Figure 14-8. General Operation Screen, CT & VT Setup Tab
Global Security
Each of three communication ports and the three functional areas (Settings, Reports, and Control) has
password security access. This allows the user to customize password protection for any and all ports.
See
Figure 14-9. For example, you could allow technicians to have Global Access (sometimes called a
fourth level of access) to all three functional areas via the front port. You could also restrict the rear port,
which is connected to a modem to read-only access.
If you select Show Passwords and the default passwords have not been changed, all four passwords
appear and can be changed. If the Global Access password has been changed, a dialog box appears
explaining that you must enter the global password to enable viewing and editing the existing passwords.
After entering the global password, the passwords and enable boxes appear. You may then make
changes in any and all areas. Clicking a box for a specific communication port toggles the functional area
for that port either ON or OFF. Notice that the front panel HMI and communications port zero are
combined and considered as one.
