2 Instruction Descriptions
2-198
NJ-series Instructions Reference Manual (W502)
The following example is for when Size is UINT#3.
• Use the same data type for In1[], In2[], and AryOut[].
• If the subtraction results exceed the valid range of AryOut[], the elements of AryOut[] will contain ille-
gal values. An error will not occur. Corruption will not occur in the data in the memory area adjacent
to those elements.
• The values in AryOut[] do not change if the value of Size is 0.
• 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 AryOut[] will not change.
• In1[], In2[], and AryOut[] have different data types.
• The value of Size exceeds the array range of In1[], In2[], or AryOut[].
