I am having problems with some of the icons freezing up on the panel view. The configuration consits of an AB panel view,a Fanuc Robot M-16iAL, AB SLC 500, and Device net. The inputs are functioning correctly I can monitor the stand alone computer running RSlogix and i can see the Photo eyes change states, But on two occassions I noticed several of the icons not updating to the panel view. Could this be a glitch in the Panel view or is something else going on.
