Part III FP Instructions
F273_DMIN
Minimum value search in 32-bit data table
Input s1 specifies the starting area of the data table, and s2 specifies the end. The minimum value
is returned at output min and its position at output pos.
The position pos is relative to the position at the beginning of the data table to the first occurrence
of the minimum value.
This instruction also exists as a P instruction (for FP2/2SH, FP3/5, FP10/10SH PLC types), which
is only executed at the rising edge of the EN trigger. Select [Insert P instruction] from the
"Instructions" pane if you require a P instruction. To facilitate reuse, the instruction then appears
under "Recently used" in the pop-up menu. Press <Ctrl>+<Shift>+<v> within the programming
area to open the list of recently used elements.
