You can get a spare CF card and put a basic B&R program on it that is just one big calibration button to calibrate the HMI if you can't figure out how your existing program triggers screen calibration. The calibration file is stored on the CF card, you can copy it from that CF card to the exiting project's CF card or even just delete the faulty calibration file from the existing CF card via FTP. I forget the file name, probably something starting with 'vc' (they call their HMI system Visual Components), maybe 'vccalibdata' or something like that.
Hello,
I am having the same problem, but with 4PP420.1505-B5. After I calibrated the touch screen, at the CF disk a folder with some files were created (folder name ADDON).
I copy this folder on other CF (the same program, but without calibration), and nothings happens. The calibration doenst work.
Any ideias?
I am glad for any help that guides me to a solution.
