使用空参数构造函数后，才需要调用本函数配置串口
public void setSerialConfig(SerialParamType serialConfig)
/// 发送基于hostlink协议的字符串，以测试plc是否可以正常通讯

string unitNo = "00", string ResponseWaitTime = "0")
/// 欧姆hostlink通讯协议计算校验码fcs
public string fcs(string Str)
/// 从fins结果串中提取结果值,例如结果串为@00FA004000000001010000 6162 40* 则本函数提取值为6162
public string getValueFromFinsStr(string finsString)
/// 将plc内存的十六进制字(两个字)转为32位的浮点数
public float getFloat32(string data)
/// 把十六进制串转为二进制字符串
public static string toBinary(string ox)
/// 读CIO
/// </summary>
/// <param name="cioAddr">CIO地址，比如101</param>

读内存举例：
（1） 读CIO 101，假设101.0， 101.1 为点亮为1， 其它位为0
内存类型为CIO，数据类型为Bit，地址为101，读取数量为2
@00FA004000000001010000010143*
内存类型为CIO，数据类型为Word，地址为101，读取数量为1
@00FA004000000001010000000340*
勇哥把结果用红色标记出来了。
