Which model PLC? The password for the Series 90 PLCs is a four-digit hex number. There is no 'super' or administrative password. If you need to modify the current program, you'll need to try all possible combinations until you find the one that works. If you only need to reuse the PLC hardware, you can disconnect the battery and leave the PLC unpowered for an hour or so. That will erase the program and the password, allowing you to reenter the program manually. If you have a listing of the program, that is probably faster than trying 65,535 possible password combinations.
