Scope of testing and functions

Flexible & integrable

MCD Comet combines TestStand®integration, customizable user interfaces, open extensibility, and hardware and communication connectivity in a central test environment. Functions and components can be merged according to the respective test requirements.

User interfaces can be individually designed and existing TestStand® functions can be integrated directly into the application.

  • Predefined user interfaces
  • Individual operating concepts with graphic elements
  • Integration of existing TestStand® functions
  • Adaptation to the respective testing process

The open software architecture enables the integration of additional software components and functions without having to re-set up existing test processes.

  • External DLLs
  • Third party software
  • MCD tool monitors
  • Visualization of test processes

Measuring devices, PLC systems and other hardware can be efficiently connected and controlled via various communication interfaces.

  • TCP/IP and UDP
  • RS232
  • CAN and LIN
  • Measuring devices and PLC systems

Additional testing, analysis and automation tasks can be integrated within the central test environment.

  • Image processing
  • Audio and video signal analysis
  • Boundary scan tests
  • Control of robot arms

A look inside the MCD test solution

Variant-specific test logic

The test bench checks all functions present in the exterior mirror:

Camera systems inspect lighting functions and mirror positions, while actuators, folding mechanisms and electrical functions are tested automatically.

Adjustment and folding functions

Mirror heating

Electrochromic dimming glass

A camera system captures lighting functions, symbols and mirror position.

Turn signal

Lane change assist

Surround lighting

Different equipment features are detected automatically and tested accordingly.

Camera function

Country-specific variants

What’s missing matters, too.

Negative testing ensures that equipment features which are not installed cannot be activated. It also verifies that missing features remain unavailable.

FREQUENTLY ASKED QUESTIONS

FAQS

MCD Comet is part of the MCD TestSuite and is used for the development and execution of individual test and inspection applications. The software has been specially developed for connection to NI TestStand® and thus connects MCD hardware and software to the NI sequencer. In this way, existing customer processes can continue to be used in combination with the MCD software.
MCD Comet supports TCP/IP, UDP, RS232, can and LIN, among others. In addition, PLC systems, external hardware, SQL databases and other software components can be integrated.
Yes. The software is open and can be extended via C#scripts, external DLLs and third-party software. MCD tool monitors can also be seamlessly integrated.
MCD Comet supports, among other things, the storage of measurement data in SQL databases, automated process monitoring, image processing, audio and video signal analysis, boundary scan tests as well as the control of PLC systems and robot arms.
MCD Comet already provides numerous functions as standard, from TestStand®integration to individual user interfaces to hardware connection and process monitoring. As a result, development effort, project times and maintenance effort can be reduced.
