Level 0 to Level 15

For Logic Function, GP-Viewer Function, and FTP Function, you can set the security level between 0 to 15. However, the following standards for the level settings apply depending on each function.

• Logic Monitor and Online Logic Editing

Only a constant level, or a high Online Logic Editing level, can be set.

You can only set the normal level or a level higher than that set up for Write GP-Viewer Data.

You can only set the normal level or a level higher than that set up for Save or delete files in FTP folder.

Enable Notification Bit

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.

From [Project] menu, point to [System Settings] and click [Display Unit] to open the dialog box and click [Display Settings] tab. If [Reflect in Device/PLC] is not selected, monitor the notification bit. If 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.

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.

Action on Screen Change

• Record Security Level

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.

• Input Password When Level Increases

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.
