There is no "backdoor" password for GE Fanuc PLCs. You will need to get the password from the builder of the machine.

Are you sure you set the password for level 4 and not for OEM protection?

I'm also assuming you're not trying to use the colon ":" character as part of the password.

According to what is showing on the screen you are currently at level 4 access. Are you trying to assign a Level 4 password to a PLC that currently doesn't use one? What message do you get when you press "Y" from the screen shown?

I think you need to stop the PLC in order to set a password. The password is part of hardware configuration and you have to stop the PLC to change hardware configuration.

sorry for giving you  a lack information because of I am not good in English very well . so the showing on the screen is example for creating ( password steps did it in my lab inside Workshop . Note : Not on the Equipment )  But in certainly ( Reality ) the Equipment problem I can't reach the password level 4 . 

Note : the program is not allow you to reach level 4 Because when I enter password DE94 gives wrong password ( Not allow ) .

Here are the 2 Questions : 

1- I Re installed the PLC program . Does It cause any problem to use password ? Note : Before installing the PLC program , We kept the folder LM90 then I re installed the program then Back the Original the folder LM90 to old Its position .

2- If someone guesses the password . Does the program get confusing later ? Note : When we check the program table fault , Found many / lots Times someone tried to access / Entered password . 

is there another solution to re set the password without removing battery backup Or Replacing power supply ? 

due to the Equipment always is operation and we don't need to lose the register / Data . 

 thanks.

Upload the program logic and reference tables from the PLC. Create a new project file and copy what you just uploaded to it. Manually configure the CPU settings and module information in the new project file. Download to a spare CPU and install it in place of the one currently working. Once you are satisfied that it is working properly you can clear the memory in the original.
