Omron NX502-1 Series Manual

Machine Automation Controller NX1
21
*1. Execution objects and variable tables (including variable names)
*2. Memory used for CJ-series Units is included.
*3. The value can be set in 1-word increments. The value is included in the total size of variables without a Retain attribute.
*4. The value can be set in 1-word increments. The value is included in the total size of variables with a Retain attribute.
*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.Ring topology is supported with the project version 1.40 or later of NX102-@@00.
Slaves on a ring topology should support a ring topology. If Omron slaves, please see the user's manual of slaves.
*13.For project unit version earlier than 1.40, the data must be within four frames.
*14.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.
