Why is "**" or "***" displayed in the numeral display on my Omron Touch terminal?
- M
  Maria HoffmanAug 31, 2025
  "**" or "***" is displayed in the numeral display or numeral input field because the numeric value in the numeral memory table exceeds the number of display digits. Check the values of the PLC words allocated to the numeral memory table entry. Allocate only one word to each numeral memory table entry if the numeral display or numeral input field has 4 digits or less.

  The digits in the numeral display come out as asterisks because the number of digits of a numeric value in a numeral memory table exceeds the set number. Confirm the values of the PLC words allocated to the numeral memory table. Allocate one PLC word to each numeral memory table.
