To use Modbus in C#, you first need to install a Modbus library such as NModbus. Then, you can use Modbus by following these steps:<\/p>\n

    \n
  1. Import the NModbus library:<\/li>\n<\/ol>\n
    using<\/span> Modbus;\r\n<\/code><\/pre>\n
      \n
    1. Set up Modbus master:<\/li>\n<\/ol>\n
      IModbusMaster master = ModbusSerialMaster.CreateRtu(port); \/\/ \u4f7f\u7528\u4e32\u884cRTU\u901a\u4fe1<\/span>\r\nIModbusMaster master = ModbusTcpMaster.CreateTcp(ipAddress); \/\/ \u4f7f\u7528TCP\u901a\u4fe1<\/span>\r\n<\/code><\/pre>\n
        \n
      1. Connect to Modbus slave:<\/li>\n<\/ol>\n
        master.Connect(); \/\/ \u8fde\u63a5\u5230\u4ece\u673a<\/span>\r\n<\/code><\/pre>\n
          \n
        1. Read the registers of the Modbus slave:<\/li>\n<\/ol>\n
          ushort<\/span> startAddress = 0<\/span>; \/\/ \u8d77\u59cb\u5730\u5740<\/span>\r\nushort<\/span> numRegisters = 10<\/span>; \/\/ \u5bc4\u5b58\u5668\u6570\u91cf<\/span>\r\nushort<\/span>[] registers = master.ReadHoldingRegisters(startAddress, numRegisters);\r\n<\/code><\/pre>\n
            \n
          1. Write registers to Modbus slave:<\/li>\n<\/ol>\n
            ushort<\/span> startAddress = 0<\/span>; \/\/ \u8d77\u59cb\u5730\u5740<\/span>\r\nushort<\/span>[] registers = new<\/span> ushort<\/span>[] { 1<\/span>, 2<\/span>, 3<\/span>, 4<\/span>, 5<\/span> }; \/\/ \u8981\u5199\u5165\u7684\u5bc4\u5b58\u5668\u7684\u503c<\/span>\r\nmaster.WriteMultipleRegisters(startAddress, registers);\r\n<\/code><\/pre>\n
              \n
            1. Disconnect from the Modbus slave:<\/li>\n<\/ol>\n
              master.Disconnect(); \/\/ \u65ad\u5f00\u8fde\u63a5<\/span>\r\n<\/code><\/pre>\n
              This is just the basic usage of Modbus, specific operations may vary depending on your needs. Other Modbus functions such as reading input registers or writing to single registers can also be used as needed.<\/p>\n","protected":false},"excerpt":{"rendered":"
