Embedded PC 6

• Windows XP Embedded is the desktop OS for powerful

embedded systems

• Windows XP Embedded is Windows XP broken into more

than 10.000 components

• Target Designer and Analyzer helps setting up a system
• Windows XPE is scalable from 8MB to 1GB
• Since XP Embedded is binary compatible to Windows XP :
• Standard TwinCAT works on XP Embedded
• Install Third Party Software

Windows CE : Windows Compact Edition

Embedded PC 9

Windows CE

Features: Bluetooth TCP/IP stack und WinSock 2.0 RAS server remote desktop protocol (RDP) to terminal server UPnP device host und control point secure socket layer (SSL) Direct3D, DVD, Direct Music APIs Internet Explorer 5.5 for CE + free Web Server supported CPU families: ARM, StrongARM, XScale MIPS (PowerPC support discontinued) Hitachi x86

Embedded PC 10

General advantages of Windows CE

Win32 API 32 bit multiprocessing + multithreading protected processes 256 thread priorities (cmp. NT = 15 priorities, TwinCAT = 64 priorities) small resource footprint, smallest CE fits in 200 kb ROM/Flash genuine real-time capability starting with version 3.0 InstantOn capable e.g. X86 boot in approx. 10 s Embedded Visual Studio development tools C++ Compiler Visual Basic multitude of processors supported most of the OS source code is disclosed to user low license costs

Embedded PC 11

Restrictions of Windows CE

• maximum 32 processes, but virtually unlimited threads
• maximum 32 MB address space per process
• not binary compatible to desktop Windows (W9x, WNT, W2K, WXP)
• desktop software will generally not function on a CE device
• driver support for PC hardware is not so good
• applications can run in full screen mode only
• no MDI applications possible

Embedded PC 12

Development tools for Windows CE

Microsoft Visual Studio.Net compiles all languages like C++, C#, VB to managed code (MSIL) Embedded Visual C++ 4.0 cross-compiler for all “CE”-CPUs development environment runs on WNT, W2K, WXP (is almost identical to Visual Studio for desktop) entire tool-suite can be downloaded for free from the Microsoft Website Third party runtimes for several SCADA packages NS-Basic, interpreter pocket C, command line compiler

Beckhoff Image : CE

Tool "CxConfig" key tool to offer most important diagnostic / configuration Information / Configuration

• Image Version
• TwinCAT Version
• RAS Configuration (User / rights)
• Screen resolution
• FTP Server (Path / user / rights)
• SNTP Server (Simple Network Time)
• Audio activation
• Pre settings for keyboard

(NumLock-Key etc)

Embedded PC 15

Windows CE : RDP / Remote Display

RDP : Remote Desktop Protokoll

• Remote control of XP-PCs at CE device
• scalable :

view / mouse / sound / printer new : configure multiple PC connections and swap with hot-keys

Remote Display

• Remote control of CE device at PC

Which TwinCAT components are available

• n CE?

all TwinCAT runtime servers PLC, NC (Motion Control) TwinCAT system components AdsDLL (now available fully featured for CE) TcScript (for ADS access from Java ) TwinCAT components NOT being ported to CE: System Manager, PLC Control, Scope

TwinCAT and XP Embedded

Windows XP Embedded is the desktop OS for powerful embedded systems Windows XP Embedded is Windows XP broken into more than 10.000 components target designer and analyzer helps setting up a system Windows XPE is scalable from 64 MB to 1 GB since XP Embedded is binary compatible to Windows XP:

• standard TwinCAT works on XP Embedded

Embedded PC 18

When to use Windows CE?

Decision criteria:

• very low system footprint
• quick power on
• no rotating storage media, no cooling fans
• limited HMI and automation function requirements

USE A WINDOWS CE BASED CONTROLLER !

Embedded PC 19

When to use Windows XPE?

Decision criteria:

• medium system footprint
• quick power on
• no rotating storage media, no cooling fans
• extensive HMI and automation function requirements

USE A WINDOWS XP EMBEDDED CONTROLLER !

Embedded PC 20

When to use Windows XP?

Decision criteria:

• allow rotating storage media and cooling fans
• extensive HMI and automation function requirements
• ffice and general computing functions (word, excel, databases …)
