  2. Table of Contents • What is QVision? • Architecture • Features • Optional Modules

  3. What is QVision? • Software suite housing client, server, and database applications on standalone HMI hardware • Tied directly to an RTU processor or multifunction gateway • All applications are Windows based • Provides an easy to use local GUI • Device-level to station-level visualization • Touchscreen displays allows user to visualize substation data, note alarms and events, and check status points • Access Worldview and Plus Editors directly from a touchscreen HMI • Realtime alarm processing and historical data collection displays • Supports DNP and Modbus protocols

  4. QVision Additional Benefits • Points created and stored locally • Increased knowledge of system events and outages • Functionality to fit simpler customer requirements • Consistency of substation software • Editing and interaction of data points locally at substation • Space savings • Same support and professional services as provided with other software platforms • Consistent security features as provided on other software platforms • Decrease customer outage time

  7. Worldview User Interface • View local substation single-line diagrams directly from HMI • Interact directly with breakers and switches without needing to be at the master station

  8. Worldview User Interface • Visualize substation data and indications in real time directly from HMI

  9. Worldview User Interface • Load device specific schematics and cutsheets/protection schemes and RTU wiring diagrams directly to HMI

  10. Worldview User Interface • Check communication lines and LED indications of specific RTUs and other IEDS without needing to go into cabinet

  11. Alarm Processing • Use alarm view screen to view historical and real-time alarms • Acknowledge, block, and unblock alarms directly from HMI screen • Create audible alarms that can interact with buzzers and other devices

  12. Historical Data Collection and Display Publish real time or historical data directly to database Create pop-up windows to view data graphically directly on HMI Graphed data can be dynamically updated or assigned a fixed start time and duration

  13. Plus Editors • Edit database directly from HMI • View points lists and station trees to better sort database • Ability to download and work offline, make changes, and reupload • Import and export database points into MS-Excel spreadsheets for easier editing and copying

  14. Open Data Access Publish real-time SCADA data into a relational data base either on the SCADA network or remotely Data used to drive PC based applications- web displays, email notifications Interface is self-maintaining

  15. Event Data Recording • All status changes, analog changes, and operator control actions can be recorded to an online circular disk file • Request Event Data Views directly to HMI through Worldview • Status Bar located at bottom of every Worldview window

  16. Optional Modules- Command Sequencing • Define and execute programs that use database points as variables • Calculations, open-loop control sequences, closed-loop control • Programs can be triggered off a status change or through PMacros in WorldView • Templates allows users to develop complex custom calculations that can be used as subroutines in the command sequence

  17. Optional Modules- eAlarms • Get email notifications sent to specified recipients in response to alarms generated on QVision server • Emails contain date, time when alarm was generated, and 70 character alarm message text

  18. Optional Modules- Web Reports • Allows for transfer of SCADA data published into an SQL Server or Oracle database to be transferred to a web report displayed in a remote web browser QVision
