SIMATIC WinAC ODK (Open Development Kit)

Integration of special tasks

Description

PC-based solutions typically include technological tasks such as image processing, measured value acquisition and numerical controls. The new WinAC option Open Development Kit (ODK) allows flexible use of all PC resources from the control program via three different interfaces in orderto provide highperformance expansion of the PLC functionality. All the operating system functions and system resourcesof Windows are available to the programmer for this purpose, also providing access to external hardware and software components.

An ODK application is developed with a standard development environment for C-/C++ programming, such as Microsoft Visual Developer’s Studio. This provides the application developer with the familiar environment tailored to Windows applications. C++ programming knowledge is not required for integrating such applications into the WinAC control program. The ODK applications can be used like normal system functions in the STEP 7 program.To the top of the page

Area of application

WinAC ODK offers three interfaces for the following applications: 

  • Custom Code Extension Interface (CCX) for calling your own high level language programs from the WinAC control program
  • Shared Memory Extension Interface (SMX) for high-speed WinAC data exchange with Windows applications
  • Controller Management Interface (CMI) for integrating the WinAC Panel functionality into a Windows application


Custom Code Extension Interface (CCX)

ODK includes an application wizard and a class library for simple programming in Microsoft Visual Studio. The program running outside WinAC is developed with Visual C# – or with Visual Basic or Visual C# for Windows applications – and generated as DLL or Real-Time DLL. The DLL is called with the help of three systemfunctions (SFC 65001, 65002, 65003).
The C program can be executed in three different ways:

  • Synchronously, that is, processed as part of the PLC cycle 
  • Asynchronously, that is, started by the PLC program and terminated in the background
  • Continuously, that is, processed parallel to the PLC program


CCX and SMX applications can be executed both under Windowsas well as in the real-time core used by WinAC RTX. An additional tool from the manufacturer of the real-time core is required for developing real-time CCX applications. This allows diverse applications to be implemented.

Some examples include:

  • Connection of fieldbus cards to WinAC 
  • Integration of robot control software into WinAC 
  • Direct access to Windows file system 
  • Implementation of special communications protocols 
  • Complex calculations for control of the quality of packaging film

Shared Memory Extension Interface (SMX)

Via SMX, ODK supports the development of applications requiring data exchange between Windows applications such asVisual C++ and WinAC, as is the case, for example, in closed-loop control or image processing tasks.This data exchange is especially fast via the a dual-port RAM (DPR) or shared memory, accessed by both the external C++ programand the PLC program. ODK includes libraries for reading and writing to this DPR according to the polling method. From theviewpoint of the WinAC, the DPR represents a 4KB I/O area that can be accessed with load/transfer commands.

Typical applications of the SMX:

  • Connection of motion control systems 
  • Connection of systems for measured data acquisition and analysis
  • Transfer and backup of large volumes of production and quality data
  • Direct and high-performance integration of an order database
ODK
The Shared Memory Extension Interface (SMX) enables data exchange betweensoftware controllers and Microsoft applications

Controller Management Interface (CMI)

With ODK, the function of the WinAC Panels can be integrated into a Windows application
(see figure). For this purpose, the CMI provides the application with the following functions of the WinAC Panel:

  • LED status 
  • Start and stop of the WinAC 
  • Subsequent loading of programs
  • Integration of the WinAC Panel into an HMI application 
  • Remote operation of the WinAC
  • Implementation of specific user rights

WinAC Target

WinAC Target is a tool to simplify integration of MATLAB/Simulink algorithms into WinAC RTX.

MATLAB/Simulink, a software from The MathWorks, is frequently used in automation systems in the development and simulation of complex open-loop and closed-loop control algorithms.

Integration of MATLAB/Simulink algorithms with WinAC Target

MATLAB/Simulink is used to model and simulate processes and PID closed-loop control structures graphically. Simulink sub systems can be coded into C/C++. This code is then integrated into a WinAC ODK project and can be accessed and executed via DLL/RTDLL from the S7 program.

