Beckhoff is advancing industrial automation with its new ED Series EtherCAT terminals, delivering improved installation, diagnostics and maintenance capabilities while ensuring compatibility with existing EtherCAT infrastructure and investments.
The company said that since the launch of the first system terminal in 2003, EtherCAT has helped shape the future of high-performance machine communication and control, and the launch of the ED series is proof of its constant evolution.
Today, EtherCAT is used in 78 countries, supported by more than 8000 member companies and has surpassed 100 million deployed nodes globally, cementing its position as the defining standard in modern industrial automation.
According to Supriya Suhale, category manager for Beckhoff Automation Australia, the goal behind the ED series was not to reinvent a whole new IO system, but rather to refine and future-proof it.
“Beckhoff is taking the next step with the launch of its new ED Series – an evolution of its widely adopted EtherCAT terminal platform that modernises usability, serviceability and installation, while protecting the investments customers have already made in existing infrastructure,” she said.
“The intention was to modernise the portfolio with a new look, improved mechanics and a technological update, while remaining price competitive.”
Suhale underscores the importance of the ED Series as an IO refresh, or even evolution, rather than an entirely new platform – a deliberate decision aimed at maintaining continuity for existing users.
“Creating an entirely new system would have disrupted thousands of installations globally and forced customers into costly infrastructure overhauls,” explained Suhale.
“Instead, the ED Series maintains the same form factor and architecture compatibility as the existing EL Series, allowing users to integrate new modules alongside established terminals on the same EtherCAT network.”
This approach protects customer investments and allows modernisation in increments, providing customers with the opportunity to mix and match ED and EL terminals, while maintaining functional compatibility.
Adding to its versatility and integration into the Beckhoff stable, Suhale added that the ED Series is fully compatible with TwinCAT 3 and integrates easily into existing EtherCAT environments, although the updated functionality will require new ESI files, may require software updates during integration, and are not a drop-in replacement to the existing terminals of similar signal and channel type.
Designed to perform
Suhale highlighted several tangible enhancements across the full lifecycle, from installation through to servicing, keeping ease of use front and centre.
“We have now included a tool-free push-in wiring connection to speed up the installation process,” she said.
The ED Series also introduces app-based diagnostics, allowing technicians to access terminal diagnostic data directly from a mobile device or tablet. Importantly, the system operates in read-only mode to avoid introducing operational or cybersecurity risks.
Additional practical improvements include:
- Consistent form factors and LED layouts for easier troubleshooting and maintenance.
- DMC code traceability on each terminal for simplified spare parts management and quality assurance.
- Full backward compatibility with existing cabinet layouts and DIN rail infrastructure.
- Simplified replacement and lifecycle management in large installations.
“Overall, the focus was to make installation, commissioning and maintenance faster and simpler,” Suhale added.
Less downtime, faster commissioning
Beyond convenience, Beckhoff positions the ED Series as a solution aimed directly at lowering total cost of ownership.
“Faster commissioning, simplified maintenance, easier replacements and app-based fault finding all contribute to reduced downtime and improved system availability,” said Suhale.
For OEMs building machines at scale, the optional pluggable wiring system offers another major advantage by dramatically reducing cabinet wiring time during repetitive machine builds.
Meanwhile, maintenance teams benefit from simplified diagnostics that do not require in-depth EtherCAT expertise.
“The read-only app allows technicians to scan a terminal, read live status data and identify faults immediately on the plant floor,” Suhale explained.
Looking to the industries set to benefit most, Suhale highlighted the automotive, packaging, food and beverage, general manufacturing and process industries.
“We are proud to produce a solution that enhances production in high-volume manufacturing environments, and all industries that make use of controls and IO systems, for that matter. Even small reductions in commissioning time or maintenance complexity can translate into substantial operational savings,” she added.
Supporting the long-term automation vision
The ED Series reflects Beckhoff’s broader strategy around modular, scalable and future-proof automation.
“The ED platform integrates directly into Beckhoff’s wider ecosystem, which spans TwinCAT software, AI integration, machine vision, drive technology and PC-Based control,” she explained.
“The IO layer is often the most extensive part of any automation architecture, and the ED Series ensures this layer remains modern, flexible and fully aligned with the future direction of industrial automation.”
EtherCAT’s global growth continues
As the inventor of EtherCAT, Beckhoff continues to play a central role in the development of one of the world’s most widely adopted industrial Ethernet technologies.
“With the ED Series, Beckhoff is not asking customers to start over. We always evolve our hardware to reduce integration complexities and without forcing platform changes,” she said.
“We pride ourselves in developing a range that is a carefully considered evolution – one that modernises the user experience while preserving the reliability, scalability and openness that helped EtherCAT become an industry standard in the first place.”
