CAUTION
Before attaching or removing cables, power off the CNC
main unit, and confirm that the power is off.
Ask the respective manufacturers for explanations about
how to build a network and about conditions for using units
(such as a media converter, hub, transceiver, and cable)
other than the CNC unit. When installing network cables,
exercise sufficient caution so that the network will not be
affected by any noise source. Electrically separate the
network wiring sufficiently from noise sources like motors
and their power lines. Also, ground each unit as required.
If the grounding impedance is high, it may cause trouble in
communication. Once the equipment is installed, conduct
communication tests to verify normal operation before
starting actual use of the equipment.
FANUC is not liable to any damage related to trouble arising
from any unit other than the CNC unit.
(1)Connection to the Ethernet Interface
The 10BASE–T and 100BASE–TX interfaces are available. A hub
(line concentrator) is used to connect the CNC unit to a system. A
typical connection example is shown below.

Max. 100m
Some of the units (hub, transceiver, etc.) required to build a network
are not dust–proof. Using them in an atmosphere with dust or oil mist
may lead to a communication error or failure. They should be enclosed
in a dust–proof cabinet.
