DACHSview-SDL

DACHSview-SDL is the answer on increased complexity as well as increasing costs of development for industrial automation applications.

DACHSview-SDL is an innovative IDE-tool which is based on a graphical function block language and covers all aspects of today’s industrial automation. DACHSview-SDL applications are data flow- and function block oriented and are developed within an uniform programming environment

Every static and dynamical element is changeable at Runtime. That means that the dimension, color, scale, as well as the color of all elements like needle, ticks of the scale etc. are also changeable dependent of the displayed value.

in this application the needle changes its color dependent of the scale value

3D Applications 

DACHSview-SDL comes with Function Block Libraries for:

• 2D graphics: calls of the libraries SDL and SDL-Gfx, SDL_ttf, TinySDGL and Agar as pre-defined function blocks (FBs) incl. higher level FBs for easy handling of complex visualization tasks,
• 3D graphics: OpenGL (SDGL)
• Standard controls: GUI buttons, control- and input-elements, etc.
• SQL, historical data base: SQLite for extending DACHSview-SDL for processing mass data or for SCADA requirements
• International fonts: TTF support

 Options, FB Libraries for:

• Fieldbuses - for processing I/O-data with, EtherCAT, Ethernet POWERLINK, PROFINET, Modbus, PROFIBUS-DP, CAN, CANopen, INTERBUS, etc.
• additional interfaces like OPC and TCP/IP-based middleware (SDL-net, PVM e.g.)
• on request: converting C-APIs for devices to FB libraries for DACHSview

All these FBs are provided by the libraries of the MS-Windows based Workbench for the programming tool DACHSview-SDL, and are included in a specific DACHSview-SDL Target for QNX Neutrino RTOS 6.x.   

Important features of DACHSview-SDL:

• minimized complexity by abstraction of details of interfaces in high-level-function blocks
• higher efficiency in development and shorter time to market because of developers have no longer to care for details of the system
• by mouse-click definition of complex and re-usable GUI-components, based on pre-defined and user-defined function blocks.
• hierarchical definitions of composite and application specific function blocks
• easy reuse by instantiation of library- and composite function blocks
• minimized coding errors by code-reuse 
• free graphical programming combined with Soft-PLC tasks
• access from a single pixel up to a complex widget or virtual instrument
• buttons, control- and input-elements

• TTF fonts

• development of control applications by access to hardware interfaces, fieldbus systems and libraries for graphical elements
• processing in system threads and internal managed threads according IEC 61131-3
• blocking function blocks in system threads (IEC 61499-processing), therefore response time on real-time events in microseconds and not in milliseconds! 
• access to shared-memory, I/O ports, interrupts, and fast message-passing
• seamless data flow between subsystems like SQL data base or fieldbus-IOs like EtherCAT, Ethernet PowerLink, PROFINET, Modbus, PROFIBUS-DP, CAN, CANopen, INTERBUS, etc.
• development of device drivers by hierarchical defined function blocks
• C-applications can even be integrated by message-passing. 
• historical data base (function block library for SQLite) for extending DACHSview-SDL for processing mass data or for SCADA requirements
