Function
z MAX
MAX(182) searches the range of memory
from R1 to R1+(W-1) for the maximum 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
IR0. (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 IR0.)
When bit 15 of C+1 has been set to 1,
MAX(182) treats the data within the range as
signed binary data.
z MIN
MIN(183) searches the range of memory
from R1 to R1+(W-1) for the minimum value
in the range and outputs that minimum value
to D.
When bit 14 of C+1 has been set to 1,
MIN(183) writes the PLC memory address of
the word containing the minimum value to
IR0. (If two or more words within the range
contain the minimum value, the address of
the first word containing the minimum value is
written to IR0.)
When bit 15 of C+1 has been set to 1,
MIN(183) treats the data within the range as
signed binary data.

IR0 Output for Background
Execution
A595 and A596 When an index register is specified as the output for an instruction processed in the background, A595
and A596 receive the output instead of IR0.
(A595 contains the rightmost digits, and A596 contains the leftmost digits.)
