1 the Industrial Ethernet standard

2 is 100% Ethernet is Ethernet Ethernet is the established standard in the IT world for fast exchange of data (IEEE 802.3) is always full duplex simultaneous communication in two directions 100 MBit/s Controller As comparison: PROFIBUS One line to which all nodes are connected Performance directly dependent on number of nodes Master 100 MBit/s 100 MBit/s full duplex is always "switched Ethernet Slaves Switches connected into a line Distribution of network load can be influenced using topology Devices completely uses all possibilities offered by Ethernet Seite 2

3 The basic principle of Ethernet communication: nesting of data in message frames Layer The OSI layer model for structured communication Services 7 6 Application Presentation HTTP, FTP, SMTP, SNMP, etc. Web pages, mails, live pictures, network information, etc. 5 Session 4 Transport TCP, UDP TCP header Application data 3 Network IP IP header TCP header Application data 2 1 Data link Physical Ethernet, LLDP Ethernet header Ethernet header IP header header TCP header Application data Application data Ethernet trailer Ethernet trailer Maximum performance with retention of Ethernet standards Seite 3

4 Mechanisms for real-time communication in Separate channels for IO data and TCP/IP Performance and deterministic behavior through priority assignment of I/O data Openness for every type of Ethernet communication TCP, UDP, IP, etc. Integration of Ethernet devices in machines and systems (Webcam, network printer, etc.) Time scheduling Send cycle IO data TCP/IP Next cycle 1 2 n-1 n 1 2 n-1 n Open for any communication Real-time and standard on one cable = totally integrated uniformity Seite 4

5 This is my way provides more flexibility, efficiency and performance in your application Flexibility Efficiency Performance Tailor-made plant concepts Optimal use of resources Increased productivity Industrial Wireless LAN One cable for all purposes Speed Safety Device/network diagnostics High precision "With we are able to implement new machine and plant concepts, making us more competitive This is my way!"
