Operator: MIN The IEC operator is used for the minimum function. It yields the least value of all inputs. OUT := MIN(IN0,IN1,IN2,...) Permitted data types: all Example 111 . Examples Result: 30 ST Var

Operator: LIMIT The IEC selection operator is used for limiting. OUT := LIMIT(Min, IN, Max) That means: OUT := MIN (MAX (IN, Min), Max) Max is the upper limit and Min is the lower limit for the result
