Kithara RealTime CANopen

CANopen® in real-time for Windows

Kithara RealTime CANopen is a modular real-time extension for Windows operating systems, with focus on real-time automation with CANopen®.

In order to gain “hard” real-time capabilities, it is necessary to run the application code in kernel mode of the system. This is provided by the software.

The required programming languages must be able to generate native x86 or x64 machine code, e. g. C/C++ or Delphi. The hardware-dependent and time-critical code needs to be transferred to a DLL, which is then loaded directly into the real-time context. This way the .NET environment is also supported, so that even C# can be used as programming language for the main parts of the application.

32-bit as well as 64-bit applications can be generated from a single uniform code base. Both versions are completely source code compatible—with a special module (KiK64) even binary compatible.

The software provides immediate accessibility with program frameworks for programming languages as well as compilers listed below. Download the free trial version now!

Further information …


CAN Module

  • Real-time communication over CAN (Controller Area Network)
  • Supports cards from Peak, Star Cooperation (Eberspächer), EMS Dr. Wünsche, ESD, Ixxat and Kvaser (hardware support on request)
  • Support for CAN FD (Flexible Data Rate)

Further information …


CANopen Module

  • CANopen® Master in real-time, automatic identification of CANopen topology
  • Process data and service data communication (PDO + SDO) as well as mailbox communication

Software combination

Kithara RealTime CANopen comes with the following features:

  • The software can be combined freely from all available modules, few dependencies exist
  • The name of development and runtime filescan can be chosen freely
  • Simplified installation (no registry entry)
  • Regarding new versions, no modification is necessary
  • With the purchase of the module you will automatically receive a developer's license
  • Favourable price scale conditions for runtime licenses
  • Always state of the art software due to quarterly updates via download
  • Expandable at any time with additional modules


Real-time capability can only be achieved on the kernel level. For this purpose a programming language is required that is able to generate native x86 or x64 machine code, e. g. C/C++ or Delphi. Nevertheless the Instantly usable program frameworks for the platforms mentioned above are part of every software delivery. Kithara RealTime Suite supports various platforms, for example a .NET environment.

System Requirements

The products of Kithara RealTime Suite support a wide range of hardware and software combinations

If you have questions regarding the system support, please contact us!

Operating system

The software supports the following operating systems:

  • Windows 7, 8 and 10, each 32 and 64 bit, dedicated mode
  • Windows Server 2012, 2015, 2017, dedicated mode
  • Windows Server 2008 R2, 64 bit, dedicated mode


The software runs on the following hardware:

  • CPU: AMD (Athlon) or Intel (Pentium 2), 32 or 64 bit
  • Dual- or multi-core; optional hyper-threading with multi-core, currently up to 48 logical CPUs, higher on request
  • ACPI recommended (Advanced Control and Power Interface), APIC recommended (Advanced Programmable Interrupt Controller). Some features require ACPI-APIC
  • the PC must be able to support PAE (Page Address Extension)
  • Using Gigabit-Ethernet up to 40 Gbit/s, controller of Intel and RealTek are generally supported


Immediately usable program frameworks for the following programming languages / compilers are included in the supplied software (other programming languages can be supported on request):

  • Visual Studio 20xx C++ with MFC user interface (supplied project files: VS 2010/12/13/15/17)
  • C++ Builder (Embarcadero, formerly Borland) VCL user interface
  • Delphi (Embarcadero, formerly Borland) VCL user interface
  • Visual Studio 20xx C# with WPF user interface (incl. C++ DLL for real-time execution, supplied project files: VS 2010/12/13/15/17)

In order to execute code in a real-time context, generally any compiler that can generate a DLL with native machine code, is usable. Furthermore, the Windows application can also be generated with other programming languages, such as C#.
