*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

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

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.
