19.7 FNC149 – SORT2 / Sort Tabulated Data 2
The data table configuration is explained in an example in which the sorting source data table has 3 lines and
4 columns (m1 = K3, m2 = K4). For the sorting result data table, understand as .
• Set the sorting order by setting M8165 to ON or OFF.
• When the command input turns ON, data sorting is started. Data sorting is completed after "m1" scans,
and the instruction execution complete flag M8029 is set to ON.
→ For the instruction execution complete flag use method, refer to Subsection 6.5.2.
2. 32-bit operation (DSORT2)
In the data table (sorting source) having (m1 × m2) points from [ +1, ], data lines are sorted in the
ascending or descending order based on the group data in the column No. "n", and the result is stored in the
data table (sorting result) having (m1 × m2) points from [ +1, ].
→ For operation examples, refer to Page 523.
The data table configuration is explained in an example in which the sorting source data table has 3 lines and
4 columns (m1 = K3, m2 = K4). For the sorting result data table, understand as .
• Set the sorting order by setting M8165 to ON or OFF.
• When a data register D or extension register (R) is used for "m1", the data length is 32 bits.
For example, when "m1" is specified in D0, "m1" is 32-bit data stored in [D1, D0].
• When the command input turns ON, data sorting is started. Data sorting is completed after "m1" scans,
and the instruction execution complete flag M8029 is set to ON.
→ For the instruction execution complete flag use method, refer to Subsection 6.5.2.
