5.5 Linking The EMBEDDED Ethernet Interface
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.
5.5.1 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.
