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 built-in EtherNet/IP port on the NJ-series CPU Unit
and another CPU Unit or EtherNet/IP Unit, use tag data link settings that match the Unit with the lower
communications performance.
z Differences in Tag Data Link Performance Specifications
*1 Here, pps means “packets per second” and indicates the number of packets that can be processed in one sec-
ond.
*2 To use a data size of 505 to 1,444 bytes, the system must support a large forward open (an optional CIP spec-
ification). The SYSMAC CS/CJ-series Units support a large forward open, but before you connect to nodes of
other companies, confirm that those devices also support it.
*3 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.
