  • Absolute

    The upper and lower deviation of the target value is expressed as an absolute value.

    • Limit

      If the upper limit is expressed as an absolute value, the value is defined to which the process variable's target value can be exceeded.

      For example, if the norm is 30 and the upper limit must not exceed 33, 33 is displayed this field.

    • Percentage
  • Percentage

    The upper and lower deviation of the target value is determined by a percentage.

    • Limit

      If the upper limit is expressed as a percentage, the percentage is defined with which the process variable's target value can be exceeded.

      For example, if the norm is 30 and the upper limit must not exceed 33, 10% is displayed in this field.

    • Percentage

      If the lower limit is expressed as a percentage, the percentage is defined that the process variable's input value can be lower than the norm.

      For example, if the norm is 30, and the lower control limit must not be lower than 27, 10% is entered in this field.
