MAX(182) searches the range of memory from R1 to R1+C–1 for the maxi-
mum value in the range and outputs that maximum value to D.
When bit 14 of C+1 has been set to 1, MAX(182) writes the PLC memory
address of the word containing the maximum value to IR00. (If two or more
words within the range contain the maximum value, the address of the first
word containing the maximum value is written to IR00.)
When bit 15 of C+1 has been set to 1, MAX(182) treats the data within the
range as signed binary data.
R1+(W–1)
Note MAX(182) can be processed in the background. Refer to the SYSMAC CS/
CJ/NSJ Series PLC Programming Manual (W394) for details.

A595 and When an index register is specified as the out-
A596 put for an instruction processed in the back-
ground, A595 and A596 receive the output
instead of IR00.
(A595 contains the rightmost digits, and A596
contains the leftmost digits.)
