Built-in Ethernet ports
Data can be displayed and set for other
hosts on the Ethernet network. For exam-
ple, it is possible to display and set at one
NSJ Controller the data of another NSJ
Controller or PLC.
Ethernet can be used for CX-One (CX-Pro-
grammer, CX-Designer, etc.). Screen data
and ladder programs can be transferred
from the host computer.
Accessing Display Section Memory Cards:
Ethernet can be used for accessing special
tools from the host computer or accessing
Display Section Memory Cards by FTP. For
example, Display Section recipe data,
alarms, and data log files can be acquired
from the host computer.
Accessing the host from host applications:
The Controller Section of an NSJ Controller
can be accessed from the host computer
using FINS communications. For example,
NSJ Controller DM can be read and written
from applications on the host computer.

Screen data can be transferred between NSJ Controllers using the CX-
Designer across networks only if the NSJ Controllers are connected by the
built-in Ethernet ports on the NSJ controller.
The internal operation of the NSJ Controller is described in this section.
• The Controller Section and Display Section exchange data using the
Inner bus.
• The DeviceNet master function as well as the NSJ Controller Link Unit or
NSJ Ethernet Unit (Expansion Units) are handled as CJ-series CPU Bus
Units. CIO Area and DM Area words are allocated to these according the
unit numbers.

The same functions are supported as
described to the left for the built-in Ethernet
port.
The same functions are supported as
described to the left for the built-in Ethernet
port (except that Display Section Memory
Cards cannot be accessed).
In addition, the following functions are sup-
ported:
Accessing Controller Section Memory
Cards
Clock-setting using SNTP function
TCP/IP compatibility
