(1) Searches in the n points of 32-bit BIN data, from the device designated by
maximum value and stores the searched maximum value at the device designated by

Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns ON, and
an error code is stored into SD0.

• The device specified by
(For the Universal model QCPU, LCPU.)
Program Example
(1) The following program subtracts, when X1C is turned ON, the data stored at D100 to D103
from the data stored at R0 to R3, and searches in the results of subtraction for the maximum
value, then, stores it at D200 to D202.
