DeviceNet I/O Link Units
Section 7-7
Connecting the DeviceNet
I/O Link Unit
DeviceNet I/O Link Units are connected to the CP1H CPU Unit. Up to seven
Units can be connected, including any other Expansion Units and Expansion
I/O Units that are also connected. The Units can be connected in any order
from the CPU Unit.
I/O Allocation
I/O words are allocated to the DeviceNet I/O Link Unit in the same way as to
Expansion I/O Units or other Expansion Units, i.e., the next available input
and output words are allocated. As shown below, when “m” is the last allo-
cated input word and “n” is the last allocated output word, the DeviceNet I/O
Link Unit is allocated “m+1” as its input word and “n+1” as its output word.
In the following example, a CompoBus/S I/O Link Unit is connected as the first
Unit after the CP1H CPU Unit.
All of the words allocated to the DeviceNet I/O Link Unit are used to read and
write data between the CPU Unit of the DeviceNet I/O Link Unit and the CPU
Unit of the DeviceNet master, as shown in the following illustration.
