Cautions
• Comparison of values
It is executed algebraically.
(example: −10 < 2)
• When there are two or more maximum or minimum values
When there are two or more maximum or minimum values in the searched data, the last position of the max/min is
stored respectively.
• Number of occupied devices
When this instruction is driven, the following number of devices are occupied for storing the search result
Make sure that such devices are not used in other controls for the machine.
1)In the case of 16-bit operation
Five devices,
2)In the case of 32-bit operation
Ten devices, [
D D
+8], are occupied.

• Note that the 32-bit value [n+1, n] is valid when D or R is specified as "n" in a 32-bit instruction.
In the case of "DSER D0 D100 D200 R0", "n" is [R1, R0].
