Posted 14 Apr 2016 I am working on a system with a siemens plc and HMI using TIA Portal V13 and WinCC. I wanted to remove to buttons from the HMI so the operator no longer has access to them. I removed them in the project (saved them on a temporary screen). When I uploaded the changes to the HMI, the buttons still exist. I also tried the simulator and I had the same results. Do I need to manually un-register the buttons somewhere? Also, I made a new screen and changed one of the screen change buttons to direct toward it. When testing it, a blank screen showed up instead of the screen that I directed it to. I have done a lot of plc/hmi programming in the past, but I have never experienced symptoms as such. I am new to the Siemens world. I have traditionally used AB products. Are there a lot of nuances with WinCC that I am unaware of? Kris Share this post Link to post Share on other sites
Posted 14 Apr 2016 If you select the button and press delete, then select the hmi and compile and then download it should be gone. My guess is you are not selecting the whole hmi when you compile and download. 1 person likes this Share this post Link to post Share on other sites
