Visualisation and Analyis on a Siemens Sinumerik 840DSl by the use of OPC Server

We are looking for implementing a Yield-Point-Detector test in a stretchbending machine. Basic configuration: - Control: Siemens 840D Solution Line - Industry PC with Windows 7 or Windows 10 in the machine - Machine with CNC controlled arms - Connection to machine data and "real-time" details by the the use of OPC Server from Siemens and/or DDE Server for older controls (Option) Mechanical machine basics: Two arms can pull material in a straight line. The arms are closed loop position controlled. Force can be read out in realtime. By moving a fixed speed and reading the graph a change in the angle due to material properties can be observed. Once the angle changes, the operation must stop and a number (Required force to cross the Yield point) must be given as a parameter. - Available Data: Realtime Force, Position. Basic requirements: - Flexible axes assignment for use of different machines. - Generation of a graph to analyse material properties. - Finding of Yield point where the material changes from elastic to plastic deformation - possible of stretching until material tearing to fully analyse parts - Storing of results in PDF/JPG - Comparison of results - Analysis by cursor in the graph display - Password generated settings screen, locked software with hardware (Network card e.g.) - Intergration of Logo, instructions, etc - Standalone possibility to analyse traces made with CNC trace program - Communication of CNC program and analysis software can be done by R-Parameters which are accessible by OPC Server. Tests can be conducted over remote maintainance on a test control, which is equipped with OPC Server, same software version than production machines, sumulated axes. This control is available 24/7 by Teamviewer access A basic and working version programmed in TCL can be used. Sourcecode is available.
