Example 2
Parameter 480 is a double word (P[I]-D), long, data set change-over capable, and is to be written.
The target data set is data set 3.
Reference value = -300.00 Hz (-30000 is transmitted)
The negative value is portrayed as follows in accordance with integer arithmetic: 0xFFFF8AD0
Request from Master:
AK = 8 (request identification = write parameter value long Array)
PNU = 480 (= 0x1E0)
IND = 3
PWEh = 0xFFFF
PWEl = 0x8AD0
