首先添加引用 三菱PLCdll文件
1、导入 命名空间：
using HslCommunication.Profinet.Melsec;
2、声明一个PLC对象：
private MelsecMcNet melsecMcNet = null;
3、读取PLC地址值
///
/// 读取bool值
///
/// PLC地址：如M100,X100,Y100,B100
///
public bool ReadBool(string str_Add)
{
OperateResult rt = this.melsecMcNet.ReadBool(str_Add);
if (rt.IsSuccess)
return rt.Content;
else
return false;
}
///
/// 读取short值
///
/// PLC地址：如D100,W100,R100
///
public int ReadInt16(string str_Add)
{
OperateResult rt = melsecMcNet.ReadInt16(str_Add);
if (rt.IsSuccess)
{
return rt.Content;
}
else
{
return 0;
}
}
///
/// 读取ushort值
///
/// PLC地址：如D100,W100,R100
///
public int ReadUInt16(string str_Add)
{
OperateResult rt = melsecMcNet.ReadUInt16(str_Add);
if (rt.IsSuccess)
{
return rt.Content;
}
else
{
return 0;
}
}
///
/// 读取int值
///
/// PLC地址：如D100,W100,R100
///
public int ReadInt32(string str_Add)
{
OperateResult rt = melsecMcNet.ReadInt32(str_Add);
if (rt.IsSuccess)
return rt.Content;
else
return 0;
}
///
/// 读取uint值
///
/// PLC地址：如D100,W100,R100
///
public int ReadUInt32(string str_Add)
{
OperateResult rt = melsecMcNet.ReadUInt32(str_Add);
if (rt.IsSuccess)
return (int)rt.Content;
else
return 0;
}
///
/// 读取float值
///
/// PLC地址：如D100,W100,R100
///
public float ReadFloat(string str_Add)
{
OperateResult rt = melsecMcNet.ReadFloat(str_Add);
if (rt.IsSuccess)
return rt.Content;
else
return 0;
}
///
/// 读取double值
///
/// PLC地址：如D100,W100,R100
///
public double ReadDouble(string str_Add)
{
OperateResult rt = melsecMcNet.ReadDouble(str_Add);
if (rt.IsSuccess)
return rt.Content;
else
return 0;
}
/// <summary>/// 读取多个连续的bool值/// </summary>/// <param name="str_Add">PLC地址：如M100,X100,Y100,B100</param>/// <param name="length">地址个数</param>/// <returns></returns>public bool[] ReadBool(string str_Add, ushort length){OperateResult<bool[]> rt = this.melsecMcNet.ReadBool(str_Add, length);if (rt.IsSuccess) return rt.Content; else return null; }/// <summary>/// 读取short值/// </summary>/// <param name="str_Add">PLC地址：如D100,W100,R100</param>/// <param name="length">地址个数</param> /// <returns></returns>public short[] ReadInt16(string str_Add, ushort length){OperateResult<short[]> rt = melsecMcNet.ReadInt16(str_Add, length);if (rt.IsSuccess) return rt.Content; else return null; }/// <summary>/// 读取ushort值/// </summary>/// <param name="str_Add">PLC地址：如D100,W100,R100</param>/// <param name="length">地址个数</param>/// <returns></returns>public ushort[] ReadUInt16(string str_Add, ushort length){OperateResult<ushort[]> rt = melsecMcNet.ReadUInt16(str_Add, length);if (rt.IsSuccess) return rt.Content;else return null; }/// <summary>/// 读取int值/// </summary>/// <param name="str_Add">PLC地址：如D100,W100,R100</param>/// <param name="length">地址个数</param>/// <returns></returns>public int[] ReadInt32(string str_Add, ushort length){OperateResult<int[]> rt = melsecMcNet.ReadInt32(str_Add, length);if (rt.IsSuccess) return rt.Content; elsereturn null; }/// <summary>/// 读取uint值/// </summary>/// <param name="str_Add">PLC地址：如D100,W100,R100</param>/// <param name="length">地址个数</param>/// <returns></returns>public uint[] ReadUInt32(string str_Add, ushort length){OperateResult<uint[]> rt = melsecMcNet.ReadUInt32(str_Add, length);if (rt.IsSuccess) return rt.Content; else return null; }/// <summary>/// 读取float值/// </summary>/// <param name="str_Add">PLC地址：如D100,W100,R100</param>/// <param name="length">地址个数</param>/// <returns></returns>public float[] ReadFloat(string str_Add, ushort length){OperateResult<float[]> rt = melsecMcNet.ReadFloat(str_Add, length);if (rt.IsSuccess) return rt.Content;else return null; }/// <summary>/// 读取double值/// </summary>/// <param name="str_Add">PLC地址：如D100,W100,R100</param>/// <param name="length">地址个数</param>/// <returns></returns>public double[] ReadDouble(string str_Add, ushort length){OperateResult<double[]> rt = melsecMcNet.ReadDouble(str_Add, length);if (rt.IsSuccess)return rt.Content;else return null; }/// <summary>/// 读取string值/// </summary>/// <param name="str_Add">PLC地址：如D100,W100,R100</param>/// <param name="length">地址个数</param>/// <returns></returns>public string ReadString(string str_Add, ushort length){OperateResult<string> rt = melsecMcNet.ReadString(str_Add, length);if (rt.IsSuccess) return rt.Content; else return string.Empty; }
