The use of Industrial Ethernet is becoming more and more widespread, and the industry is becoming more familiar with Industrial Ethernet. In previous articles, I have had many introductions to industrial Ethernet. In this article, I will elaborate on the 6 major types of industrial Ethernet. If you are interested in industrial Ethernet, you may wish to continue reading.
At present, the widely used industrial Ethernet standards include the following six types:
(1) MODBUSTCP/IP
Schneider Electric has adopted Industrial Ethernet-based collaborative automation solutions as its development strategy. MODBUS systems can be easily upgraded to MODBUSTCP/IP without the need for users to reinvest in the original system. In the case of MODBUS serial connections, e.g. RS485, corresponding products can be provided to easily update or upgrade existing MODBUS systems to MODBUSTCP/IP. If other networks are used, the corresponding gateway can also be used to integrate or upgrade to an Ethernet system.
(2) Ethernet/IP
Ethernet / IP is an industrial automation applications for industrial application layer protocol, is the main push ControlNet fieldbus Rockwell Automation for Ethernet into the field of automation to study the creation of the Ethernet industrial protocol. It is built on top of the standard UDP / IP and TCP / IP protocols, the use of fixed Ethernet hardware and software, for the configuration, access and control of industrial automation equipment to define an application layer protocol. Ethernet / IP protocol by the IEEE802.3 physical layer, data link layer standard protocols and control and information protocols, such as CIP, three parts.
(3) EthernetPOWERLINK
EthernetPOWERLINK is a standard Ethernet medium to solve the industrial control and data acquisition in the field of data transmission of real-time technology. EthernetPOWERLINK has Ethernet's high-speed, open interfaces, as well as CANopen in the industrial field of good data definition of SDO and PDO, in a sense that POWERLINK is the CANopen on Ethernet, the physical layer, data link layer using the Ethernet medium, while the application layer retains the original SDO and PDO object dictionary structure.
(4) PROFInet
PROFINET was launched by PROFIBUS International Organization, which is a new generation of automation bus standard based on industrial Ethernet technology. PROFINET encompasses such current hot topics in the field of automation as real-time Ethernet, motion control, distributed automation, fail-safe, and cybersecurity, etc., and as a cross-supplier technology, it is fully compatible with the industrial Ethernet and the existing fieldbus (such as PROFIBUS) technology, and it can be used as a cross-provider technology to ensure that it is fully compatible with the existing fieldbus (such as PROFIBUS). PROFIBUS) to protect existing investments.
(5) SERCOSIII
Sercos (SerialRealTImeCommunicaTIonSystem) has been popular in the field of factory automation applications (suitable for mechanical engineering and construction) for 25 years. sercsIII is a third-generation protocol that was developed in 2003. This highly efficient and deterministic communication protocol integrates the real-time data exchange of the Sercos interface with Ethernet.SERCOSIII is a combination of the proven communication mechanisms of SERCOS and Industrial Ethernet, which has both the real-time characteristics of SERCOS and the characteristics of Ethernet.
(6) EtherCAT
Originally developed by Pepperl+Fuchs Automation, EtherCAT sets a new standard for real-time performance and topology flexibility, and at the same time meets and even reduces the cost of fieldbus use. features include high-precision device synchronization, optional cable redundancy, and a functional safety protocol (SIL3).
