The RX3i I/O Link Interface Module operates as a slave on a

Fanuc I/O Link network.  It can exchange either 32 or 64 inputs

and outputs with the master.  Typical masters on the I/O Link

include all modern FANUC CNCs and Power Mates,

PACSystems controllers and Series 90 PLCs equipped with an

I/O Link Master Module.

An I/O Link Interface Module occupies one module slot in an

RX3i backplane.  It can be installed in any available backplane slot.

The maximum number of I/O Link Interface Modules that can be

installed in the backplane depends on the power that is available

from the power supply.  To determine the exact number of

modules allowed in your system, see the information on power

supplies in chapter 3.

Usually, when there are multiple I/O Link Interface Modules in the

same RX3i system, they are on separate I/O Links.  However, it

is possible to have more than one I/O Link Interface Module in

the system connected to the same link, if that suits the needs of

the application.
