2 Instruction Descriptions
2-104
NJ-series Instructions Reference Manual (W502)
The following example is for when In is INT#120 and Size is UINT#3.
• Use the same data type for In and Table[]. Otherwise, a compiling error will occur.
• Use a two-dimensional array for Ta bl e [] . A compiling error will occur if you use any other size of array.
• If an array with more than two dimensions is used for Ta bl e [] , the elements in the third and higher
dimensions are ignored.
• If the AryOut[] array is larger than the value of Size, the comparison results will be stored in AryOut[0]
to AryOut[Size
−
1]. Other elements of the array will not change.
• Signed integers (SINT, INT, DINT, and LINT) cannot be compared to unsigned integers (USINT, UINT,
UDINT, and ULINT).
• If real numbers are compared, error may cause unexpected processing results. This can occur, for
example, when they contain non-terminating decimal numbers.
• If the value of Size is 0, the value of Out will be FALSE and AryOut[] will not change.
• If this instruction is used in a ladder diagram, the value of Out changes to FALSE if an error occurs in
the previous instruction on the rung.
• An error occurs in the following cases. Out will be FALSE.
• If the value of Size exceeds the size of the AryOut[] array.
• If the value of Size exceeds the size of the first dimension of the Ta ble[] array.
• The size of the second dimension of Tabl e [ ] is 1.
