ETG officially supports EtherCAT G
December 2019
Fieldbus & Industrial Networking
The Technical Committee of the EtherCAT Technology Group (ETG) has accepted EtherCAT G as an addition to the EtherCAT standard. Moving forward, EtherCAT G, which extends EtherCAT technology to 1 and 10 Gb/s, respectively, will be supported and promoted by the ETG.
EtherCAT G was introduced by Beckhoff Automation in 2018 as an extension of the EtherCAT standard. Beckhoff recently presented the gigabit technology addition to the ETG, and after thorough review, the organisation’s Technical Committee accepted it. Dr Guido Beckmann, chairman of the ETG Technical Committee, explains: “EtherCAT is already the fastest industrial Ethernet fieldbus, and will remain so due to its special functional principle. With EtherCAT G, particularly data-hungry applications, such as machine vision and high-end measurement technology, can now also be integrated, which extends the range of applications.”
The well-known 100 Mb/s EtherCAT technology remains the proven solution for the majority of applications. However, EtherCAT G offers additional user advantages, especially in applications where particularly large amounts of process data must be transported per device. This can include, for example machine vision, high-end measurement technology or complex motion applications that go beyond the scope of classic drive control. Existing devices designed for 100 Mb/s can be seamlessly integrated into an EtherCAT G system, and EtherCAT G devices in a 100 Mb/s EtherCAT system behave like classic EtherCAT devices.

The central element of EtherCAT G is the use of EtherCAT Branch Controllers, which essentially fulfil two functions: On the one hand, they act as a node for the integration of segments from 100 Mb/s devices; while on the other, they enable parallel processing of the connected EtherCAT segments. This significantly reduces the propagation delay in the system, which increases system performance.
The integration of EtherCAT G is simple as the extension is fully compatible with the IEEE 802.3 Ethernet standard, and no software adaptions in controllers are required standard modes. “The advantages of EtherCAT are well known and include processing on the fly, comprehensive diagnostics, simple configuration and integrated synchronisation,” concludes Beckmann. “These attributes are of course fully retained when EtherCAT G is used.”
