limit

 

This function block compares the value applied to the input IN with the values applied to the inputs MN ( MINIMUM VALUE ) and MX ( MAXIMUM VALUE ). If the input value is less than the value applied to the MN input then the output reports the value of MN pin. If the input value is greater than the value applied to the MX input then the output gives the value applied to the MX pin. When the value applied to the input is inside the two limits the value is transferred to the output without limitations.
