Example 2
Parameter 480 is a type long double word (P[I]-D), is data set switchable and is
to be written. The target data set is Data set 3.
Reference value = -300.00 Hz (-30000 is transmitted)
According to integer arithmetics, the negative value is represented as follows:
0xFFFF8AD0
34 CM-PROFINET 10/13
