R.Mozes Posted February 28, 2016 Report Share Posted February 28, 2016 Hello, Try as follow: Turn off the PLC Touch and hold the screen Power on while screen is touched Touch twice Update the BinLib, Boot and O/S (115200 baud rate, 1 sec timeout) Download a blank project If it didn't helped, contact support@unitronics.com with the results.

Andrus Posted March 5, 2016 Author Report Share Posted March 5, 2016 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 Quote Link to comment Share on other sites More sharing options...
