In order for a user to login, they must first enter their user number into reserved local word LW9219. Then they must
enter their password into reserved local word LW9220 (32-bit unsigned).
This procedure is different from what was used in EasyBuilder-500, where the user only needed to enter a
password.
There are several other reserved local words and bits that can add functionality to your security implementation.
Reserved Local Memory
Function
LW9222
Displays the access levels assigned to the currently logged-in user
in binary format (16-bit binary)
Bit 0: A, Bit 1: B, Bit 2: C, Bit 3: D, Bit 4: E, Bit 5: F
LW9500-LW9523 (32-bit unsigned)
Stores user passwords 1-12
LB9050
Logs out user and resets password to zero when bit is set (HMI
resets bit to zero)
LB9060
Indicates when an invalid password has been entered (bit resets
to zero when valid password is entered)
LB9061
Set to update user passwords when changed locally
(LW9500-LW9523) Use momentary style

registers in a security implementation.
