Operations in the System Installer Mode Section 6-5
Change the system settings by following the menu operation from the System
Installer mode menu shown below.
• If Cancel is selected, the NT31/NT31C returns to the System Installer
mode menu without changing the settings. The settings remain as they
were before the operation was started.
• If writing of the settings fails, a screen asking whether you wish to try
again is displayed.
After the settings have been written, the System Installer mode menu screen
is redisplayed.
6-5-4 Clearing Screen Data
If the screen data has been corrupted and the NT31/NT31C cannot be started
normally, use this function to clear the screen data.
Note that only the screen data is cleared (initialized), and the memory switch
settings and the display history/alarm history record data are retained.
Reference: • When this function is used, all of the screen data contents registered in
the NT31/NT31C up to that point are cleared. Check that the created
screens are backed up at the Support Tool before using it.
• The screen data can also be cleared from the System Menu (page 140).
Select Change System Settings.
Select OK.
Select Display System Menu or Screen
Memory Protect.
Each time either of these items is selected,
the setting switches from Disabled to
Enabled or vice versa.
The settings are written to the NT31/NT31C
while the screen is displayed.
