Operand Specifications
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 IR0.

Output selection
0: Does not output address to IR00.
1: Outputs address to IR00.
Data type
0: Unsigned binary data
1: Signed binary data
The following table shows the possible values of C.

C000 Signed binary
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
C.)
