If AHRTU-DNET-5A is added to the master prior to DT01S, the input and output mapping addresses 
of AHRTU-DNET-5A are D1005~D1044 and D2005~D2044 respectively and D1005 and D2005 are 
its input and output mapping starting addresses respectively. 
When AHRTU-DNET-5A is added to the master, its input and output mapping starting addresses are 
fixed and defined as the status word and control word of AHRTU-DNET-5A respectively as below. 
The registers after the input and output mapping starting addresses are used for mapping the 
configuration parameters of the I/O module.
