15-1 System Configuration and Features
N14/20 CPU Units have one built-in Ethernet port. N 3 0/40/60 CPU Units have two Ethernet ports, and
the second port is only for switch. A variety of protocols make available a wide range of applications for
use on an Ethernet network. The protocols can be selected include sending and receiving data by
TCP/IP or UDP/IP (socket services), sending and receiving commands by OMRON
’ s standard protocol
FINS, and automatically adjusting the PLC ’ s internal clock by SNTP.
The following diagram shows an example of an overall system configuration using CP2E N -type
CPU Units.
