CIP Safety on EtherNet/IP Compatible
Combined with the NX-SL5£££ Safety Control Unit, you can build a system which uses CIP
Safety on EtherNet/IP communications in networks between Controllers and field networks. Safety
communications by CIP Safety is enabled with devices that support CIP Safety on EtherNet/IP and
other Safety CPU Units.
Precautions for Correct Use
• An NX-series EtherNet/IP Unit is required to perform CIP Safety communications. The built-in
EtherNet/IP port on an NX502 CPU Unit does not support the CIP Safety communications.
• CIP Safety communications and tag data links cannot be used together in one NX-series
EtherNet/IP Unit.
•
The I/O refresh time varies depending on the number of connections for CIP Safety commu-
nications. Check the effect of the number of connections for CIP Safety communications on
the task execution time.

LLDP
The LLDP (Link Layer Discovery Protocol) enables to exchange information with other network de-
vices that are connected to a physically communicable range.
