20. Features

21. Features?

22. Features
• Kernel Level Implementation

23. WinAC ODK

24. WinAC ODK

25. WinAC ODK
ODK
CCX - Custom Code eXtension
SMX - Shared Memory eXtension
CMI - Controller Management Integration

26. WinAC ODK
CMI
• Controller Management Integration (CMI) provides the
WinAC control panel functions for PC applications
Functions
• Connect to PLC
• Check Supported
Features
• Get/Set Attributes
• Mode (Run/Stop)
• LEDS
• AutoStart
• Memory Card File
• Register for Changes

27. WinAC ODK
SMX
• Shared Memory eXtension (SMX) exchanges data fast
between WinAC and the Windows application

28. SMX
Pros
• Fast!
• Simple to Implement
• Behaves like I/O
Cons
• Limited to 4KB Input and 4KB
Output
• Memory is Read-Only and
Write-Only
• No Data Consistency

29. WinAC ODK
CCX
• Custom Code eXtension (CCX) calls high-level language
routines from the WinAC control program

30. CCX
Pros
• Flexible
• Choice of Operation
 Synchronously
 Asynchronously
 Continuously
• Data Consistency
• Access to Data Blocks
Cons
• More Complex
• Slower

31. Windows vs Real-Time Core
Windows (dll) Real-Time (rtss/rtdll)

32. Languages
Windows (dll)
• C#
• VB
• C/C++
Real-Time (rtss/rtdll)
• C/C++
• Matlab Plugin (C++)

33. Advantages and Applications

34. Advantages and Applications
Totally Integrated
Device Integration
Database Access
.NET Framework
Web Services
Simplified Development

35. Totally NOT Integrated

36. Totally Integrated

37. Totally Integrated

38. Device Integration

39. Device Integration
USB devices/converters
• C/C++ rtdll/dll direct to driver

40. Device Integration
PCI Cards
• C/C++ logic to device
• Fieldbus Cards
• Hilscher, ESD, IXXAT
• Data Acquisition
• ADDI-Data, United Electronic Industries,
National Instruments

41. Device Integration
Bluetooth Anki demo
• C# communication logic <-> Bluetooth 4.0 USB dongle

42. Database Access
C# application with .NET Library or LINQ to SQL
• Log and/or retrieve complex data
• Can replace OPC Server with bridge to
database, or HMI plugins
• Multiple databases local and/or remote
• Different management systems (SQL,
Oracle, MySQL etc.)

43. .NET Framework
WPF/Win Forms/DirectX User Interface
• Completely Customizable
• Much higher development cost!

44. .NET Framework
Background Services
• WCF (Windows Communication Foundation)
• Allows remote connection by other
computers/processes
• System and File Access
• Complex Algorithms (math packages)
• Lookup Tables
• Large Memory Requirements

45. Web Services
• Headless ASP.NET website acting as an HMI
• Email Alerts
• Access to website APIs (google voice commands)
• Post to your twitter feed or share your machines status
on Facebook!

46. Simplified development
Wide support of windows drivers and applications
Large knowledgebase of “conventional” programming
languages

47. Simplified development
Easy conversion between existing projects and examples
Large pool of experienced developers and support

48. Simplified development
Separation of concerns
“DO_SOMETHING_AWESOME!”

49. Final Thoughts
DMC collectively has 10,000+ hours of experience working
on the WinAC platform.
It’s not the right solution for every project, but for the ones
it’s right for, it is so right.

50. If your PC can do it, so
can your PLC
…with WinAC!
