There are two types of node on a CompoNet Network: The slaves and a Com-
poNet Master Unit. The slaves connect to external I/O. The Master Unit con-
trols the CompoNet Network and sends I/O data between the PLC and the
slaves.
A SmartSlice I/O Terminal is a slave on a CompoNet Network. You must set a
node address for it.
You can use the node address to find the first word that is allocated to the
SmartSlice I/O Terminal.
The SmartSlice I/O Terminal is a Word Slave.

CompoNet Communications Unit.
2. Set the 10s digit of the node address on the left rotary switch and set the
1s digit on the right rotary switch.
Set the node address to between 0 and 63. Do not set the same address
for more than one node (nodes for CompoNet Master Unit and slaves).

3. Turn ON the power supplies.
If you set a node address that is the same as a different node, the NS indica-
tor on the CompoNet Communications Unit will come ON in red. A network
configuration error will occur and normal communications will not be possible.
