我的程序某块代码执行很慢。好的时候，十几毫秒，坏的时候几万毫秒，甚至更高。


这块代码主要目的是初始化PLC（倍福），同时写入数据也会很慢。如果好的话，写入和初始化都正常。


关键是程序跟神经一样，上午好好的，下午可能就不行，今天好，明天就不行。一会好，一会坏，重启电脑也没用。


计算机初学者，没有思路，跟CPU和内存使用率关系不大。今大家指点方向！！！。


PLc相关：

#include "C:\TwinCAT\AdsApi\TcAdsDll\Include\TcAdsDef.h"
#include "C:\TwinCAT\AdsApi\TcAdsDll\Include\TcAdsAPI.h"
LIBS += C:\TwinCAT\AdsApi\TcAdsDll\Lib\TcAdsDll.lib
C:/Program Files (x86)/Microsoft SDKs/Windows/v5.0/Include/WinDef.h（lib需要用到）

首先，看你初始化和读写的时候，调用的函数名，都是同步函数比如AdsSyncReadWriteReq，如果双方通信线路或有一方机器出了些许问题，一直在校验丢包的话，可能要重发很多次才能成功。

或者下位机PLC很忙碌，没空理上位机，上位机同样需要等待很久很久。

1、如果你确认它们没故障，可以调用库提供的【异步函数】；
2、或者你在开【一两个线程】初始化和读写，明确告诉用户正在初始化和读写，让用户等待；
3、换一台好的PLC再试试，确认你的电脑和PLC都没问题。
