When bit 15 of C+1 has been set to 1, the data within the range is treated as
signed binary data and hexadecimal values 8000 to FFFF are considered
negative. Thus, the results of the search will differ depending on the data-type
setting.
When CIO 000000 turns ON in the following example, MAX(182) searches
the 10-word range beginning at D00200 for the maximum value. The maxi-
mum value is written to D00300 and the PLC memory address of the word
containing the maximum value is written to IR00.
