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.
If you want to inform yourself about the topic of automation, you will need to learn more about fieldbus systems. The main reason for that is the increasing number of electronic components in nearly every area of life. But what exactly does that mean and where does the wide distribution of fieldbus systems come from? What is the assignment of the fieldbus and how do the communication networks operate? These and further questions will be answered in this blog post.
On today’s automation solutions, the number of electrical components continues to grow. The cabling of these electrical components requires a great effort, involving huge costs at the project planning and complex wiring schemes. For that reason, so-called “fieldbus systems” were developed, that transfer the data with help of only one single bus cable, which passes all field devices. Thus, the wiring effort and the weight could be drastically reduced. The “CAN-Bus” is probably the most famous fieldbus system, which mainly established a reputation in the sector of automotive engineering. The most important information among this topic is summarized in this article.
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.
By virtue of the increasing amount of automated systems, the importance of monitoring and controlling these complex systems rises, too. Obviously, the automated systems should be operated with minimum staff deployment. Therefore, it is necessary to offer tools to the operators for controlling the processes. “SCADA” is typically mentioned in this context, which integrates computer systems for exactly these monitoring- and controlling- tasks and relieves the operators. The definition of SCADA is given below, explaining, where it is used, and how it works.
