Application Programming Interface

Beside of the application software TransAS several programming interfaces are available for connecting customer specific software with TraNET devices or TPCX modules. Basically two types of interfaces are available:

  • Over the TpcAccess API full hardware access is possible: channel hardware settings, measurement controlling, data readout etc. TpcAccess is also used by TransAS.
  • For accessing functionality of TransAS the COM (Component Object Model) interface of TransAS can be used. Thus access to scalar calculation and data saving methods are possible.

TpcAccess API

TpcAccess API is based on a client/server architecture where the TpcAccess API represents the client. The server software is installed together with the TPCX hardware driver (TpcServer). Several clients can be connected to one server. All parameters are managed on the server side and a messaging service keeps all connected client up to date. TpcAccess makes no difference between local or network connection. This allows developing flexible applications which can be run on local machines or be used as remote control application. As the connection is made over TCP/IP easy connection over Internet is possible. TpcAccess is a C++ DLL. A C# wrapper is available, examples for C++, C# and Visual Basic on demand.

COM / ActiveX

Microsoft COM (Component Object Model) technology enables software components to communicate each other. The TransAS COM interface allows access to scalar calculation, cursors placing as also data saving methods. COM enables also access from EXCEL.
