安装

dotnet add package DL_TCP

使用示例

using DL_ModbusTCP;

// 创建实例
var modbus = new DL_ModbusTCP("192.168.1.100", 502);

// 连接
if (modbus.Connect())
{
    // 读取保持寄存器
    ushort[] registers = modbus.Nmodbus4Tcp_ReadHoldingRegisters(1, 0, 10);

    // 写入单个线圈
    modbus.Nmodbus4Tcp_WriteSingleCoil(1, 0, true);

    // 断开连接
    modbus.Disconnect();
}

主要方法

连接管理

  • Connect() - 建立TCP连接
  • Disconnect() - 断开连接
  • IsConnected - 连接状态

读取操作

  • Nmodbus4Tcp_ReadCoils - 读取线圈
  • Nmodbus4Tcp_ReadInputs - 读取输入
  • Nmodbus4Tcp_ReadHoldingRegisters - 读取保持寄存器

写入操作

  • Nmodbus4Tcp_WriteSingleCoil - 写入单个线圈
  • Nmodbus4Tcp_WriteSingleRegister - 写入单个寄存器
  • Nmodbus4Tcp_WriteMultipleCoils - 批量写入线圈
  • Nmodbus4Tcp_WriteMultipleRegisters - 批量写入寄存器

错误处理

所有操作在未连接时会抛出 InvalidOperationException。建议使用 try-catch 捕获异常：

try
{
    modbus.Nmodbus4Tcp_WriteSingleCoil(1, 0, true);
}
catch (InvalidOperationException ex)
{
    Console.WriteLine($"请先连接: {ex.Message}");
}
catch (Exception ex)
{
    Console.WriteLine($"操作失败: {ex.Message}");
}
