The modular Industrial PC for mid-range control

Embedded Software

- TwinCAT on embedded Systems

- HMI solutions on embedded systems


Software

TwinCAT

• TwinCAT System• TwinCAT in embedded Systemen


TwinCAT : One Tool – all platforms

Bus-Controller Embedded PC IPC

Performance

Application Complexity

TwinCAT

• Systemconfiguration • TwinCAT Realtime Control

• PLC-programming IEC 61131-3

• Motion Control, NC-PTP, NC-I, CNC• Interfaces to scada via OPC / ADS


TwinCAT on PC (XP) Platform

•• pure pure software solution• does not modify Windows (NT / 2000 / XP / XPE)not bound to specific Service Pack

• not specific hardware required• changes standard-Windows into realtime operating system• tools for setup and programming on the PC

TwinCAT on a CE Platform

• optimal integration : one file NK.BIN contains CE-OS and TwinCAT• TwinCAT realtime : TwinCAT offers min. 50µs cycletime• TwinCAT tools : Remote setup (no tools local on CE)�� easy „XCOPY deployment“

TwinCAT Architecture: XPE / CE

� AdsDLL

� communication DLL for CE.NET

� Beckhoff OPC Server for CE


TwinCAT CE

� the TwinCAT „NT“ runtime is ported to Windows CE

� TwinCAT is a Win32 process in Windows CE

� all TwinCAT server are in the address space of the TwinCAT process

� programming of TwinCAT CE only through a separate desktop PC or notebook

� configuration of TwinCAT is also done through a remote (not on the device) System Manager

Structure of TwinCAT CE


Features of TwinCAT CE

Real-time is based on Windows CE capabilities

� lowest possible cycle time: 2 ms

� possibility to access from within the real-time tasks OS functions like

� network

� USB

� RS232

� hardware independent

� safe (protected) process in Windows CE


Features of TwinCAT CE

Same code as for TwinCAT „NT“

� supports all fieldbus systems

� full PLC functionality, 1 CPU with 4 tasks

� full NC functionality (limited axis number though)

� system configuration with TwinCAT System Manager


TwinCAT on Windows CE memory requirements

OS storage footprint:

� appr. 8 MB(includes IE 5.5, no MMP).NET compact framework will add about 4 MB

� attention: Increasing NK.BIN means also increased start-up time.

TwinCAT CE components storage footprint:

� around 4 Mbyte

�� with 16 Mbyte flash there is about 4 Mbyte left for customer application programs and data (without using the .NET compact framework).
