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

(G, IN0, IN1) means: OUT := IN0; if G = [...] Permitted data types IN0

0 THEN // 0 means [...] on the string dwSynch := 0

Operator: __POUNAME The operator is an extension of the IEC 61131-1 standard. At runtime, the operator yields the name of the POU that contains the operator __POUNAME . The result is of type STRING .

. <partial index> From 0 [...] PartialVarB := GVL.Variable.%B0; PartialVarX := array[idx].%X0

Functions In ST, you can use a function call as an operand. Example 194 . Example: Result := Fct(7) + 3; TIME() function This function yields the time (in milliseconds) that has elapsed since system b

Data Types In the programming, a variable is identified by its name and has an address in the memory of the target system. Accordingly, variable names are identifiers under which the allocated memory
