Modbus封装库(Com,tcp,udp一应俱全)

自行封装在用的Modbus通迅库,集成了com,tcp,udp, 做个笔记吧， 以下头文件，

#pragma once

#include <functional>

#include <vector>

#include <string>

#include <memory>

#ifdef LIBMODBUS_EXPORTS

#define LIBMODBUS_EXPORT_API __declspec(dllexport)

#else

#define LIBMODBUS_EXPORT_API __declspec(dllimport)

#endif

class LIBMODBUS_EXPORT_API RTUModbus {

public:

//devflag is 1 as default value

RTUModbus();

~RTUModbus();

public:

std::string getAddrPLC();

uint16_t getDevflag();

int getPort();

void sendBit(uint16_t addrstart, bool mvalue);

bool readBit(uint16_t addrstart, uint8_t* destBit);

void sendDataRegister(uint16_t addrstart, uint16_t mvalue);

void sendDataRegisters(uint16_t addrstart, uint16_t* mvalue);

void sendDataRegisters(uint16_t addrstart,const int len, uint16_t* mvalue);

bool readDataRegisters(uint16_t addrstart, uint16_t* destBit);

bool readDataRegisters(uint16_t addrstart,const int len, uint16_t* destBit);

bool isConnected();

void setPLCParam(const int mport, std::string ipra);

void disconnect();

bool connectPLCbyNet(const int port, const int devflag, std::string addr);

bool connectPLC(const int devflag);

//mport :com1 ,flag:0 Rs232,1:RS485

bool connectPLCbySerial(const char * mport, const int flag, const int baud = 115200,

char parity = 'N', const int data_bit = 8, const int stopbit = 1);

bool connectTo_UDP(std::string strIP, const int mport);

private:

std::shared_ptr<void> _modClient;

};

应用标例：

RTUModbus* mBus=new RTUModbus();

网口连接：

//tcp:

bool res=mBus->connectPLCbyNet(9000,1,"192.168.3.58");

//udp

bool res=connectTo_UDP("192.168.3.58",9000);

串口：

bool res=connectPLCbySerial("com1",1,115200);

读写方式，三者（串口、网口tcp,udp）都是共用的
