on the CX-Integrator.
The following communications services are supported.
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-EIP21 and up to 256 connections for other CPU Units) can be reg-
istered.
The following table gives the tag and tag set specifications.
