Operator: SQRT The IEC operator yields the square root of a number. Permitted data types for input variables: any numeric basic data type Permitted data types for output variables: REAL and LREAL Exam

Operator: LN The IEC operator yields the natural logarithm of a number. Permitted data types for input variables: any numeric basic data type Permitted data types for output variables: REAL and LREAL

Operator: EXP The IEC operator yields the exponential function. Permitted data types for input variables: any numeric basic data type Permitted data types for output variables: REAL and LREAL Example

Operator: EXPT The IEC operator raises a number to a higher power and returns the power of the base raised to the exponent: power = base exponent . The input values (parameters) are the base and the e

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

Operator: GT The IEC operator is used for the "greater than" function. Permitted data types of the operands: any basic data type If the first operand is greater than the second operand, then the opera

Operator: LT The IEC operator is used for the "less than" function. Permitted data types of the operands: any basic data type If the first operand is less than the second operand, then the operator yi

Operator: LE The IEC operator is used for the "less than or equal to" function. Permitted data types of the operands: any basic data type If the first operand is less than or equal to the second opera

Operator: GE The IEC operator is used for the "greater than or equal to" function. Permitted data types of the operands: any basic data type If the first operand is greater than or equal to the second

Operator: EQ The IEC operator compares two operands for equality. All elementary data types are permitted as data types for the operands. If the operands are equal, then the operator yields the result
