Launch of CC-Link IE Field Basic

Jan 10, 2017

The CC-Link Partner Association (CLPA), working to expand the adoption of the industrial open network CC-Link IE, has announced the launch of CC-Link IE Field Basic, an open-field network using general-purpose 100Mbps Ethernet communication that is a new network clpa graphicmode in the CC-Link IE Ethernet-based integrated network lineup. Specifications enabling communication compatibility with software alone lower the threshold for control device networks. And CC-Link IE Field Basic enables greater transparency and high-efficiency production facilities.

CC-Link IE Field Basic development history

A key feature of CC-Link IE is the wide 1Gbps bandwidth unseen in other industrial networks. This bandwidth allows the simultaneous handling of process operation data (I/O updates, etc.) along with nearly unlimited levels of asynchronous communication, such as production and operational performance data. These are known as “cyclic” and “transient” traffic with CC-Link IE and enable systems to maintain performance even under demanding application conditions.

CC-Link IE consists of CC-Link IE Control network as a trunk network for inter-controller communication and CC-Link IE Field network for connecting controllers to field devices. These features have led to the adoption of CC-Link IE not only in Asia but all over the world; however, as attention increasingly focuses on the Industrial Internet of Things, low-end devices and small-scale equipment (conventionally on the fringe of networks) are now in need of connectivity as never before. Rather than high speed, these production sites demand excellent cost-performance and easily implemented networks.

The CC-Link Partner Association has released the CC-Link IE Field Basic specification as a solution that offers easier network compatibility while maintaining mutual connectivity with CC-Link IE.

CC-Link IE Field Basic features

1) Implementation with general purpose Ethernet devices 

CC-Link IE Field Basic achieves the cyclic communication required for device control with software at the network protocol application layer. General purpose Ethernet compatible devices can support CC-Link IE Field Basic through software implementation alone. Transient communication leverages the benefits of Ethernet TCP/IP to make the CLPA’s Seamless Message Protocol (SLMP) available. Moreover, other Ethernet applications such as HTTP and FTP can be simultaneously implemented and used together.

2) Inherits CC-Link IE features such as network transparency

Functions provided by CC-Link IE enable production-site visualization, such as linking production-site devices and host-IT systems, are inherited by CC-Link IE Field Basic. Devices which could not previously be connected to CC-Link IE can now be integrated and managed.

3) CC-Link IE Field Basic compatible slave devices can be developed quickly at low cost

Vendor development is quick, as only software implementation is required for CC-Link IE Field Basic compatible devices. Devices compatible with other protocols can share hardware, promoting lower costs. Furthermore, not only PLCs but also general-purpose computers can be used as master devices.

CC-Link IE Field Basic has received support from Balluff, CKD, Hilscher, IDEC, Mitsubishi Electric, Molex, Phoenix Contact, Renesas Electronics and others. The CC-Link Partner Association encourages such support and promotes vendor development; therefore the CLPA is launching a conformance-testing campaign during which vendors who declare their intention to develop a CC-Link IE Field Basic compatible product by July 31, 2017 may receive an official CLPA conformance test certificate free of charge.
