Hi.
I have a Siemens HMI that is faulty and was wondering if anybody knows whether my following idea would be a quick solution to getting the program backed up to a CF card from the HMI.
When the HMI is powered up it just has a white screen. You don't get to see the bootloaded, the menu to access the control panel, or even the actual program that is running in it. I know there is something running in it as I was doing some dev work then the next time I powered it on the screen didn't work. I also know that it is working because when I press the screen in places it bleeps. And when the screen changes from the load menu (transfer, run etc) it blinks as though the HMI program is then running (still can't see anthing though).
So the idea I had to get into the control panel and backup the program to a CF card was to take the HMI apart then connect a smaller screen (the faulty HMI is a 12" and I have a 10" that works) to the connections on the faulty panel. So the 10" screen would be connected to the faulty HMI in order to get to the control panel.
Would this solution work, or would the connections from the 12" panel damage the 10" screen? I wouldn't want to damaged both of my HMI's!
Thanks for the help
