Passwords

[Guest Matt]

We had a programmer leave on bad terms and password protected a project he was working on. All copies seem to be gone. We can clear the plc and start over again but it has been put into production and down time is a problem. The PLC is a Allen Bradley slc 504. Is there any way of finding out the password so we can save the program?

Hi Open the Ladder File with text editor (I use the Norton comander) For SLC the password is in address B0 For PLC the password is in address C830 I think this will do it. Offer Dahan
