*1 If tag data links are being used, use 100Base-TX.
*2 Here, pps means "packets per second" and indicates the number of packets that can be processed in one sec-
ond.
*3 To use a data size of 505 bytes or higher, the system must support a large forward open (an optional CIP spec-
ification). The CS/CJ-series Units support a large forward open, but before connecting to nodes of other com-
panies, confirm that those devices also support it.
*4 If the parameters of the EtherNet/IP Unit are changed, the Unit is restarted. When other nodes are in commu-
nications with the affected node, the communications will temporarily time out and automatically recover later.
*5 Because the EtherNet/IP Unit is equipped with an IGMP client (version 2), unnecessary multicast packets can
be filtered by an Ethernet switch that supports IGMP snooping.
*6 The EtherNet/IP Unit uses the TCP/UDP port numbers shown in the following table.
Do not set the same port number for more than one TCP/UDP service.
Service
EIP data links

CIP messages
FTP client data transfer port

*7 A CPU Unit with unit version 1.01 or later and Sysmac Studio version 1.02 or higher are required to use CPU
routing.
