Error code

Example

In the two examples below, if D2=K4 and D4=K8, or D2=K8 and D10 is always K4.

According to the source data sorted as follows, an example of the operation is shown below. In addition, by putting serial numbers such as management numbers in the first column in advance, the original row number can be judged based on the content, which is very convenient.

Press (N3)=K2 (column NO.2) to execute the sorting result (SM165=OFF in the case of ascending order)

Press (N3)=K3 (column NO.3) to execute the sorting result (SM165=ON in the case of ascending order)

✎Note:  Do not change the operand and data content during operation.

When executing again, the instruction input should be turned OFF once.

The SORT2 instruction can only be written twice in the program.

When the same device is specified in (S) and (D), the source data is rewritten to the sorted data order. Please pay special attention not to change the content of (S) before the end of execution.

Do not overlap the source data and the sorted data.
