For many technological processes and information processing it is important to get certain results in a specific period of time. In this case the term real-time is used. What are real-time capable systems? How “quick” do they have to be and where are they needed? These are the questions we want to answer with this article.
Surely, the definition of Ethernet is well known to all the readers who once occupied themselves with connecting their own computers in a home network. More and more frequently the term Industrial Ethernet is used in connection with industrial systems. We will give you a deeper look into that topic here.
As an answer to the growing requirements of the modern automation engineering to the real-time capability of the bus systems and the high costs of the common bus components, several companies began to generate a real-time capable bus system. It is drawn up to the favorable standard components of the Ethernet-standards IEEE 802.3. One of these industrial-Ethernet bus systems is “EtherCAT”, which was initiated by the company Beckhoff Automation and is now further developed by the EtherCAT Technology Group.
