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 set- tings and the display history/alarm history record data are retained.

Reference: S 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.

SThe screen data can also be cleared from the System Menu (page 140).

SIf the screen data is cleared in the System Installer mode, the message Screen Data Corrupted may be displayed on switching to the RUN mode. If this hap- pens, initialize the screen data again from the MEMORY INIT. MENU screen.

Clear the screen data by following the menu operation from the System Installer mode menu shown below.

Select Erase Screen Data.

Select Yes.

The screen data is cleared. During clear- ance, the message Erasing ... is displayed.

•If Return to Menu is selected, the NT31/NT31C returns to the MEMORY INIT. MENU screen without clearing the screen data.

•If screen data clearance fails, a screen asking if you wish to try again is dis- played.

On completion of screen data clearance, the NT31/NT31C returns to the Sys- tem Installer mode menu screen.

After the screen data has been cleared, if an attempt is made to set the NT31/NT31C to the RUN mode before screen data has been transmitted from the Support Tool or memory unit, an error message will be displayed and the RUN mode will not be established.
