6-5-4 Clearing Screen Data

If the screen data has been corrupted and the NT631/NT631C 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 NT631/NT631C 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 135).
