*1. Execution objects and variable tables (including variable names)
*2. Does not include Holding, DM, and EM Area memory for CJ-series Units.
*3. Does not include CIO and Work Area memory for CJ-series Units.
*4. Refer to the NJ/NX-series CPU Unit Motion Control User's Manual (Cat. No. W507) for descriptions of axes.
*5. Data will be refreshed at the set interval, regardless of the number of nodes.
*6. "pps" means packets per second, i.e., the number of communications packets that can be sent or received in one second.
*7. 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.
*8. An NX701- CPU Unit with unit version 1.24 or later supports OPC UA.
*9. If set to 0, it is assumed that is set to 50.
*10.The number of value attributes is defined by the following formula.
Number of value attributes = (Number of basic data type variables) + (Number of array-specified elements) + (Number of
values in the structure)
*11.However, the data must be within eight frames.
