7.5 Data processing instructions
7.5.11 Minimum value search for 16- and 32-bit data (MIN(P),DMIN(P))
DMIN
(1) Searches in the n points of 32-bit BIN data, from the device designated by , for the
minimum value and stores searched minimum value at the devices designated by and
+1.
Starts the search from the device designated by and stores the location, specified in the
number of points counted from , of the device where the minimum value is found first at
+2 and stores the number of the found minimum values at +3.
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 n-bit range from the device specified by exceeds the range of the corresponding
device. (Error code: 4101)
• The device specified by exceeds the range of the corresponding device.
(For the Universal model QCPU only.) (Error code: 4101)
Program Example
(1) The following program adds, when X1C is turned ON, the data stored at D100 to D103 and
the data stored at R0 to R3, and searches in the results of addition for the minimum value,
then, stores it at D200 to D202.
