C and C+1: Control words
C specifies the number of words in the range, bit 15 of C+1 indicates whether
the data will be treated as signed binary or unsigned binary, and bit 14 of C+1
indicates whether or not to output the PLC memory address of the word that
contains the maximum value to IR00.
Note C and C+1 must be in the same data area.

R1: First word in range
R1 specifies the first word in the search range. The words from R1 to R1+(C–
1) are searched for the maximum value. (C is the number of words specified in
