NJ-series Instructions Reference Manual (W502)
The AryToBCD instruction converts Size elements of unsigned integer array In[] starting from In[0] to
a BCD bit string. It outputs the BCD bit string to BCD array AryOut[].
The following example is for when Size is UINT#3.
The following table shows the valid ranges for In[] and AryOut[] according to the data types of their
elements.
• Use the same data type and size for In[] and AryOut[]. For example, if the elements of In[] are UINT
data, use WORD as the data type of the elements of AryOut[].
• This instruction does not convert signed binary to signed BCD. Use an unsigned integer (USINT,
UINT, UDINT, or ULINT) as the data type of In[].
• 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.
• The value of In[] is outside of the valid range.
• The data type sizes of In[] and AryOut[] are different.
• The value of Size exceeds the array area of In[] or AryOut[].
