I upload the application "a.pvd" from Panelview1000e(2711E-T10C15).And open the a.pvd in the panelbuilder 1400e(release 5.11) software,then save the application a.pvc without any change.I create the a.pvd again,and download the a.pvd which I created just now. And the a.pvd can not work,the panelview display a message"CNet## : Remote station has not replied within specified timeout period."But the old application a.pvd also can work now. Could you tell me the reason? I want to change some screens in the application.But if this problem doesn't solve,I can't make any change with the application.Do me a favor please,thank you in advance.
