OLAF Posted June 9, 2022 Report Share Posted June 9, 2022 Dear All, I am having a strange problem in establishing the connection between a USL-156-B05 Unistream display and a PLC type USC-C10-RA28. I am honestly not sure, if I have caused this in program, or if the screen has a problem. Everything was working fine for a while, but after a program update the screen cannot make the VLC connection anymore (yep....usually hints to a program fault). After a program download the screen is trying to connect for a while, but ends with the error message of not being able to establish a connection. A ping to the PLC is successful. A remote VNC connection to the panel IP using a laptop is working. The VNC connection settings on the panel is a bit strange, since "Apply" and "Cancel" buttons are both 'greyed' out, without showing any action when pressed (see hereafter): Does anyone have an idea, why this has stopped working? Any help is highly appriciated. Regards, Olaf IO TEST SOFTWARE.ulpr Quote Link to comment Share on other sites More sharing options...
