EtherCAT slaves Maximum Number of Slaves 16
CJ-Series Units Maximum Number of Units Not supported
Communications
Peripheral USB Port Not supported
Built-in EtherNet/IP
Port
Communications Protocol TCP/IP and UDP/IP
CIP
Communications
Service
Tag Dta Links
Programless cyclic data exchange is performed with the devices on the
EtherNet/IP network.
Message
Communications
CIP commands are sent to or received from the devices on the EtherNet/IP
network.
TCP/IP
Applications
Socket Services
Data is sent to and received from any node on Ethernet using the UDP or TCP
protocol. Socket communications instructions are used.
FTP Client
Files are transferred via FTP from the CPU Unit to computers or Controllers
at other Ethernet nodes. FTP client communications instructions are used.
FTP Server
Files can be read from or written to the SD Memory Card in the CPU Unit from
computers at other Ethernet nodes.
Automatic Clock
Adjustment
Clock information is read from the NTP server at the specified 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.
SNMP Agent
Built-in EtherNet/IP port internal status information is provided to network
management software that uses an SNMP manager.
EtherCAT Port
Supported
Services
Process Data
Communications
A communications method to exchange control information in cyclic
communications between the EtherCAT master and slaves.
This communications method is defined by CoE.
SDO
Communications
A communications method to exchange control information in noncyclic event
communications between EtherCAT master and slaves.
This communications method is defined by CoE.
Network Scanning
Information is read from connected slave devices and the slave configuration
is automatically generated.
DC (Distributed Clock)
Time is synchronized by sharing the EtherCAT system time among all
EtherCAT devices (including the master).
Packet Monitoring
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.
Enable/Disable Settings for Slaves The slaves can be enabled or disabled as communications targets.
Disconnecting/Connecting Slaves
Temporarily disconnects a slave from the EtherCAT network for maintenance,
such as for replacement of the slave, and then connects the slave again.
Supported
Application
Protocol
CoE SDO messages of the CAN application can be sent to slaves via EtherCAT
Serial
Communication
Protocol
Host link (FINS), no-protocol, and Modbus-RTU master (when connected to
the Serial Communications Option Board)
Communications Instructions
FTP client instructions, CIP communications instructions, socket
communications instructions, SDO message instructions, noprotocol
communications instructions, and Modbus RTU protocol instructions

MC Test Run Motor operation and wiring can be checked from the Sysmac Studio.
Synchronizing
The project file in the Sysmac Studio and the data in the CPU Unit can be
made the same when online.
Differentiation Monitoring You can monitor when a variable changes to TRUE or changes to FALSE.
