Function operation:
The POWER function returns as a result the input value raised to the power of a. This exponent is set during the creation of the function block and can only be a natural number in the range 1 to 255. If the result is greater than the upper value of a real type variable (-1, 7 * 10E308 ... 1.7 * 10E308), the limit output is activated, and the OUT output is the maximum value of a real type variable.
