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

Access to Variables in Arrays, Structures, and Blocks Access to array elements Syntax: <name of array variable> [  <comma-separated list of dimension indexes>  ] <name of array variable> Name of the a

Bit Access in Variables Important Implement concurrent bit access by two tasks only if the processor can execute bit access directly on the memory. All x86 and x64 systems have commands for bit access

Data Type: Implicit Enumeration The implicit enumeration allows for an easy way to declare a new enumeration variable which is valid only within the local POU. A variable of this type can take a limit

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: SIZEOF Tip In compiler version 3.5.16.0 and higher, the XSIZEOF operator should be used instead of this operator. The operator is an extension of the IEC 61131-3 standard. Syntax : <return v
