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.
Instead of using this FP instruction, we recommend using the related IEC instruction SQRT (see
page 68). Please refer also to Advantages of the IEC instructions in the online help.

Variable Data type Function
s DINT, DWORD source, 32-bit area to be calculated
d DINT, DWORD square root (decimal places deleted)
The variables s1 and d have to be of the same data type.
For Relay T/C Register Constant
s DWX DWY DWR DWL DSV DEV DDT DLD DFL dec. or hex.
d - DWY DWR DWL DSV DEV DDT DLD DFL -
Description
The square root of the 32-bit data or constant value specified by s is calculated if the trigger EN is
in the ON-state. The result (square root) is stored in d.
