4. Energy & Automation, Inc. Mining Technologies Why Remote Diagnostics? PM aids  Advanced diagnostic programs can monitor and test not only your electrical but also your mechanical systems. Immediate software updates  No down time, software can be downloaded and installed while the machine is operating. Keep the factory on your machine  Remote diagnostics let the factory experts help you troubleshoot immediately. No travel time is required. On line monitoring  Find out instantly how the machine operates. Monitor operation from the site office, the Siemens office, or any Internet connection.

5. Energy & Automation, Inc. Mining Technologies SiRAS and MIDAS The philosophy behind SiRAS Remote Diagnostics is MIDAS…

6. Energy & Automation, Inc. Mining Technologies MIDAS SiRAS and MIDAS Why MIDAS Normally measured data is in raw format. It is difficult to correlate data with real events. Data is often incompatible with programs like Microsoft Office, etc. Problems Our Solution Presents processed information in a clear, precise manner. Custom tailored user interface extract data relevant to special groups. Seamlessly integrates with Microsoft Office tools. Leverages expertise from Siemens factory based development and service personnel.

14. Energy & Automation, Inc. Mining Technologies Basic SiRAS Operation - Shovel Side Software allows to run all functions of the Shovel Maintenance PC remotely by remapping the I/O vectors (similar to “PC Anywhere”) Local Processor Executes Diagnostics Second Static Hard Disk w/ Diagnostic Application Programs & Diagnostic Cache Connected via internal bus SiBAS Control Rack SLOT PLC S7 Remote I/O on Shovel connected via Profibus HMI Touch screen Display Processor Shovel Maintenance Computer Connected via monitor interface (serial link) PC RACK Ethernet Wireless Ethernet Station Ethernet card Wireless Ethernet Shovel Access Point

16. Energy & Automation, Inc. Mining Technologies How does SiRAS work ? SiRAS Remote Diagnostics re maps the I/O vectors of the Shovel Maintenance computer to a remote computer. As a result :  All Machine Functions are available remotely. The remote operator sees the same as the local electricians.  Diagnostic software can be configured remotely, downloaded to the shovel, and activated by the local electrician. Then the remote operator can immediately analyze results.  The remote operator can communicate with the local electrician by printing messages on the screen. He can also manipulate the cursor to point out problems to the local electrician. The local electrician can ask questions using the same method.

17. Energy & Automation, Inc. Mining Technologies Internet Access  Any computer with an Internet connection and the right password can access the Mine Host PC which runs the Shovel Maintenance PC remotely.

21. Energy & Automation, Inc. Mining Technologies Standard SiRAS Hardware Package – One Time Cost Engineering Support  Consultation with local ISP personnel to optimize configuration of radio towers, and secure connection to the mine’s LAN, etc.  Complete turn key installations are available. On Shovel / Dragline  Maintenance computer upgrade for Remote Diagnostics including software  Shovel access point with wireless Ethernet station Ethernet Link  Wireless Ethernet repeater station for intermediate tower (requ. control power) In Mine Office  Mine office access point with wireless Ethernet station  Host computer for the mine office including software. This computer is the gateway to the shovel / dragline maintenance computer and is connected to the mine’s LAN and the Internet.

22. Energy & Automation, Inc. Mining Technologies MIDAS Service Packages – Monthly Fee Link Checking  The data link operation is checked daily via the Internet Basic Machine Monitoring  The machine is monitored daily. Any condition that might lead to failures is flagged and the mine is notified.  Summary and detail fault reports are created.  Motion faults trigger trace recordings which can be viewed for further analysis.  All significant control warnings (e.g. line voltage low) are summarized and available for trend analysis.  Statistics are compiled weekly / monthly and transmitted to the mine. Software Up dates  Unlimited software up dates Standard Package S Service ServiceS DDiagnosticsDDiagnostics MMonitoring AAnalysisAAnalysis
