
CIP Message Communications
You can send CIP commands to devices on the EtherNet/IP network when required by executing
CIP communications instructions in a program.
As a result, it is possible to send and receive data with the devices on the EtherNet/IP network.

BOOTP Client
If the built-in EtherNet/IP port on an NJ/NX-series CPU Unit is set in the BOOTP settings, the
BOOTP client 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 you can read and write files on workstations and com-
puters 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.
*1. A separate NTP server is necessary to automatically adjust the Controller clocks.

Socket Services
Socket services can be used to send and receive data between general-purpose applications and
Controllers.
Through the communications services with sockets, you can send and receive data to and from re-
mote nodes, i.e., between the host computer and Controllers or between Controllers.
You can execute socket communications instructions in order in a program to execute communica-
tions processes with the socket services.
There are two socket services, the UDP socket service and TCP socket service.

DNS Client for Specifying Host Names
When you specify an NTP server, SNMP manager, or the destination of socket instructions or CIP
communications instructions, you can use the host name, as well as its IP address (DNS client or
hosts settings).
This will help identify the IP address automatically even after the IP addresses of relevant servers
are changed due to system revisions.
*1. A separate DNS server is necessary when you use host names with the DNS client.
*2. The DNS server is specified directly using its IP address.
