Communications Services Overview
The following communications services are supported.
CIP (Common Industrial Protocol) Communications Services
1) Tag Data Links (Cyclic Communications)
A program is not required to perform cyclic data exchanges with other devices
in the EtherNet/IP network.
Normally, the tag data links in an EtherNet/IP Unit or built-in EtherNet/IP port
are started by grouping the tags created with the Network Configurator into a
tag set, and establishing a connection with the target device using that group
of tags. One connection is used per group (tag set). Up to 32 connections for
the CJ2M and up to 256 connections for other CPU Units) can be registered.
The following table gives the tag and tag set specifications.
