1.3 Login Function
Explanation of user privileges
• Operations performed using communication commands are also limited. However,
operations can always be performed through Modbus communication, regardless of
the settings.
See section 3.2 in the Communication Manual
• Operations assigned by the event action function are always performed, regardless of
the operation-limitation settings.
• Even if you lock computation, if the starting and resetting of computation are enabled
for the START key operation, computation is reset or started when recording starts.
• Even if you enable USER key operations, if you assign an operation that is locked to
the USER key, that operation will not be performed when you press the USER key.
• If you lock the DISP/ENTER key, you will not be able to show display selection menus.
DISP/ENTER key execution operations and DISP/ENTER key operations in setting
mode are not locked.
• The operations that you can perform vary as shown in the table below depending on
how you set the free/locked settings of Calibration and the MENU key (the operation
to enter into setting mode).
MENU Key Calibration
Locked Free
Locked You cannot perform any setting
mode settings.
You can only perform calibration
correction.
Free You can perform all setting mode
settings except for measurement-
channel input-range settings and
calibration-correction settings.
You can perform all setting mode
settings.
User ID
You can choose whether or not to use a user ID.
User ID and Password
You cannot specify a user-ID and password pair that is already registered on the DX.
Period of Password Validity
You can set the period of password validity (but not for Web-server users).
Number of Password Retries and User Invalidation
When a user is prompted for a password, if he or she enters the wrong password
consecutively for the specified number of times (password retry frequency), the user’s
account is invalidated, and the user cannot log in (Web-server users are not affected).
An administrator can clear the “invalid user” status by setting the invalidated user’s
password to the default password.
Reusing User-Registration Settings
The user-registration settings are stored in setup data files. If you want to use the user-
registration settings of one DX on another DX, you can load just the user-registration
settings from the setup-data file. However, the passwords are not loaded. All the
administrator and user passwords are set to their defaults.
For operating instructions, see section 6.9 in the User’s Manual.
