Function
The number of records specified by C starting from the record specified by S are sorted according to
the data in the specified location (1 word). When the sort operation has been completed, the Carry Flag
will turn OFF and the number of records that were sorted will be output to D1. If outputting to an index
register is specified in C+4, one address higher than the PLC memory address of the last word in the
sorted records is output to the specified index register. The sort direction is specified as ascending or
descending in C+3.
If split sorting is enabled in C+3, the sort will be executed over multiple cycles. The Carry Flag will be
ON while the sort operation is being executed and will turn OFF when the sort operation has been
completed. If the execution condition of RSORT turns OFF before the sort operation has been finished,
the sort will be continued the next time the execution condition turns ON.
