9-8 TCP/UDP Message Service
9-8-1 Outline of TCP/UDP Message Service
TCP/UDP message service provides a simple form of TCP/UDP socket communications intended for
access to CIP objects of the Controller from a system where EtherNet/IP is not supported. With this
function, you can change settings and perform I/O control for the Controller and Units connected to the
NX Bus. TCP/UDP message service can be performed simultaneously with tag data link communica-
tions.
This function is available only with NX102 CPU Units.
