Tag Data Links with Other Models
The performance of tag data links depends on the CPU Unit model and EtherNet/IP Unit model as
shown below.
When you use tag data links between the built-in EtherNet/IP port on an NJ/NX-series CPU Unit and
another CPU Unit or EtherNet/IP Unit, configure the tag data link settings based on either Unit, which-
ever has the lower level of communications performance.
