Jay12 Posted March 20, 2011 Report Share Posted March 20, 2011 Hello, I am having an issue when downloading to the PLC, I get an error displaying Error 391-Visilogic failed to download images to the PLC.

Nikita Petrov Posted June 15, 2015 Report Share Posted June 15, 2015 Hello everyone! Theme up, I have faced the same problem. I'm guessing, it's beause of bad sectors in flash memory - images download stops at sector 11 of flash memory, then returns error 391. Is it fixabe? PLC is V1040-T20B. Regards.
