B–63010EN/02
160
3220 Password
[Data type] 2–word
[Valid data range] 0 to 99999999
This parameter sets a password.
When a value other than zero is set for this parameter, it is regarded as
being a password. Once a password has been set, the display of the setting
(password) field is cleared. In addition, program display, input/output,
and editing operations are locked.
The parameter can be set when the parameter is unlocked, that is, when the
parameter is 0, or when the value of this parameter is the same as the
keyword (parameter No.3221).
CAUTION
This parameter is used to encrypt keys and programs.
3221 Keyword
[Data type] 2–word
[Valid data range] 0 to 99999999
When the same value as the password is set in this parameter, the lock is
released (unlock state). The value set in this parameter is not displayed.
CAUTION
This parameter is used to encrypt keys and programs.
3222 Program protection range (minimum value)
3223 Program protection range (maximum value)
[Data type] 2–word
[Valid data range] 0 to 9999
Those programs whose program numbers are within the range set in these
parameters can be locked. These parameters set the minimum and
maximum values of the program numbers to be locked.
Example: When the minimum value = 7000 and the maximum value =
8499, programs O7000 to O8499 are locked.
When the minimum value = 0 and the maximum value = 0,
programs O9000 to O9999 are locked.
3225 Cipher of safe parameter for dual check safety function
[Data type] 2–word
[Valid data range] 0 to 99999999
Set a cipher (password) for protecting a parameter related to dual check
safety (safety parameter) from change. If a cipher for a safety parameter is
set, the safety parameter is locked. Meanwhile, the setting (cipher) is
displayed as blank characters, and the safety parameter cannot be input.
An attempt to input a safety parameter while locked results in
