Initialization of the random generator FB_RandomGenerator
As the generation of the random numbers is effected in accordance with the linear congruence method, a start value i_diNstart is required which is set by means of the Init method. This can be any integer > 0 which is located within the value range of data type DINT.
This method must have been called up once before calling up the GetDint or GetLreal methods.
