*1. In this case, pps means "packets per second" and indicates the number of packets that can be processed in one 

       second. 

*2. When using the EtherNet/IP Unit with version 3.0 or later. When using the EtherNet/IP Unit with version 

       2.1 or earlier, the maximum allowed communications bandwidth per Unit is 6,000 pps. When using the EtherNet/IP 

       Unit with version 3.0 or later, the Network Configurator with version 3.57 or higher is required. 

*3. Network symbols can be used only by the NJ501-[][][][], NJ301-[][][][], CJ2H-CPU6[]-EIP and CJ2M-CPU3[]. 

*4. To use 505 to 1,444 bytes as the data size, the system must support the Large Forward Open standard (an optional 

       CIP specification). The CS/CJ-series Units support this standard, but before connecting to nodes of other companies, 

       confirm that those devices also support it. 

*5. If the maximum data size is exceeded, the data refreshing with the CPU Unit will extend over two or more cycles. 

*6. If status layout is selected in the user settings, the maximum number of tags that can be received is 19 tags. 

*7. If parameters are changed in the EtherNet/IP Unit, however, the EtherNet/IP Unit will be restarted. When other nodes 

       are communicating with the affected node, the communications will temporarily time out and automatically recover 

       later. 

*8. Because the EtherNet/IP Unit is equipped with an IGMP client, unnecessary multicast packets can be filtered by using 

       a switching hub that supports IGMP snooping. 

*9. The EtherNet/IP Unit uses the TCP/UDP port numbers shown in the following table.

Service	Protocol		Port number		Remarks
	CJ1/CJ2	NJ	CJ1/CJ2	NJ	CJ1/CJ2	NJ
Used by system	---	UDP	---	2223, 2224	Fixed value
Tag data links	UDP		2222
Class3, UCMM	TCP/UDP		44818
DNS	UDP		53
BOOTP client	---	UDP	---	68
FINS/UDP service	UDP	---	9600	---	Port numbers in the Unit Setup can be changed with the CX-Programmer.	Port numbers in the Unit Setup can be changed with the Sysmac Studio.
FINS/TCP service	TCP	---	9600	---
FTP	TCP		20, 21	21
SNTP	UDP		123
SNMP	UDP		161
SNMP trap	UDP		162

*10.When NJ-Series CPU Units is described, Supported only by the EtherNet/IP Units with unit version 2.1 or later and 
       NJ-Series CPU Units with unit version 1.01 or later.

Network Configurator Requirements

The Network Configurator Ver. 3.0 or higher is a software package designed for building, setting, and controlling a multi-vendor EtherNet/IP Network using OMRON's EtherNet/IP. It is included in CX-One version 3.0. The Network Configurator provides the following functions for building, setting, and controlling EtherNet/IP.

Location on Network		A single node address is used (only when directly connected to EtherNet/IP).
Number of Units that can be  connected to Network		A single Network Configurator per Network  (More than one Configurator cannot be used in the same system.)
Main  functions	Network control  functions	The Network configuration can be created and edited regardless of whether the  Network Configurator is online or offline.  The Network configuration can be read from a file or the network.
	Configuration  functions	The EDS files used by the Network Configurator can be installed and deleted.
Supported file formats		Configurator network configuration files (*.ncf)  Configuration files (*.ncf) created using the Network Configurator for EtherNet/IP  (version 2) can be imported by selecting External Data - Import from the File Menu.
