Posted 14 Dec 2015 Hi everyone. I created project in Visual Studio 2010 using MX Component (AxActQJ71E71TCP Control). It seems everything works normally. But when I turn off PLC or remove Ethernet cable from the QJ71E71 module my windows form gets frozen. My question is how to define lost connection in case of turning off plc or removing cable and inform user about it. Is there any event handler in VS or any way to find solution? Thanks.

Posted 17 Dec 2015 Use try-catch maybe? Or create an error handler that handles any comm errors? Share this post Link to post Share on other sites
