The following example is for when Size is UINT#2.
• Use the MOVE instruction (page 2-318) to assign constants to variables.
• Use the MemCopy instruction (page 2-327) to copy the values of variables to other variables.
• Use the same data type for the elements of InOut1[] and InOut2[]. If they are different, a building error
will occur.
• If the value of Size is 0, the value of Out will be TRUE and InOut1[] and InOut2[] will not change.
• Return value Out is not used when the instruction is used in ST.
• An error occurs in the following cases. ENO will be FALSE, and InOut1[] and InOut2[] will not change.
• The value of Size exceeds the array range of InOut1[] or InOut2[].
• InOut1[] and InOut2[] are STRING arrays and there is an element with a text string that exceeds
the size of the element in the other array.
• InOut1[] and InOut2[] are STRING arrays and there is an element that does not end in a NULL
