As the two interfaces above show, the starting addresses of the INPUT and OUTPUT areas that

AH PLC assigns to the master module are D1000 and D6000 respectively. On the above interface,

the input offset address for 4 word input is 0 and the corresponding starting number of D registers

in the master PLC is 1000（1000=1000+0/2）. The input offset address for 2 word input is 8 and

the corresponding starting number of D registers in the master PLC is 1004（1004=1000+8/2）.

The output offset address for 4 word output is 0 and the corresponding starting number of D

registers in the master PLC is 6000（6000=6000+0/2）; the output offset address for 2 word

output is 8 and the corresponding starting number of D registers in the master PLC is 6004

（6004=6000+8/2）.
