WinAC ODK

ODK

CCX - Custom Code eXtension SMX - Shared Memory eXtension CMI - Controller Management Integration

WinAC ODKCMI

• 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

WinAC ODKSMX

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

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

WinAC ODKCCX

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

CCX

Pros• Flexible• Choice of Operation

Synchronously Asynchronously Continuously

• Data Consistency• Access to Data Blocks

Cons• More Complex• Slower

Windows vs Real-Time Core

Device Integration

Device IntegrationUSB devices/converters

• C/C++ rtdll/dll direct to driver

Device IntegrationPCI Cards

• C/C++ logic to device• Fieldbus Cards

• Hilscher, ESD, IXXAT• Data Acquisition

• ADDI-Data, United Electronic Industries, National Instruments

Device IntegrationBluetooth Anki demo

• C# communication logic <-> Bluetooth 4.0 USB dongle

Database AccessC# 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.)

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

.NET FrameworkBackground 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

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!

Simplified development

Wide support of windows drivers and applications

Large knowledgebase of “conventional” programming languages

Simplified developmentEasy conversion between existing projects and examples

Large pool of experienced developers and support

Simplified development

Separation of concerns

“DO_SOMETHING_AWESOME!”

Final ThoughtsDMC 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.

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