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 .
