CJ-series EtherNet/IP Units Operation Manual for NJ-series CPU Unit (W495)
7-4 Tag Data Links with Models Other
than NJ-Series CPU Units
The performance of tag data links depends on the CPU Unit and EtherNet/IP Unit model as shown
below. When you use tag data links between the EtherNet/IP Unit and another EtherNet/IP Unit or CPU
Unit, use tag data link settings that match the Unit with the lower communications performance.

Differences in Tag Data Link Performance Specifications
*1 The maximum number of tags is given for the following conditions.
• All tag sets contain eight tags.
• The maximum number of tag sets (32) is registered.
