CC-Link
The CC-Link is a serial-based open field network.
This network is operated by the non-profit organization CC-Link Partner Association (CLPA) and has
the following features:
1. Achievement of the high-speed and stable I/O response
2. Efficiency promoted by wiring saving
3. Flexible responses to multivendors
4. High reliability realized by RAS (Reliability, Availability, and Serviceability) functions
For detailed information on CC-Link, refer to the documents issued by the CC-Link Partner Associa-
tion and instruction manual for the master device used.
5-2
EtherCAT
EtherCAT is an open field network compatible with Ethernet.
EtherCAT is an open network designed with the operating principle to realize the high-speed
communication and the architecture suitable for motion control, such as a function that
synchronizes between highly accurate nodes, featuring the simpler wiring compared to Ethernet
without requiring a switching hub.
The structure is supported for the needs of decentralizing I/O devices including the safety.
The single network design will also save the wiring within the devices. Not only speeding up,
increasing the accuracy of the device control, or improving the device production cycle time,
EtherCAT also helps you to lower the cost associated with device installation or maintenance,
such as standardizing cable wiring or simplifying the assembly.
For detailed information on EtherCAT, refer to the documents issued by EtherCAT Technology Group
and the instruction manual for the master device used.
5-3
EtherNet/IP
EtherNet/IP is a standard industrial Ethernet network which adopts the widely used Ethernet TCP/
IP protocol and has CIP (Common Industrial Protocol) installed as the control protocol at the
application layer.
It is regulated by IEC Standard IEC 61158.
Making the most of its ability for rapid and wide-range communication of large volumes of control
and monitoring data from the field, it promises improved operation rates and quality and reduced
TCO.
For detailed information on EtherNet/IP, refer to the documents issued by the ODVA (Open De-
viceNet Vendor Association) and instruction manual for the master device used.
