CATS_NT is a software system for computer aided operation of testbeds with emphasis on the automotive and supplier industries. CATSNT executes on standard personal computers with Windows operating systems together with the proven Siemens industrial tehnology.

CATS_NT – automation system for testbeds in the automotive sector

CATSNT offers the following functions for testing on engine, gear, vehicle and component testbeds:

• Measured values
  - Acquiring
  - Visualizing
  - Calculating
  - Storing
• Testbed
  - Testbed monitoring
  - Fully automatic test cycles

The collected data is analyzed with the help of the system's powerful reporting and graphic functionality. Several CATSNT systems can be linked together via an Ethernet LAN and connected to a higher-level in-house network.

CATSNT is the logical successor to the CATS test system which has served the market superlatively for many years. CATSNT is suitable for serial and development testbeds as well; multifaceted test tasks can be implemented on a user specific basis.

With a cycle rate of up to 100 Hz CATSNT is implemented for measuring, open-loop control, monitoring, closed-loop control, visualization and recording – with a standard PC without the need for additional hardware.

The modular construction of CATSNT allows it to be optimized for each test situation and, of course, expanded for new tasks in the future.

Operation is designed in accordance with the technological tasks and does not require any IT knowledge so that a short course will equip an operator with all the necassary skills to independently set parameters and operate the system.

CATSNT executes under Windows NT/ 2000/ XP and utilizes the complete functional scope of the operating systems, e.g. for networking or for data exchange with other Windows applications.

To strictly adhere to the processing cycle independent of the Windows timing, a realtime extension (RTX) from Ardence (previously VenturCom) has been integrated.

In most cases, CATS is applied with a subordinate testbed control which handles the coordination, safety and control functions at testbed level, meaning that the manual control level is also available independent of the PC. With simple applications, CATSNT can also handle this task.

The CATSNT system generates the following cost benefits:

• Automated processes mean faster and better quality testing
• Automated tests permit a reduction in personnel levels
• Results can be automatically documented for Development or QA (Quality Assurance)
• Reproducible tests allow development changes to be efficiently documented
• The test object and testbed process peripherals are monitored by standard SIMATIC S7 hardware components – your guarantee of an almost trouble-free lifetime and a service concept offering excellent value for money
• The use of standard PCs means you can upgrade to new, more powerful models at any time without hurting your investment
• Suitable for round-the-clock duty
