The function calculates the sine of BCD code angular data (input s) and stores the result (output d)

as a BCD value in an array with three elements.

BCD values for input s lie in the area from 0° to 360° (16#0 to 16#360) in 1° steps. With this, output

d can yield a result in the range of -1.0000 to 1.0000. The result is returned as follows:

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.

using IL (instruction list), please refer to the online help. In addition, an analytical program is

created that interprets the result. The same POU header is used for both programming languages.
