Abby Posted February 9, 2022 Report Share Posted February 9, 2022 Hello, I am having trouble with my hmi screen (USL-050-B05) connected to the plc (USC-B3-R20). When I download the basic program and hmi screen into the plc/hmi using Unilogic. A clear yet grey film sits on top of my hmi. This is not allowing me to press any buttons on my HMI, It is completely unresponsive. When I enter online mode on my computer, the hmi screen become grey as well. UPDATE: I have found the solution. I assigned the tag (which was not active at the time) and it blocked the button from being pressed. In the properties window under Tag: touch Enabled.
