1. Remote Connectivity Solutions PSTN, ISDN, GPRS, EDGE, 3G, ADSL, LAN Which connectivity to use ? A solution based approach

2. > Remote Connectivity Solutions 2 markets Machine Builders Infrastructure/Utilities 2 1

3. > Remote Connectivity Solutions 2 different needs Connection on purpose: 1.Connection temporary oriented 2.Simplex communication: machine/RTU ->user 3.Or… full duplex (bi-directional) communication: user-machine/RTU-user Or persistent connection 1.Duplex communication 2.And asset/site-to-site extranet 2 1

4. > Remote Connectivity Solutions 2 different technologies Old style modem like: dial-up (Point-to-Point connections over telephone network)  Embedded PSTN, ISDN or GSM data modem Purely IP though Internet network  Embedded PSTN, ISDN, GPRS, EDGE, 3G, ADSL modem or connection through LAN 2 1

5. > Remote Connectivity Solutions Remote Connectivity Matrix PersistentTemporary, on purpose Simplex, From RTU * Duplex, Remote Access Connection duration Connection direction RTU = Remote Terminal Unit = eWON

6. > Remote Connectivity Solutions Solutions for Machine Builders PersistentTemporary, on purpose NA Connection duration Remote Maintenance= 1.Remote PLC Programming 2.Remote Diagnosis 3.Predictive Maintenance NA RTU = Remote Terminal Unit = eWON Simplex, From RTU * Duplex, Remote Access Connection direction

7. > Remote Connectivity Solutions Modems for Machine Builders PersistentTemporary, on purpose NA Connection duration Dial-up PSTN or ISDN Internet PSTN Mobile: EDGE, 3G ADSL Through LAN NA RTU = Remote Terminal Unit = eWON Simplex, From RTU * Duplex, Remote Access Connection direction

8. > Remote Connectivity Solutions Solutions for Infrastructure/Utilities PersistentTemporary, on purpose Alarms Management Remote Monitoring = data collection & crunching, data logging, scripting, …) Remote Metering = same as rem. monit. wo PLCs Connection duration Remote Management= 1.Remote Control + 2.Remote HMI and/or 3.Remote Monitoring Extranets (Permanent IP gateways) NA RTU = Remote Terminal Unit = eWON Simplex, From RTU * Duplex, Remote Access Connection direction

9. > Remote Connectivity Solutions Modems for Infrastructure/Utilities PersistentTemporary, on purpose Dial-up PSTN, ISDN Mobile: GSM data Internet Mobile: GPRS Connection duration Dial-up PSTN, ISDN Internet Mobile: GPRS,EDGE, 3G PSTN Internet Mobile: GPRS,EDGE,3G ADSL NA RTU = Remote Terminal Unit = eWON Simplex, From RTU * Duplex, Remote Access Connection direction

10. > Remote Connectivity Solutions Modems: cost structure Dial-upInternet PSTN, ISDN Cost is time & distance dependant Cost is time dependant GSM Data GPRSNA Cost is data dependant or flat EDGENA 3GNA ADSLNA LANNA Modems: technology review

11. > Remote Connectivity Solutions Modems: pros & cons Dial-upInternet PSTN, ISDN Easy setup. Worldwide availability Cheaper & better (because local calls) GSM Data NA GPRSNA Easy setup, worldwide availability and Plug & Play with EDGENA 3GNA ADSLNA LANNA Modems: technology review

12. > Remote Connectivity Solutions Data transfer rates Dial-upInternet PSTN, ISDN PSTN 56kbps ISDN 128kbps GSM Data Max 14kbpsNA GPRSNA 32-48 kbps EDGENA Max 384 kbps 3GNA 8 – 10 Mbps ADSLNA Max down 24Mbps Max up 1Mbps LANNA Modems: technology review

13. > Remote Connectivity Solutions Telephone network / ISDN Dial-up connections Establish a Point-to-Point communication (IP communication) between your PC and industrial LAN Route all IP messages from the PPP connection to the LAN Standard IP routing capabilities such as IP forwarding, Firewall: NAT, Filtering, Access control Requirements: 1.eWON 2001/4001 with embedded PSTN, ISDN, or GSM modem Technology review # phone number IP 202.0.0.240 IP 202.0.0.1

14. > Remote Connectivity Solutions Internet connections Establish Internet communication through call-back mechanism, with IP address publication Using eWON embedded PSTN, ISDN, GPRS/EDGE/3G modem All devices with Ethernet & TCP/IP or serial protocol behind eWON can then be reached 1.eWONs 2101/4101, eWON 2005CD/4005CD, eWON 2104/4104 Internet Service Provider Tunnel IP address IP source Dyn-DNS  Technology review IP dest

15. > Remote Connectivity Solutions Internet connections: the ideal scenario Requirements : 1.Internet Service Provider (ISP) on the eWON side should provide Public IP address and 2.Firewall (ISP) should be transparent to the VPN connection Internet Service Provider VPN Tunnel IP dest (public IP) IP source Technology review

16. > Remote Connectivity Solutions Internet Customer LAN IP dest Internet with Talk2M Why Talk2M ? 1.Very often, the requirements for the ideal solution are not or difficult to meet 2.Or we want to access eWON connected to the Internet through the local LAN  In most of the case, the firewall blocks all incoming traffic  In conclusion, only outgoing traffic is allowed (e.g. browsing HTTP or HTTPS website) IP source Technology review

17. > Remote Connectivity Solutions Internet with Talk2M Talk2M resolve these common connection problems in 3 steps 1.eWON is connected to Talk2M (VPN link) 2.User is connected to Talk2M (VPN link) 3.Talk2M interconnects the 2 VPN links All devices with Ethernet & TCP/IP or serial protocol behind eWON can then be reached Technology review Internet Customer LAN IP Dest IP source VPN Tunnel VPN link User

18. > Remote Connectivity Solutions Which remote access solution/tool ? PersistentTemporary, on purpose NA Simplex, From RTU * Duplex, Remote Access Connection duration Connection direction NA RTU = Remote Terminal Unit = eWON eSync Connect,

19. > Remote Connectivity Solutions Which eWON model ? Non-permanent connection (on purpose) Persistent connection PSTN / ISDN GSM DATA 2001/4001 GPRS, EDGE, 3G 2101/4101 Through LAN 2005CD/4005CD ADSL 2104/4104
