Tag Data Links With Models Other Than Nj-Series Cpu Units - Omron CJ1W-EIP21 Operation Manuals

7 Tag Data Link Functions
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.
