Outline of TCP/UDP Message Service
TCP/UDP socket communication to enable simple access to the CIP object of the Controller from sys-
tems which do not support EtherNet/IP is possible. This enables change of settings and I/O control of
the units connected to the Controller and NX bus. The service can be executed simultaneously with the
tag data link communications.
This service can only be used on the NX102 CPU Unit.
