3.1 PRECAUTIONS TO BE OBSERVED WHEN USING THE
FOCAS1/Ethernet FUNCTIONS FOR THE FIRST TIME
CAUTION
When the Fast Ethernet board is used for the first
time, consult with your company’s network
administrator to determine the IP addresses and
other settings. Then, conduct a communications test.
If incorrect IP addresses and other settings are set,
communications may be interfered with or the entire
network might be adversely affected.
Particularly, if a duplicate IP address is set,
communication errors are caused intermittently. This
may result in a CNC's system error. To check
whether the IP address duplicates any one already in
use, see "Checking IP addresses for duplication" in
Appendix A.3, "Checking Communication."
