Hi ! I tried as R.Moses guided and succeed to install BinLib and Boot
Then tried to install OS , but it got error on PC screen during update.
Contacted Unitronic Tech support and from there got an extra tip:
Try as follow:
Turn off the PLC
Touch and hold the screen. Power on while screen is touched. You will see a countdown on the PLC screen. Touch the HMI screen twice . The countdown should have stop. On VisiLogic configure the communication settings with a baud rate of 115200 and a timeout of 1 sec First update only the BinLib When BinLib has finished updating, please update only the Boot When Boot has finished updating, update only the O/S. Download a blank project
Tried many times to update O/S, but it stopped during install.
as last effort I just refrain using computer, went to have dinner and when came back, it was OK
