The function calculates the cosine 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.
