EtherNet/IP Unit and Built-in EtherNet/IP Port Specifications
Section 2-1
Note
(1) In this case, pps means “packets per second” and indicates the number
of packets that can be processed in one second.
(2) 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 SYS-
MAC CS/CJ-series Units support this standard, but before connecting to
nodes of other companies, confirm that those devices also support it.
MAC CS/CJ-series Units support this standard, but before connecting to
nodes of other companies, confirm that those devices also support it.
(3) If the maximum data size is exceeded, the data refreshing with the CPU
Unit will extend over two or more cycles.
(4) If status layout is selected in the user settings, the maximum number of
tags that can be received is 19 tags.
(5) If parameters are changed in the EtherNet/IP Unit, however, the Ether-
Net/IP Unit will be restarted. When other nodes are communicating with
the affected node, the communications will temporarily time out and au-
tomatically recover later.

tomatically recover later.
(6) Because the EtherNet/IP Unit is equipped with an IGMP client (version
2), unnecessary multicast packets can be filtered by using a switching
hub that supports IGMP snooping.

(7) The EtherNet/IP Unit uses the TCP/UDP port numbers shown in the fol-
lowing table.
(8) Network symbols can be used only with a CJ2H-CPU6
