Security and Passwords
Parameter values can be password-protected using the OIM. When the password
is enabled, parameter values can be displayed. However, if there is an attempt to
change a parameter value, a password pop-up box appears on the OIM screen to
prompt for the user-defined write-protect password.
To set the write-protect password, select the Password icon from the main menu.
See
Figure 29 . The password value can range from 1...9999. A value of 0 disables

correct value and then set the password to zero.
When the password is enabled, the lock symbol on the screen changes from

Figure 29 - Setting the Write-protect Password
When you enter the password, you can adjust parameters until you select Logout
or return to the process display screen, which re-activates the password. See
Monitoring the Drive Using the Process Display Screen on the OIM on page 238
for information about the process display screen.
ATTENTION: It is your responsibility to determine how to distribute the write-
protect password. Rockwell Automation is not responsible for unauthorized
access violations within your organization. Failure to observe this precaution
could result in bodily injury.
IMPORTANT This option is not supported in the VS Utilities software.
