same.
NOTE You do not need to enter a password to go online. However, if
the selected program on disk is protected, you must enter a password to
go offline.
A password value consists of 1 to 8 alphanumeric digits (for example, 0-
9 or uppercase A-Z). Online, you can be prompted for the password for
the controller program and/or for the selected program on disk. Offline,
you are prompted for a password only for the selected program on disk.
The selected program on disk may be in one of two states of password
protection:
•
No Password: The selected program on disk is not protected.
Any authorized user may enter an initial password.
•
Disabled Password: The selected program on disk is not
protected. Any authorized user may change or delete the
password.
The programmable controller may be in one of three states of password
protection:
•
No Password: The controller program is not protected. Any
authorized user may enter an initial password.
•
Disabled Password: The controller program is not protected.
The user may change or delete the password. Any authorized
user may enable the password.
•
Enabled Password: The controller program is protected
according to the protection level assigned to the password
(see below). If a protected operation is attempted from any
communications port, the operation is denied and an error
response is given. Only an authorized user may change,
delete, or disable the password.
Three levels of access are available when a password has been entered
and enabled in the controller:
•
No Access: The controller program cannot be read or
modified.
•
Read-only Access: The controller program can be read but it
cannot be modified.
•
Full Access: The controller program is not protected.
