The PT starts with authentication canceled. When the PT starts, it does not display the specified
screen specified after authentication is canceled; it displays the initial screen specified on the
System Setting Dialog Box’s Initial Tab Page.
Using Passwords with Levels
Passwords with level can be used to display screen suitable to the operation to prevent inappropriate
operation, including operating errors. The level authentication screen can be displayed as the startup
screen. Command buttons on this screen can be used, for example, to provide separate authentication
levels for operators vs. managers. The screen can be switched depending on the level that is authenti-
cated.
A level would be set for each command buttons, for example level 1 for operators and level 5 for man-
agers. All screens displayed after authentication (e.g., device operation monitoring screens and main-
tenance screens) would contain a command button to cancel authentication. The password settings
would specify that the authentication screen be displayed when authentication is canceled.
1. An operator or manager would press the command button set for them on the authentication
screen and then enter the password in the password input dialog box to authenticate the appropri-
ate level.
2. If the level is authenticated, either the operator’s screen or the manager’s screen would be dis-
played. These screens would be user application screen for device operation monitoring, mainte-
nance, etc.
3. When work was completed and the PT left, the command button to cancel authentication would be
pressed, switching the display back to the authentication screen. (It is possible to switch to any
specified screen after authentication is canceled.)
