In the industrial automation industry, the protocol compatibility of production equipment has always been a key pain point in smart manufacturing upgrades.
CC-Link IE is widely used in Japanese discrete manufacturing equipment with its gigabit transmission rate and high reliability; EtherCAT has become the de facto standard in the high-end motion control field with its microsecond-level real-time advantage.
When these two mainstream protocol systems meet, how to break data barriers and achieve cross-platform collaboration has become a core issue for many companies to promote intelligent transformation.
The core implementation path can be divided into a dual choice of software and hardware.
There are essential differences between CC-Link IE and EtherCAT in communication mechanisms and data frame structures, and there are natural technical barriers to direct communication.
The current mainstream conversion solutions can be divided into two categories: hardware gateway conversion and software protocol stack development. Among them, industrial sites prefer hardware solutions with stronger stability.
Hardware conversion is an industrial-grade plug-and-play solution.
The professional protocol conversion gateway achieves seamless connection between the two protocols through hardware-level protocol parsing and data mapping without modifying the original equipment program. It is the preferred solution for current industrial sites.
In this field, Nidaxun Automation relies on its technical accumulation in the field of industrial communications to launch the CC-Link IE to EtherCAT gateway, which provides reliable support for cross-protocol collaboration.
Take the production line upgrade project of an auto parts manufacturing company as an example. The original stamping production line adopted the Mitsubishi CC-Link IE control system, and a batch of German EtherCAT servo presses were introduced to improve processing accuracy.
The project team introduced Nidaxon Automation CC-Link IE to EtherCAT gateway and completed the cross-protocol system integration in just 3 days.
The specific performance is: dual role configuration, the gateway is in CC-Link
The IE side is recognized by Mitsubishi PLC as an intelligent slave station, and the EtherCAT side serves as a complete master station to manage the servo press; visual mapping, through the gateway supporting software, bidirectional mapping of the PLC control register and the process data object (PDO) of the EtherCAT slave station, supports drag-and-drop operation; high-precision synchronization, with the help of PTP clock synchronization technology, achieves microsecond-level time alignment across protocol systems, ensuring that stamping accuracy is controlled within ±0.05mm.
After the implementation of the project, the overall efficiency of the production line equipment increased by 28%, the debugging cycle was only 1/5 of the traditional transformation plan, and the transformation cost was reduced by more than 60%.
Software conversion is the technical path for customized scenes.
For scenarios with special customization requirements, soft conversion can be achieved by deploying dual protocol stack development middleware, but real-time and reliability issues need to be solved. It usually needs to be used with a hard real-time operating system, which is suitable for R&D-oriented enterprises or specific customized projects.
In terms of key technical points, it is crucial to ensure the stable operation of cross-protocol communication.
First, clock synchronization is the core.
The minimum cycle communication cycle of CC-Link IE is 1ms, while the synchronization accuracy of EtherCAT can reach microsecond level. During conversion, a gateway supporting the IEEE 1588 PTP protocol is required to achieve clock alignment on both sides of the network to avoid control errors caused by data transmission time differences.
Nidaxun gateway has a built-in high-precision clock chip, and the synchronization error can be controlled within 1μs.
Secondly, data mapping needs to be accurate.
The essence of protocol conversion is the translation of data formats. It is necessary to establish an accurate mapping between the remote register (RX/RY) of CC-Link IE and the process data object (PDO) of EtherCAT according to actual business needs.
The configuration software provided by Nidaxun supports visual mapping configuration and can automatically verify data length matching to avoid configuration errors.
Finally, adaptability to industrial environments cannot be ignored.
There are complex working conditions such as electromagnetic interference and temperature fluctuations in industrial sites. The gateway needs to have features such as wide temperature operating range (-40℃~85℃) and high anti-interference level (IEC 61000-4 standard).
Nidaxun gateway uses industrial-grade components and has an IP30 protection design, so it can be installed directly in the control cabinet.
In summary, the protocol conversion between Nidaxun Automation CC-Link IE and EtherCAT is not only a technical integration, but also a key step in the upgrading of enterprise intelligent manufacturing.
By introducing gateway equipment from professional brands such as Nidaxun Automation, companies can introduce high-performance equipment at low cost without replacing the original mature control system, protecting existing investments while improving production efficiency.
In the context of Industry 4.0, the demand for equipment interconnection will continue to grow, and protocol conversion technology will become a key infrastructure to break data silos and unleash the potential of equipment.
In the future, with the integration of edge computing and artificial intelligence technology, protocol conversion gateways will not only meet data transmission needs, but will also have intelligent functions such as edge analysis and fault warning, bringing greater value to industrial production.
