  1. Remote Access In the 21st Century

  2. Telephone Exchange PSTN dial-up or leased lines Standard Analogue line (POTS) PSTN dial-up or leased lines Service Providers Network GSM Dial-up Legacy Remote Access

  3. Telecoms Provider Core IP Network VPN ADSL2+/VDSL ADSL2+, VDSL Fibre Connection to Central Routers VPN Service Providers Data Network 3G GPRS EDGE Today’s equivalent

  4. New Problems • Resistance to sales; • IT departments do not want VPN landing on their infrastructure • Perceived security risk • VPN’s perceived as complicated to configure and administer • IT technology outside of most engineers comfort zone or control • Reluctance to obtain new dedicated ADSL line • Internal support issues • New competition with “Made Easy” solutions • EWON • SECOMEA

  5. Market Place Drivers • National Telecoms networks (BT) is going fully digital • Some existing services are being discontinued • New PLC’s, RTU’s, I/O etc are typically connected via Ethernet • The amount of information or data required from each site is increasing • End customer pushing for lower maintenance costs cost • The need to reduce our Carbon Footprint and stop unnecessary journeys • Customer expectation, is for a quicker response to service issues • Service organisation, operational cost reductions

  6. The solution WestermoConnect

  7. WestermoConnect WestermoConnect VPN Concentrator Access via 3G, ADSL,VDSL or LAN router High Security VPN Internet Connect from anywhere with access to the internet 24/7 connectivity or on demand ping ping Simple to install, free Client software

  8. Connectivity

  9. Access via 3G, ADSL,VDSL or LAN router WestermoConnect VPN Concentrator High Security VPN Always on connection from corporate LAN Via corporate Router Internet Connect from anywhere with access to the internet 3G Cellular network ping ping Simple to install, free Client software 24/7 connectivity or on demand

  10. Connectivity Options

  11. Connectivity VDSL/ADSL ADSL 24/7/365 always on or Traffic triggered on demand DR-260/DR250 For connectivity options on BT Infinity/VDSL contact Westermo

  12. Connection methods Ping/UDP or TCP message destined for remote server On Demand Communication cease between client and host. VPN times out and connection drops

  13. Connectivity Cellular 24/7/365 always on or SMS triggered on demand MRD-310/330 24/7/365 always on, SMS triggered or traffic on demand MR-210/260/270

  14. Connection methods SMS Message controlled VPN SMS VPN CLOSE SMS VPN OPEN Customer operated key switch or contact on PLC VPN closes in response to SMS message VPN Opens in response to SMS message

  15. Connectivity LAN to LAN 24/7/365 always on Future developments will enable control of VPN for on demand Customers own IT infrastructure Even Viper

  16. Topologies Many to Many All sites and client can exchange data communicate with each other

  17. Topologies One to Many Clients can exchange data with any site

  18. Legacy Serial Support

  19. Serial Legacy Support • WestermoConnect will support serial communications; • All routers are equipped with serial port’s • Legacy serial protocols supported DF1, MODBUS, Unitelway, Melsec • Serial IP or similar can be used on Host machines • Point to Point serial connections between routers (pseudo Leased lines) • Point to Multipoint serial connections (pseudo Multidrop Leased Lines) • EDW-100/120 will allow more serial ports to be connected

  20. Benefits • PLCs, RTUs etc are unaware of the change of media • No changes are required to the PLC or RTU firmware or software • Legacy SCADA, DCS or logging software will not require upgrades or replacement • Extended working life of legacy systems • Migration path to IP based solution built in • Old and new systems can be run in tandem Ethernet Ethernet

  21. WestermoConnect system resilience
