Features of Built-in EtherNet/IP Port on NJ/NX-series CPU Units

 Tag Data Links
Cyclic communications between Controllers or between Controllers and other devices are possible
on an EtherNet/IP network. Tag data links can quickly perform data exchanges.
 CIP Message Communications
You can send CIP commands to devices on the EtherNet/IP network when required by execution of
CIP communications instructions in a program. As a result, it is possible to send and receive data
with devices on the EtherNet/IP network.
 BOOTP Client
If the NJ/NX-series CPU Unit built-in EtherNet/IP port is set in the BOOTP settings, the BOOTP cli-
ent operates when the Controller power is turned ON, and the IP address is obtained from the
BOOTP server. It is possible to set all of the IP addresses of multiple built-in EtherNet/IP ports at the
same time.
 FTP Server for File Transfers to and from Host Computers
An FTP server is built into the Controller. You can use it to read and write data within the Controller
as files from workstations and computers with FTP clients. The FTP server enables the transfer of
large amounts of data from a client without any additional ladder programming.
 FTP Client for File Transfers to and from Host Computers
An FTP client is built into the Controller so that you can read and write files on workstations and
computers that have an FTP server from the Controller.
You can use the FTP client communications instructions to transfer one or more files between the
Controller and an FTP server.
 NTP Client for Automatic Controller Clock Adjustment
The clocks built into Controllers connected to Ethernet can be automatically adjusted to the time of
the clock in the NTP server. If all of the clocks in the system are automatically adjusted to the same
time, time stamps can be used to analyze production histories.
* A separate NTP server is necessary to automatically adjust the Controller clocks.
 Socket Services
Socket services can be used to send/receive data between general-purpose applications and Con-
trollers. You can use these communications services to send and receive any data to and from
remote nodes, i.e., between host computers and Controllers or between Controllers. You can exe-
cute socket communications instructions in order in a program to execute communications pro-
cesses with the socket services. There are two socket services, the UDP socket service and TCP
socket service.
 DNS Client for Specifying Host Names
You can directly specify IP addresses, but you can also use the host names instead of the IP
addresses for NTP servers, SNMP managers, or the destinations of socket instructions and CIP
communications instructions (DNS client or hosts settings). This is useful, for example, when server
IP addresses change for system revisions because the IP addresses are automatically found when
host names are used.
* A separate DNS server is necessary to use host names with the DNS client.
* The DNS server is specified directly using its IP address.
