2. “Painless” Continuous Operations System Conversions By: Advanced Traffic Control, Inc. Coconut Creek, Florida

3. Need To Replace Your Legacy System? Convert With Virtually No DowntimeConvert With Virtually No Downtime HOW? Advanced Traffic Control, Inc. With Advanced Traffic Control, Inc.

4. “Painless” Conversions Goals –Minimize System Downtime –Maximize Fail-Back Options To Allow Comprehensive Testing –Minimize Critical Timeframe So That Conversion Can Be Done Over As Long A Period Of Time As Needed Solution – Advanced Traffic Control, Inc.!

5. We’ve Done This Before! Alcoa Aluminum Point Comfort – Modcomp to Dec Alpha with VMS Hampton Roads Bridge Tunnel – Legacy to Distributed PCs with virtually NO downtime Elizabeth River Tunnel – Legacy to Distributed PCs with virtually NO downtime Monitor Merrimac Memorial Bridge-Tunnel – Legacy to Distributed PCs with Virtually NO Downtime

6. What is NOT “Painless” Converting proprietary code from a proprietary system. –Converting functionality that you can now purchase as a component (such as we see in modern general purpose Human Machine Interfaces). –Converting custom communications code rather than using newer communications technologies that are available off-the-shelf. –Converting monolithic designs to modern client/server architectures.

7. Two Types Of Data To Handle Data only contained in an I/O Stream –Camera Control Data (PTZ control) –Raw Field Controller Data API or Open Standard Accessible Data –ODBC Databases –Legacy Databases (including Real-Time) –Any Global Data Accessible To A Program

8. What About Direct I/O Devices? Some legacy applications generate their own field protocol, not going through ANY common API accessible data. –Camera Controls Real-time field data –Device States, Status –Traffic Monitoring Data

9. Directly Controlled Device ATC Universal Protocol Driver Off The Shelf OPC Based Control System A Switch or Data Tap Will Allow Testing and Parallel Operations ATC Smart Switch works great! Switch/ Data Tap

10. Caution! If you directly map all of the data in the field equipment into your replacement system right away, you might not be able to keep the systems synchronized so that you can go back and forth during testing without effecting the motoring public. It’s better to get whatever data you can from the existing system. That way it’ll be the same.

11. API or Open Standard Accessible Data This Data Can Be Moved To Another System By Converting It To A Standard Format (OLE for Process Control – OPC) –Open Database Connectivity (ODBC) databases can be converted through standard relational database techniques and accessed via networking –Create a simple program using API Subroutines or accessing data in memory resident global common region to send and receive data –Use the ATC Universal OPC-to-Legacy Solution to convert the data to OPC

12. OPC is OPC Convert to Live Data Later If data arrives in the new system as OPC data, the system doesn’t care where it came from. Extracting data from the I/O stream is simple using the ATC Universal OPC-to- Legacy Solution, so doing it later is not a major impact.

13. Existing Field Equipment Raw Data ATC Universal OPC-to-Legacy Solution Add Data Transfer Program To Send Data To The New System Off The Shelf OPC Based Control System API data transfer program Legacy System NO Changes to Operations - NO Changes to Operations OPC Data

14. Develop New Operator Screens Using OPC Tag Names HMI API data transfer program ATC Universal OPC-to-Legacy Solution Off The Shelf OPC Based Control System Existing Field Equipment Raw Data Legacy System Data Tap OPC Data

15. Train The Operators On The New Operator Screens (Legacy System Stays Available) API data transfer program ATC Universal OPC-to-Legacy Solution Off The Shelf OPC Based Control System Existing Field Equipment Raw Data Legacy System Data Tap OPC Data

16. Move Operations, Keeping Old Consoles As Backups API data transfer program ATC Universal OPC-to-Legacy Solution Off The Shelf OPC Based Control System Existing Field Equipment OPC Data Legacy System Data Tap OPC Data

17. Move Control Logic from Legacy System to New System I/O Processes Control Tasks API data transfer program ATC Universal OPC-to-Legacy Solution Off The Shelf OPC Based Control System Existing Field Equipment OPC Data Legacy System Data Tap OPC Data

18. Move I/O Points And Controllers To New System Existing or New I/O Field Communications Field Equipment Control Tasks API data transfer program ATC Universal OPC-to-Legacy Solution Off The Shelf OPC Based Control System OPC Data ATC OPC To NTCIP Legacy System AS TIME ALLOWS OPC Data

19. Remove Unnecessary Components – The OLD System! HMI Field Equipment Off The Shelf OPC Based Control System Legacy Controllers Control Tasks ATC Universal OPC-to-Legacy Solution OPC Data NTC/IP Controllers NTC/IP to OPC Driver OPC Data

20. HMI Field Equipment PC 1 Legacy Controllers Control Tasks ATC Universal OPC-to-Legacy Solution OPC Data NTC/IP Controllers NTC/IP to OPC Driver OPC Data PC 3PC 2 PC n

21. ATC Tools For Conversion ATC Universal OPC-to-Legacy Solution –Serial or TCP/IP based packet protocols –Packet structure defined by the user ATC NTCIP to OPC Driver –NTCIP to field equipment and OPC data to the system ATC Smart Serial Switch –Will allow switching of serial lines automatically –Onboard microprocessor can handle legacy synchronous protocols and custom protocol conversions.
