Operator: AND_THEN The operator is an extension of the IEC 61131-3 standard. The AND_THEN operator is permitted only for programming in structured text with the AND operation of BOOL and BIT operands

Operator: OR_ELSE The operator is an extension of the IEC 61131-3 standard. The OR_ELSE operator is permitted only for programming in structured text: OR operation of BOOL and BIT operands with short-

Operator: SHL The IEC operator is used for bitwise shift of an operand to the left. erg := SHL (in, n) in : Operand which is shifted to the left n : Number of bits to shift in to the left Important If

Operator: SHR The IEC operator is used for bitwise shift of an operand to the right. erg := SHR (in, n) in : Operand which is shifted to the right n : Number of bits to shift in to the right Important

Operator: ROL The IEC operator is used for bitwise rotation of an operand to the left. Permitted data types: BYTE , WORD , DWORD , LWORD erg := ROL (in, n) CODESYS moves in n-times one bit to the left

Operator: ROR The IEC operator is used for bitwise rotation of an operand to the right. Permitted data types: BYTE , WORD , DWORD , LWORD erg := ROR(in,n) CODESYS moves in n-times one bit to the right

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

Operator: CAL The IEC operator is used for calling function blocks. In IL, CAL calls the instance of a function block. CAL <function block> (<input variable1> := <value>, <input variableN> := <value>)

Operator: ABS The IEC operator yields the absolute value of a number. Permitted data types for input and output variables and numeric constants: any numeric basic data type Example 123 . Examples Resu

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