SIMATIC WinAC RTX F

SIMATIC WinAC RTX F – Fail-safe S7 software controller

SIMATIC WinAC RTX F is the fail-safe SIMATIC software controller for PC-based automation and permits both standard and fail-safe control tasks to be performed on the PC.

Area of application

SIMATIC WinAC RTX F permits simple implementation of safety systems on PC-based solutions, and satisfies maximum safety requirements and compliance with relevant standards: EN 954-1 up to Cat. 4, IEC 62061 up to SIL 3, and EN ISO 13849-1 up to PL e.

The fail-safe software controller is particularly suitable for automation tasks in which, in addition to standard and fail-safe control functions, parallel data processing and the integration of the user’s own technological functions are to be implemented on one platform and the openness of Windows is to be exploited.

To ensure the high performance of the complete system the latest PC technologies such as Dual Core are supported, in which one core is used for Windows applications and the other core exclusively for SIMATIC WinAC RTX F. The integration of C/C++ programs into the WinAC RTX control program provides access to all hardware and software components of the PC, creating an extremely flexible solution. The performance of WinAC RTX F is limited only by the PC platform used.

Apart from the software-only controller, particularly rugged and ready-to-run embedded bundles are also available, preinstalled with SIMATIC WinAC RTX F and Windows XP Embedded or Windows Embedded Standard. Whether on the basis of a modular embedded controller, a DIN rail PC or a Panel PC, the application ultimately determines the choice of hardware to be used.

Standardized engineering and the easy portability of the user software between the different solutions also contribute to the overall security of investment and flexibility.To the top of the page

Layout and function

Engineering
As in the fail-safe SIMATIC controllers, the engineering is implemented with STEP 7 and the Distributed Safety option package. This means that existing know-how can continue to be used.

Platforms

SIMATIC WinAC RTX F executes on all x86 hardware platforms with Windows XP Professional and is optimally matched to SIMATIC Industrial PCs. Especially when used on embedded PC platforms, such as the SIMATIC IPC 427C, the SIMATIC HMI IPC 477C or the SIMATIC S7-mEC with Windows Embedded Standard 2009, economical and extremely rugged solutions can be achieved. WinAC RTX F uses the main memory of the PC and offers a program backup in the data medium (e.g. HDD, CompactFlash card, SSD). Non-cyclic data, such as production parameters or recipe data, can be stored permanently on the data medium (e.g. HDD, CompactFlash card, SSD) of the PC with the help of system functions (SFC 82 – 84). In addition, all data can be held retentively in conjunction with an uninterruptible power supply (UPS).

Connection of the I/O

WinAC RTX F can control the distributed I/O not only via PROFIBUS, but also via PROFINET.

The I/O is connected via PROFIBUS DP at up to 12 Mbit/s via the integral DP interface of the SIMATIC IPCs or the embedded bundles. In addition, communications processors (CP 5611 A2/ 5613 A2) can also be used that support as many as four PROFIBUS lines with up to 500 slaves.

The connection to PROFINET is via Ethernet chipsets for PROFINET IO with RT:

Interface nameChipset
Intel® Pro/1000 CT Gigabit DesktopIntel®82574L
Intel® PRO/1000 PT dual port server adapterIntel® 82571EB

or via a CP 1616 (PCI) or CP 1604 (PCI-104) communications processor.

The SIMATIC IPCs or the embedded bundles feature an optional integrated PROFINET interface, while it is standard for the S7-mEC RTX F.

In addition, WinAC RTX F also supports the system function isochronous mode. With isochronous mode, high-speed, time-dependent applications such as closed-loop controls can also be implemented with distributed I/O. This means that in addition to the control job other functions can be integrated into a PC or smaller, more economical PCs can be used for the same job.
With the new version WinAC RTX 2010 further PROFINET functions are available e.g. shared device, media redundancy and webserver functionality.To the top of the page
