Select this check box to send a notification when the ESC key is
used to exit the password input window after a change screen
operation initiated by the device/PLC.
This will not work when changing screens by touch.
Notification Bit Address
When you cancel a password input window displayed via the
Device/PLC control with the [ESC] key, the designated Notification
Bit Address turns ON.
In the System Settings workspace, [Display Unit] screen's
[Display] tab, if the [Reflect in Device/PLC] check box is cleared,
monitor the notification bit and when it turns ON, on the
device/PLC reset the [Change- to Screen] to the same number as the
[Current Screen]. When screen numbers match, the password input
window closes.
-

Device/PLC, please configure the System Data Area.
5.3.6 System
Settings [Display Unit] - [System Area] Settings Guide
-
When forced screen change is set up ([System
Area Start Address]+8, bit 15 is ON), input from the password input
window is canceled when the [Clear After Time Has Elapsed].
Although the Notification Bit Address turns ON, the password input
window continues to display.
Clear Security Level
This feature specifies whether to return the security level
status to "0", assuming no display unit operations/screen changes
are performed within the time specified in [Timer].
Timer
Specify the auto clear time from 1 to 60 minutes.
-
When using an internal device address bit
operation, setting bit 0 of LS9300 OFF→ON clears the security level
and resets the security level value in LS9301 to zero. After the
Security Level Clear occurs, return LS9300's 0 bit to OFF. (LS9301
is read-only)
Action on Screen Change
Once the security level becomes higher, the
current level will not be lowered unless it is automatically
cleared or cleared with the security control address (LS9300).
Therefore, you can change the screen as required.
When changing to a screen with a security
level lower than the current security level, the level is lowered
to the security level of the screen change.
Therefore, next time you switch the screen with lower security
level to the screen with higher security level, you will require
password authentication.
