The C200H I/O Link Unit is a Special I/O Slave Unit that allows data from any
area in the CPU Unit of the PLC to be read or written from the Master Unit.
Using the C200H I/O Link Unit, a Slave PLC can be controlled by the Master
through the DeviceNet Network.
Memory areas being used by other Special I/O Units can also be specified,
allowing Special I/O Units mounted to the Slave PLCs to also be controlled
indirectly from the Master.
Wire communications cables to the C200H I/O Link Unit using the standard
Square Connectors, just like General-purpose Slaves. This section does not
explain how to connect communications cables. For details on connecting the
cables, refer to 4-2 Connecting Communications Cables to General-purpose
Slaves .
The DIP switch on the rear panel of the Unit is used to set the node address
for the C200H I/O Link Unit.
The node address is set with pins 1 through 6 of the DIP switch, as shown in
the following table. Any node address within the setting range can be used as
long as it isn't already set on another node.

Any node address within the setting range can be used as long as it is not
already set on another node in the network.
1. (Refer to Appendix A Node Address Settings Table for a complete table of
DIP switch and baud rate settings.)
2. The default setting is 0. Because the node address setting for the C200H
I/O Link Unit is made on the rear panel DIP switch, the Unit must be re-
moved before the setting can be changed. For this reason, be sure the set-
ting is correct before configuring the network.
3. Pins 7 and 8 are reserved for system use. They must always be set to OFF.
4. If the same node address is used for two different nodes, a node duplica-
tion error will occur.
