Convta98 Posted July 16, 2022 Report Share Posted July 16, 2022 I tried to download a new program to a SM35 that was similar to what was already in it. I received an error at the end of download that it timed out. I increased baud rate and timeout time. No success. I sent program to Unitronics to check. They suggested I download latest version and try again. I did this and it wanted me to update OS. I went to update OS and it failed on step 2. I tried powering down, remove battery, nothing helped. Now the screen says factory boot error. I cant download program, I cant update OS.... Anyone have a solution? Link to comment Share on other sites More sharing options...
MVP 2023 kratmel Posted July 16, 2022 MVP 2023 Report Share Posted July 16, 2022 Moved... Please read this topics You must also try to use another PC for OS update with hardware RS232 on board. If SM35 hardware is ok - it is impossible to brick Vision series PLC. P.S. Please post Visilogic OS version check menu result for this SM35.

MVP 2023 Ausman Posted July 16, 2022 MVP 2023 Report Share Posted July 16, 2022 As well, what Windows version? Try using W7 if possible. I still haven't found why my W10 has recently made part of the OS update fail. However, my W7 laptop with an Express Card in the slot does it perfectly.
