Allocation of the Mapping Addresses for AHRTU-DNET-5A

The input and output mapping starting addresses of AHRTU-DNET-5A are allocated automatically
by the master when it is added to the master. And the AH10DNET-5A master will allocate the
mapping address to AHRTU-DNET-5A according to the lengths of the input and output mapping
addresses of AHRTU-DNET-5A. The lengths of the input and output mapping addresses are
determined by the configuration parameters of the modules connected to AHRTU-DNET-5A. The
mapping starting addresses will be allocated to AHRTU-DNET-5A only when it is added to the
master and meanwhile they are related with the sequence in which the slave is added to the master.
When the two slaves DT01S and AHRTU-DNET-5A exist simultaneously, the lengths of input and
output mapping addresses of AHRTU-DNET-5A are both 80 bytes; those of DT01S are both 4 bytes;
the input and output mapping starting addresses of AH10DNET-5A are specified as D1000 and
D2000 as below. If DTO1S is added to the master prior to AHRTU-DNET-5A, the input and output
mapping addresses of AHRTU-DNET-5A are D1007~D1046 and D2007~D2046 respectively and
D1007 and D2007 are its input and output mapping starting addresses respectively.
