A port for communications with various kinds of Support
Software running on a personal computer.
TCP/IP and UDP/IP
Programless cyclic data exchange is performed with the
devices on the EtherNet/IP network.
CIP commands are sent to or received from the devices on
the EtherNet/IP network.
Data is sent to and received from any node on Ethernet
using the UDP or TCP protocol. Socket communications
instructions are used.
Files are transferred via FTP from the CPU Unit to comput-
ers or Controllers at other Ethernet nodes. FTP client com-
munications instructions are used.
Files can be read from or written to the SD Memory Card in
the CPU Unit from computers at other Ethernet nodes.
Clock information is read from the NTP server at the speci-
fied time or at a specified interval after the power supply to
the CPU Unit is turned ON. The internal clock time in the
CPU Unit is updated with the read time.
Built-in EtherNet/IP port internal status information is pro-
vided to network management software that uses an SNMP
manager.
Control information is exchanged in cyclic communications
between the EtherCAT master and slaves.
Control information is exchanged in noncyclic event commu-
nications between the EtherCAT master and slaves. The fol-
lowing application protocol is supported. CoE (CANopen
over EtherCAT)
Information is read from connected slave devices and the
slave configuration is automatically generated.
Time is synchronized by sharing the EtherCAT system time
among all EtherCAT devices (including the master).
The frames that are sent by the master and the frames that
are received by the master can be saved. The data that is
saved can be viewed with WireShark or other applications.
The slaves can be enabled or disabled as communications
targets.
Temporarily disconnects a slave from the EtherCAT network
for maintenance, such as for replacement of the slave, and
then connects the slave again.
SDO messages that conform to the CANopen standard can
be sent to slaves via EtherCAT
FTP client instructions (*), CIP communications instructions,
socket communications instructions, SDO message instruc-
tions, no-protocol communications instructions, and protocol
macro instructions
The output on the NJ-P3001 Power Supply Unit turns ON
in RUN mode.
Events are recorded in the logs listed on the right.
• System event log,
• Access event log,
• User-defined event log
