The CC-Link Partner Association, based in Nagoya Japan, has completed the specification for CC-Link IE TSN. This network was developed to meet future market demands and includes Time Sensitive Networking (TSN) technology. It can facilitate the integration of Operational Technology (OT) and IT.
With IP and control communication technology, it facilitates flexible implementation with various types of equipment and achieves mixed usage of information communications. CC-Link IE TSN should improve efficiency and reduce time for the construction of smart factories using the IIoT. More details of the CC-Link IE TSN specification will be published on the CLPA Members Site.
The CC-Link IE specification was released in 2007 as a 1Gbps Ethernet-based open industrial network and has expanded to motion and safety control after starting from general input/output control. It features high-speed and large-capacity control communication (cyclic data) that combines with non-control communication (transient data). The two can coexist with the 1Gbps bandwidth. Network errors are easy to diagnose. This network should bring a range of benefits to different industries since it is simple to build a system that controls and monitors a production site as well as collects and analyzes information.
As IIoT systems have progressed to the practical stage in recent years, market demands for a range of devices implementing general purpose Ethernet communication have increased. Requests for high function motion control equipment and protocol implementation for various types of equipment have also increased. CC-Link IE TSN is a network that improves the performance and functions of the current CC-Link IE. Plus, it has increased openness through the use of TSN technology.
Features of CC-Link IE TSN
1. Flexible IIoT system construction
–Adopts TSN Ethernet communication technology as a time sharing method
–Enables collection of information from end devices by IP communication while securing real-time control communication
2. Faster time to market and reduced downtime
–Easier network diagnosis by using general purpose Ethernet diagnostic tools compliant with SNMP
–By means of time synchronization of compatible devices, it is easy to investigate the cause of problems
3. Further productivity improvement
–With the improvement of communication performance, CC-Link IE TSN can offer a best in class motion control operation cycle time of better than 31.25µs
–Segregation of high and low performance device communication, leading to optimized performance for all network stations and the system as a whole
4. Diversification of development methods
–Offers hardware (ASIC and other device based) and software (protocol stack) development methods
–Supports both 1Gbps and 100Mbps
The detailed specification of CC-Link IE TSN will be released to CLPA partner companies through the CC-Link website. Those partners who were involved in formulating specifications are considering product development and compatible products are expected to be released from 2019.
