少有人走的路命名空间：netMarketing.automation.plc.OmronPlcNet
功能：OmronPlc基于tcp的Fins读写类。可用NJ系列，CP1H系列的欧姆龙PLC
功能详细说明：
OmronPlcNet类是基于tcp的Fins通讯类。可用NJ系列，CP1H系列的欧姆龙PLC。
常用函数列表：
/// 构造函数 public OmronPlcNet(Byte clientNode, Byte serverNode) /// 初始化plc端口连接 public bool InitPort(string IpAdrr, int Port) /// 关闭连接 public void Close() /// plc是否连接上了 public bool IsConnected /// plc握手协议 public bool Handshake() /// 重新连接plc public bool ReConneting() /// 读数据,double型 public Double[] ReadDouble(UInt16 startAdrr, UInt16 readLength, Byte AreaType) /// 写数据,double型 public bool WriteDouble(UInt16 startAdrr, Byte AreaType, params Double[] doubleData) /// 读字符串 public string ReadString(UInt16 startAdrr, UInt16 readLength) /// 读数据,Single型 public Single[] ReadSingles(UInt16 startAdrr, UInt16 readLength, Byte AreaType) /// 写数据,single型 public bool WriteSingles(UInt16 startAdrr, Byte AreaType, params Single[] singleData) /// 读数据,int16型 public Int16[] ReadInt16(UInt16 startAdrr, UInt16 readLength, Byte AreaType) /// 写字符串 public bool WriteString(UInt16 startAdrr, params byte[] byteData) /// 写数据,int16型 public bool WriteInt16(UInt16 startAdrr, Byte AreaType, params Int16[] Int16Data) /// 读数据, int32型 public Int32[] ReadInt32(UInt16 startAdrr, UInt16 readLength, Byte AreaType) /// 写数据, int32型 public bool WriteInt32(UInt16 startAdrr, Byte AreaType, params Int32[] Int32Data) /// 读位, 返回bool型 public Boolean[] ReadBits(UInt16 startAdrr, Byte bitNo, UInt16 readLength, Byte AreaType) /// 写位 public bool WriteBits(UInt16 startAdrr, Byte bitNo, Byte AreaType, params Boolean[] BoolenData)
