Giddings & Lewis PIC 900 PLC controller Password
Giddings & Lewis PIC 900 PLC controller Password
(OP)
I have a G&L PIC 900 controller hooked up to an older machine that I need to enter a Password A and a Password B into the PIC in order to make an adjustment on a Siemens Drive that is hooked in to the PIC controller. The PIC is about 10 years old and I have not needed to make any adjustments to the machine since the controller was installed. I have had in house maintenance electricians retire and leave the company and for whatever reason the passwords were not recorded. Is there a default password that will allow me access to the PIC controller? The last passwords were four digit numbers, but in order for me to change a password I need to enter the old one which I have but it does not work. Any suggestions or ideas, I need help.

A hand written closed top 4 can look like a 9.
Some really sloppy rounded 5's can look like 6's.
A hand written European 7 with a slash can look like a 9 to an American.
