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: SIN The IEC operator yields the sine value of a number. Permitted data types for input variables that measure the angle in radians: any numeric basic data type Permitted data types for outpu

Operator: SEL The IEC operator is used for bitwise selection. OUT := SEL(G, IN0, IN1) means: OUT := IN0; if G = FALSE OUT := IN1; if G = TRUE Permitted data types IN0 , …, INn and OUT : any identical

Operator: MAX The IEC operator is used for the maximum function. It yields the greatest value of all inputs. OUT := MAX(IN0,IN1,IN2,...) Permitted data types: all Example 110 . Examples Result: 90 ST

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

Operator: MUX The IEC operator is used as a multiplexer. OUT := MUX(K, IN0,...,INn) That means: OUT = IN_K Permitted data types for K : BYTE , WORD , DWORD , LWORD , SINT , USINT , INT , UINT , DINT ,

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
