Industrial Ethernet - Definition and Advantages

Industrial Ethernet distinguishes itself from its office counterpart by being more robust to ensure reliable operation even in harsh industrial environments. Industrial Ethernet also has advantages compared to other industrial network technologies. However, here you can get the serial to Ethernet converters. 1. Speed: The fastest field bus works at a maximum speed of 12 Mb / s, industrial Ethernet is based on 100Mb / s and up to 10Gb / s. An advantage for demanding applications in response times. 2. Redundancy: In a field bus, all equipment in the same segment uses the same media. An anomaly in a piece of equipment, a connector, or the cable can affect the communication of all stations. With Ethernet, the media is not shared, an anomaly will only affect the station affected by the link. Technologies such as RSTP, HSP / PRP, or proprietary technologies such as MOXA's TURBO RING or Advantech's X-RING guarantee operation even after disconnecting the connection. 3. EMC: Ethernet is more robust than a fieldbus in terms of electromagnetic interference, and fully meets these requirements ( EN50155 standard and M12 connector for transport, R12 for electrical substations, etc.). 4. Protocol cohabitation: It is not possible to coexist PROFIBUS and MODBUS devices on the same cable even if both work with RS485. Thanks to Ethernet, it is possible to connect PROFINET and MODBUS-TCP stations on the same network, for example, while using the same network to consult a web page and send an email. 5. Access to IT technologies: Managed industrial Ethernet switches have a web server. A simple browser is all that is needed to configure or diagnose the device. The descriptive file (GSD, EDS ...) is stored on the device, you no longer have to worry about unsupported versions. Some devices can automatically send an email to report a defect or a maintenance operation, or power the sensors via POE. 6. Transparency: Ethernet technology makes access to the device much easier, even remotely, than if it were on a serial bus.
