EtherCAT integreres nu i ARM-baserede processorer

Texas Instruments understøtter som det første firma nu EtherCAT teknologi i ARM-baserede processorer (in english).

Texas Instruments (TI) is the first semiconductor company to license Ethernet for Control Automation Technology (EtherCAT)for its ARM-based embedded processors in TI's  upcoming Sitara ARM microprocessors (MPUs) planned for the beginning of the fourth quarter of 2011 and in further processor platforms beginning in 2012.
 
EtherCAT technology is based on the principle of fast processing on the fly.  EtherCAT messages are passed from node to node and processed while they are passed, which improves speed and efficiency in industrial systems. Overall industrial application performance is also improved with shorter reaction times, enabling increased operational efficiency. 


EtherCAT uses the standard IEEE 802.3 frames and physical layer.  No external switches or hubs are necessary because the EtherCAT slave controllers forward the frames automatically.  Most devices embed two RJ-45 ports, which are commonly utilized data ports for Ethernet connections.   Auto-configuration of the EtherCAT technology is supported.  No manual address setting is required and no network tuning is needed.

With the use of standard cabling and no external hubs or switches needed, this lowers the EtherCAT technology costs.  There are also lower configuration costs with the auto-configuration support.
 
- The EtherCAT Protocol technology sets new standards for real-time performance and flexibility which is critical for TI embedded ARM devices geared toward the industrial market. As a leading Industrial Communication protocol the growing popularity of EtherCAT in industrial drive and I/O applications, is based on its robustness and simplicity allowing master and slave controllers to communicate with each other without a host computer in high-noise industrial environments, says Matthias Poppel, Director for Embedded Processing at TI, EMEA.

- The TI approach to EtherCAT with the programmable real-time unit (PRU) on TI’s ARM-based processors allows for flexible implementation that can more easily adapt as industrial standards evolve over time. Real-time control and –communication become available on a single chip.

- A market leading microcontroller company integrates an EtherCAT interface in several product lines: this turns EtherCAT into a mainstream technology also beyond the automation world! We are thrilled about this milestone development which will open entirely new markets for EtherCAT. I am convinced that this will help EtherCAT to establish a strong position in a wide range of embedded applications and further accelerate the adoption of EtherCAT in the automation market, says Martin Rostan, EtherCAT Technology Group Executive Director.
