Password setting
■

Enter the current security password.
■
New password and confirmation password
To change the security password, enter a new security password in "New Password" and "Confirm New Password".
Precautions
■
CW Configurator operation
When the CW Configurator operation is disabled, the parameters cannot be set. To enable the service, initialize C Controller
module.
■
Memory card parameter execution
To select an SD memory card as a target memory of the parameters, enable "Memory card parameter execution". ("Disable"
is selected as a default.)
■
Stopping multiple services
When the memory card access is disabled, the memory card script execution will be disabled as well.
Locked out
If the password authentication failed for several times, the password authentication will be denied (locked out) for a period of
time. This prevents a brute force attack from unauthorized users.
Lockout time
The lockout time is as follows:
*1 Once the correct password is entered, the number of password input error will be cleared.
• The password input error will not be counted during lockout. Therefore, the lockout time will not be extended
additionally by one minute even if the 7th input error occurs before one minute has passed since the 6th.
• When the security setting is configured using the C Controller module dedicated function
(CCPU_ChangeFileSecurity), the password authentication will not be locked out.
