Constant: Typed Literal With the ecxeption of REAL or LREAL -Constants (in this case, always LREAL is used) the smallest possible data type is used when calculating with IEC constants. If you want to

Operator: MUL The IEC operator is used to multiply variables. Permitted data types: BYTE , WORD , DWORD , LWORD , SINT , USINT , INT , UINT , DINT , UDINT , LINT , ULINT , REAL , LREAL , TIME Feature

Operator: SUB The IEC operator subtracts variables. Permitted data types: BYTE , WORD , DWORD , LWORD , SINT , USINT , INT , UINT , DINT , UDINT , LINT , ULINT , REAL , LREAL , TIME , LTIME , TIME_OF_

Operator: DIV The IEC operator is used to divide variables. Permitted data types: BYTE , WORD , DWORD , LWORD , SINT , USINT , INT , UINT , DINT , UDINT , LINT , ULINT , REAL , LREAL , TIME Important

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
