2-8-15 Passwords (Extension Tab)
A password can be set for when entering data to functional objects during PT operation. Refer to
Common Functional Object Settings in 2-8 Common Functional Object Functions for functional objects
to which passwords can be set.
There are two password functions: the password function and login function.
Password function: The password must be input before an operation on a password-protected func-
tional object.
Password function (with level function): The password must be input before an operation on a pass-
word-protected functional object. Once the password is input, all object operations
allowed at that authentication level and lower levels can be performed until the
authentication is cleared.

♦
If a password is set for a button or other functional object, operation will not be possible
until the password is input, delaying operation. Therefore, do not set passwords for func-
tional objects that control machine operation.
Password Function
The password must be input before an operation on a password-protected functional object. An opera-
tion can be performed on a functional object only if the password is at the protection level set for that
functional object. The password must be input each time that an operation is performed on the func-
tional object.

Password Function (with level function)
When passwords with levels have been set, a password will be required the first time a pass-
word-protected functional object is manipulated. Inputting the password set for the functional object will
authenticate that password level, enabling manipulating functional objects in the same and lower levels.
Functional objects with higher-level passwords cannot be manipulated. Level 1 is the lowest level and
level 5 is the highest level.

Operations are enabled on functional objects
at the authenticated level and lower levels.
Operations are prohibited on functional
objects at a higher authentication level.
To manipulate functional objects with higher-level passwords, you must first cancel authentication.
Authentication can be canceled using the following methods.
• Authentication is canceled if the PT is restarted.
•
Authentication is canceled if the user presses a Command Button set to cancel authentication.
• Authentication is canceled if a specified timeout time elapses without performing an operation.
