*5. It is not possible to use the maximum number of words simultaneously for all banks, because the memory capacity for
variables with a Retain attribute is limited to 1.5 MB.
*6. For terminology, refer to the NJ/NX-series CPU Unit Motion Control User's Manual (Cat. No. W507).
*7. Data will be refreshed at the set interval, regardless of the number of nodes.
*8. "pps" means packets per second, i.e., the number of communications packets that can be sent or received in one second.
*9. The allowable bandwidth varies depending on the RPI of the connection in use, the primary task period, and the number of
ports simultaneously used for EtherNet/IP communications.
*10. When tag sets that exceed the total of 40 are set, a Number of Tag Sets for Tag Data Links Exceeded (840E0000 hex)
occurs.
*11. As the EtherNet/IP port implements the IGMP client, unnecessary multi-cast packets can be filtered by using an Ethernet
switch that supports IGMP Snooping.
*12. An NX102-££00 CPU Unit with unit version 1.46 or later, NX102-££20 CPU Unit with unit version 1.37 or later, and Sys-
mac Studio version 1.46 or higher are required to use the secure socket services.
*13. Refer to the NJ/NX-series CPU Unit OPC UA User's Manual (Cat. No. W588) for information on the specifications for the
OPC UA server.
*14. A ring topology can be used with project unit version 1.40 or later.
*15. However, for project unit version earlier than 1.40, the data must be within four frames.
*16. You can check the I/O allocation status with the Sysmac Studio. Refer to the NJ/NX-series CPU Unit Software User's
Manual (Cat. No. W501) for how to check the I/O allocation status. Also, refer to the relevant manuals for specific Units for
the maximum I/O data size per NX Unit.
*17. These are values in continuous operation state.
