Memory leak occurs when the original OpenOPC package connects to an OPC DA server (WinCC etc.) and SyncRead or SyncWrite some tags.
It is a serious problem, especially in plant situation. This project is aimed to solve it, and provide a window‘s native DLL for Python, so as to leverage advantages of both programming languages. The final software should run on old windows boxes to collect PLC data in WinCC OPC DA Server.
Test enviroment is assumed as WinCC7.0 and Windows7 x86 sp1.
我刚接触opcda,关于SyncRead()这个方法会出现内存泄露的情况吗?其次有关SyncRead()这个方法文档上ServerHandles的参数我始终不清楚是什么.
