b) Search result table

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, , +1, +2, +3

and +4,

are

occupied.

2)In the case of 32-bit operation

Ten

devices,

[

+1, ],

[

+3, +2],

[

+5, +4],

[

+7, +6]

and

[

+9,

+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].
