DACHSview

     

visual Programming-Tool for Real-Time Applications

 

DACHSview is a function block based visual programming system for the cross-development of event-driven real-time applications.

 

The programming workbench is MS-Windows based and allows to create visual code for RTOS based real-time targets.  This code will be uploaded from the workbench into the real-time targets by a TCP/IP link. This link will also be used for online debugging and parametrization.  The workbench includes libraries for generic programming functions, and special RTOS related system functions like e.g. message passing primitives.

Example of an user-defined receive/reply component

Interesting options for DACHSview are libraries for visualization, data base handling, and fieldbuses: CAN, CANopen, PROFIBUS-DP, PROFINET, Ethernet Powerlink, INTERBUS, EtherCAT etc.

Integration with other I/O devices is possible.  Low-level I/O-devices can be developed easily because of DACHSview offers also access to the hardware-level.

Function blocks can be used in order to define new user-specific function blocks in a hierarchical way. No compiler is needed!

 

DACHSview, -SDL and -HDB is an ideal combination in order to realize SCADA applications in a flexible and optimized way.

some DACHSview examples are on a separate page.

 

 

DACHSview supports:

• event-driven DACHSview-applications according IEC61499
• optional program control according IEC 61131-3 for control applications
• integrated function blocks for visualization by DACHSview-SDL
• SQL data base SQLite by DACHSview-HDB
• excellent re-usability of function blocks means minimized development costs
• modular applications by integrating of multiple targets for one application
• hierarchically definitions of composited and application specific function blocks
• instanciation of composite function blocks
• import and export of function blocks
• upload of applications to the target
• networkwide cross-development of distributed control solutions
• message passing and other RTOS services
• dynamically extendable DACHS-view-Targets by C-Interpreter or Python
• simulation target for I/O hardware simulation
• support of semaphores
• TTF fonts
• OPC server and OPC library for OPC client development
• fieldbuses like PROFINET, EtherCAT, Powerlink, PROFIBUS-DP, CAN, CANopen, INTERBUS, etc.
• visual development of drivers for DAQ boards e.g via special function blocks with access to hardware interfaces
