*1 If tag data links are being used, use 100Base-TX or 1000Base-T.
*2 Here, pps means "packets per second" and indicates the number of packets that can be processed in one sec-
ond.
*3 If the two built-in EtherNet/IP ports are used simultaneously, the maximum communications data size for two
ports in total will be reached.
*4 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, NJ, and NX-series Units support a large forward open, but before connecting to nodes
of other companies, confirm that those devices also support it.
*5 If the parameters of the built-in EtherNet/IP port are changed, the port is restarted. When other nodes are in
communications with the affected node, the communications will temporarily time out and automatically
recover after the restart.
*6 Because the built-in EtherNet/IP port is equipped with an IGMP client (version 2), unnecessary multicast pack-
ets can be filtered by an Ethernet switch that supports IGMP snooping.
*7 The built-in EtherNet/IP port 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.
