EtherCAT®

Real-time industrial Ethernet Technology

EtherCAT® is a very flexible real-time Industrial Ethernet protocol published as IEC 61158 standard. The data exchange follows the 'processing on the fly' principle which means that data is passed by each slave device with just a minimal delay before it is processed. This makes EtherCAT to the ideal solution for Ethernet based industrial control systems with many distributed I/Os and/or cycle times less than 100 µs.

Development Services

esd electronics (esd) has been developing EtherCAT-Hardware and Software solutions since 2008. We offer standard products like EtherCAT Master and EtherCAT Workbench as well as customer specific solutions. As an active member of the EtherCAT Technology Group (ETG) (www.ethercat.org) we offer engineering services for all aspects of this technology.

Training and Workshops

Since 2008 esd has been conducting workshops on EtherCAT technology and supporting customers in the development of optimized EtherCAT hardware or software products. Training courses can be held at esd headquarters in Hanover or at the customer's site. The type, depth and duration of the measure is determined by the customer together with esd, taking into account the requirements of his project.

EtherCAT Technology

  • Based on 100 MBit/s standard Ethernet (100BASE-TX or 100BASE-FX) without additional hubs or switches
  • Up to 65535 devices with a maximum line length of 100 m between two devices
  • Supports almost all topologies (line, tree, star, ....)
  • Hardware-based mechanisms guarantee data consistency in the slave devices
  • Hardware-based device synchronization (distributed clocks) with a jitter of less than 1 µs
  • Optional cable redundancy through a transitionless switching  in case of a single device fault or cable break enables a very cost-effective improvement of system availability.
  • Definition of higher protocols: CAN application protocol over EtherCAT (CoE), Ethernet over EtherCAT (EoE), servo drive over EtherCAT (SoE) and file access over EtherCAT (FoE)
  • For improved interoperability a device profile is available

EtherCAT Implementation

  • An EtherCAT slave device requires specific hardware, which is available as stand-alone EtherCAT controller, FPGA-based IP core or microcontroller with built-in EtherCAT support.
  • An EtherCAT master does not require special interface hardware. It can be implemented based on a standard network controller.
