When a file named
.csipasswd
is stored on the data logger CPU drive, basic access
authentication is enabled in the data logger and read/write access to the web interface can be
defined. Multiple user accounts with differing levels of access can be defined for one data
logger. Four levels of access are available:
l
None: Disable a user account.
l
Read Only: Data collection is unrestricted. Clock and writable variables cannot be changed.
Programs cannot be viewed, stopped, deleted, or retrieved.
l
Read/Write: Data collection is unrestricted. Clock and writable variables can be changed.
Programs cannot be viewed, stopped, deleted, or retrieved.
l
All: Data collection is unrestricted. Clock and writable variables can be changed. Programs
can be viewed, stopped, deleted and retrieved.
NOTE:
All levels of access allow data collection.
Create an encrypted password file or modify an existing password file using Device Configuration
Utility:
1. Connect to your device in Device Configuration Utility.
2. Click the Network Services tab, then the Edit .csipasswd File button.
3. Define user accounts and access levels.
4. Click Apply. The
.csipasswd
file is automatically saved to the data logger CPU drive.
When a
.csipasswd
file is used, the PakBus/TCP Password security setting is not used when
accessing the data logger via HTTP. If the
.csipasswd
file is blank or does not exist, the
default user name is "anonymous" with no password and a user level of read only.
When access to the data logger web server is attempted without the appropriate security level,
the data logger will prompt the web client to display a username and password request dialog. If
an invalid username or password is entered, the data logger web server will default to the level of
access assigned to “anonymous”. As noted previously, anonymous is assigned a user level of
read-only, though this can be changed using Device Configuration Utility.
If the numeric security code has been enabled, and no
.csipasswd
file is on the data logger,
then that numeric security code must be entered to access the data logger. If a
.csipasswd
file is on the data logger, the username and password employed by the basic access
authentication will eliminate the need for entering the numeric security code.
