| Default Limit TypeAbsolute 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.
