1. Ethernet as a field-network Renaud Barillère - CERN IT-CO

2. Factory Ethernet Field buses A typical control architecture DevicesPLCs SCADA EWS

3. Ethernet as a field-network Ethernet Factory Ethernet Field buses Devices PLCs SCADA EWS

4. Purposes of Ethernet as field- network Purposes: Run time data exchanges; Configuration of devices or PLCs; Remote maintenance. Remark about connections: Direct vs indirect connections

5. Ethernet hardware components The infrastructure components Standard LAN components or Industrial ones? Specific topology? The control components PLC modules; Bus couplers; Intelligent devices; Gateways (for field buses)

6. Ethernet software components The protocols 802.3, TCP/IP family Others? The libraries PLC libraries The tools Configuration/development Dedicated or open tools? Remote maintenance Web servers or dedicated tools.

7. A standard or n “standards”? Field buses: n “standards” Compatibility issues Interoperability issues Ethernet as field-network Are standards desired? De facto standard? New standard(s)?

8. What about security? Why Mistakes and attacks Where Infrastructure, PLC, Devices? How Passwords, IP address, others?
