  7. Confidential SMART Factory Example Real-Time Interactive Communication Network Integration
  8. Confidential Integration with Enterprise Networks  Industrial Ethernet is the Common Platform • Interconnect devices, systems, and services • Transmit data for analysis, decision making and control Source: IEEE, 2014 SMART FACTORY Network Integration Enterprise Network Data Center
  9. Industrial Network Top 3 Challenges How do we… Simplify Installation & Deployment Minimize Error Probability Accelerate Error Discovery & Repair • Optimized Network Topology • Quick Mass Configuration • Device Durability • Network Redundancy • Cyber security Protection • Instant Active Alarm • Easy SCADA Integration • Remote Visualized Network Management Top Strategies
  10. SMART Factory Overview Secure Infrastructure Easy Centralized Management High Availability Robust Design Enterprise InTegration
  11. Confidential Factory is Vulnerable to Cyber Attacks Source: ICS-CERT 2013 Report, Region: the U.S. Cyber attacks may come from both outside AND inside factory Security
  12. Confidential Industrial Security Concerns PLC/IO Network Control Network Field Site / Factory Control Room Attack from public network Unauthorized connection Malfunctioning PLC Broadcast Storm • VPN function for data encryption • VPN server for dynamic remote access • Standard protocol: IPSec, L2TP, PPTP • Protect unauthorized connections to critical devices (PLC, RTU, DCS) • Isolated broadcast packets from malfunctioning device to entire network VPN tunnel Firewall Security
  13. Confidential Quick Mass Configuration  How do we reduce industrial network installation & configuration time? • Industrial Network Configuration Tools Client ITS System Integrator Current Solution Configure 20+ switches individually thru Web UI Pain Point Cost a lot of time and manpower to complete the configuration Sequential IP setting Redundancy VLAN … Smallest IP Current With Tools 10 times faster Management
  14. Confidential Visualized Network Management  How can maintenance engineers monitor & manage large scale industrial networks? • Visualized NMS Industrial NMS Enterprise NMS Design for… Industrial Engineers, Maintenance Engineers IT expert Connection Physical link (Down to “port”) Logical link Information Dispaly Visualization & List List Response Real time Periodic Management
  15. Network Availability/Reliability
  16. Network Topology Typical Enterprise Star Topology • Single point of failure • Long, costly wire/fiber runs Availability
  17. Network Topology Typical Industrial Ring Topology • No single point of failure • Reduced wiring costs Availability
  18. Confidential Build Up a Highly Reliable Communication Network  How do you choose the best redundancy for your application? Network switch/recovery time < Max. acceptable system downtime (Grace Time) Non time critical < 1 s Real Time < 100 ms Isochronous Real Time < 1ms Applications Non time critical applications Process Automation / Factory Automation Motion Control Grace Time Reliability Availability
  19. Confidential Optimized Network Topology Redundant Technology Type Mesh Ring Pros • Good reliability • High resilience • Standard protocol • Better performance and recovery time: ~millisecond level • Lower cost Cons • Slow recovery time ~second level • Limited Scale Available Technology RSTP General Fast Recovery (millisecond level) RSTP (20 ms @ 250 devices) Applied Environment Commercial Harsh environment, Industrial automation Backup Link Root Source: Moxa Industrial Preferred Availability
  20. Confidential Fast Boot-up is Critical to Increase Network Availability • PLC Boot-up Time*: ~20 sec • Most Switches: 40 sec ~ 1.5 min. •Industrial Ethernet Switches: 10 sec The time for switches to boot-up should be shorter than the PLC in order to improve the stability of the network * Siemens S7300, Allen Bradley CompactLogix 1769  Higher system availability, lower maintenance cost  Prevention of unnecessary alarm messages Benefits Ready ! Ready ! Ready ! Not yet! Availability
  21. Confidential Seamless Communications  Allows mobile devices (like AGVs) to be constantly connected to a wireless network  Reduces downtime and ensures all data gets through Availability
  22. Confidential Zero Packet Loss - Overview  Traditional Approach Vulnerable to Packet Loss • Single-RF devices • When interference disrupts data transmission, communication is disabled • Dual-RF devices • The secondary frequency is activated and data transmission resumes • However, packet loss will occur during the switching period. • Threshold setting will generate a “ping-pong” effect between two bands making the switching mechanism very inefficient Availability
  23. Confidential Zero Packet Loss: Concurrent Dual-Radio Technology  Eliminates the possibility of wireless interference • Duplicate packets and transmit via two independent modules simultaneously • When interference interrupts data transmission on the primary channel, concurrent transmission via the secondary frequency eliminates packet loss  Increase the throughput by reducing the number of resend request Availability
  24. Confidential Harsh Industrial Environments Robust Industrial Design
  25. Confidential Pipeline Monitoring System, Russia Moxa Inside Example: Switches Operating 24/7 in Harsh Environments Drilling System, Saudi-Arabia, Robust Industrial Design
  26. Confidential Integration with Control Level Network  SCADA Integration? • Plant field SCADA to control and manage devices through industrial protocols • Some switches support industrial protocols in order to integrate with SCADA • PROFINET • Ethernet/IP • Modbus TCP There are industrial automation specific switches that enable industrial protocols by default - Plug-n-Play! Systems Integration
