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

Operator: NE The IEC operator compares two operands for inequality. All elementary data types are permitted as data types for the operands. If the operands are unequal, then the operator yields the re

Operator: Content Operator The operator is an extension of the IEC 61131-3 standard. The operator allows for dereferencing a pointer. You append the operator as ^ to the pointer identifier. Caution Wh

Overloading Important If the operand value for a type conversion operator is outside of the value range of the target data type, then the result output depends on the processor type and is therefore u

Operator: MOD The IEC operator is used for modulo division. The result of the function is the non-negative, integer remainder of division. Permitted data types: BYTE , WORD , DWORD , LWORD , SINT , US
