We've just had a disgruntled engineer leave the company who's locked the PLC with a four digit code. Does anybody know a way around this without having to manually input 10,000 combinations or scraping the PLC?
Hello,
The only way to access the PLC is to manually input 5 times the wrong password with the on-board display. After this you will be asked if you want to delete the program(which will remove the password too). You can find additional info in the manual of the PLC.
Have a nice day.
