SNMP Trap
When specific conditions occur, the built-in EtherNet/IP port that is set as the SNMP agent sends sta-
tus notification reports to the SNMP manager
.
The SNMP manager can learn about changes in status even without periodically monitoring the built-
in EtherNet/IP port.
Status notification reports are sent under the following conditions.
• When the Controller is turned ON
• When links are established
• When an SNMP agent fails to be authorized

TCP/UDP Message Service
This function supports TCP/UDP socket communications, which allow simple access to CIP objects of
the Controller from a system where EtherNet/IP is not supported. This will allow you to change settings
and perform I/O control for NX Units connected to the Controller or the NX bus.
Y
ou can use the TCP/UDP message service only for the NX102 CPU Units.
