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

Operator: MOVE The IEC operator is used for assigning a variable to another variable of a corresponding type. Because MOVE is available in the CFC, FBD, and LD editors, you can also use the EN/ENO fun

Operator: INDEXOF The operator is an extension of the IEC 61131-3 standard. Instead of the INDEXOF operator, the ADR operator is provided in CODESYS V3 for getting a pointer at the index of a POU. :

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
