Software for test and measurement technology.

Different types of software are used in test and measurement technology depending on the requirements and area of application. These are the most important software applications:

• Data acquisition software (DAQ software): This is used to record, process and store measurement data from various sensors and devices.
• Measurement data management software: This is used to collect, analyze, visualize and log measurement data. Typical functions include statistical evaluations and data filtering.
• Calibration and testing software: This is used to calibrate measuring devices and for automated test sequences. Typical applications include checking accuracy and creating test reports.
• Simulation tools: These help with the simulation and modeling of physical systems, processes and procedures, and are used, for example, in the development of new test methods and the optimization of measurement setups.
• Automation software: This is used to automate and scale test and measurement processes; typical functions include test sequence control and the integration of multiple devices in one test platform.
• Programming software: This is used for the development and scaling of test and measurement sequences.
• Device-specific software: This is mandatory for operating and controlling specific measuring devices or test benches. It is typically used for configuration, real-time monitoring and remote device control.
• Quality management software: This documents and manages test and calibration processes in accordance with quality standards, including ISO 9001 and IATF 16949.
• Cloud-based analyses and monitoring software: These are used for storing and analyzing measurement data in the cloud, and they enable remote monitoring. The advantages are their scalability and location-dependent access.

Generally speaking, good data management software allows you to analyze and display a large amount of data in different formats at the touch of a button, so that users can quickly obtain useful test results. The quality of measurement data management software is reflected on the one hand in its intuitive operability. Other aspects include:

• The software can seamlessly import and process common data formats from various data sources.
• The software offers a comprehensive selection of different chart types for the appealing and target-oriented presentation of data and measurement results.
• Intelligent functions allow calculations and displays to be automated without the need for programming, so that analyses can be easily transferred to other measurements.

Good automation software is flexible, intuitive and future-proof in state-of-the-art inspection and test environments. It enables the seamless integration of different measuring devices, sensors and test benches, regardless of the manufacturer. Its flexibility is reflected in its modular structure and the ability to support specific processes individually. An intuitive user interface with graphical programming options such as drag-and-drop ensures simple operation and fast implementation without in-depth programming knowledge. Another feature is real-time control, which is particularly important for dynamic tests and in applications with real-time signals. Automated test processes that can carry out test sequences independently and trigger alarms in the event of deviations save time and reduce human error. The software automatically records, saves and documents test results, which facilitates compliance with standards and supports quality assurance. State-of-the-art automation software also enables interoperability with other software solutions, including analysis-, simulation and ERP systems. In the face of increasing requirements and new test standards, it's scalability means that it can be extended, ensuring long-term, future-oriented usability. Users also benefit from cloud-based functions that enable centralized data management and location-independent access. Advanced functions such as artificial intelligence and machine learning open up additional potential, for example through automatic pattern recognition and the optimization of test results.

LabVIEW+ is a bundle of various individual software applications from NI, including TestStand, DIAdem, FlexLogger, InstrumentStudio and LabVIEW. These are professional measurement and analysis tools that can be used to create automated test systems. The improved workflow shortens the development time.
Each software component has special functions to accelerate and standardize various test procedures: TestStand can be used to create test sequences for automated production and validation tests. DIAdem is a data management software program for the evaluation, visualization and documentation of measured values. FlexLogger is a no-code software program for data acquisition and InstrumentStudio makes it possible to work with multiple devices simultaneously; both together simplify device configuration and measurement setup. LabVIEW is a graphical programming environment for the development of automated test systems with a connection to any measuring device. LabVIEW+ is manufacturer-independent, i.e. existing measuring devices can be integrated into a test system.

Engineers can use the LabVIEW+ Suite to analyze large amounts of data, create protocols, and develop automated test sequences for validation and production testing that can be controlled and monitored from anywhere in the world. The bundle is worthwhile for users who want to use at least one other NI software in addition to LabVIEW Professional. For simple measurement data acquisition, individual applications such as FlexLogger or LabVIEW are sufficient.

The LabVIEW+ suite from NI provides seamless integration with various measurement devices, real-time data acquisition, comprehensive visualization and analysis tools, and scalable automation capabilities. Its advantages lie in its flexibility, intuitive operation and the ability to standardize and carry out complex test processes efficiently. This makes it a powerful, integrated solution for test and measurement technology.

Cloud-based solutions offer numerous advantages for test and measurement technology. They enable the centralized storage and management of measurement data and make it accessible at any time and from anywhere. This facilitates collaboration between teams, especially for projects at different locations. Thanks to scalability in the cloud, large volumes of data can be processed and stored efficiently without the need to upgrade local hardware. Cloud platforms also enable the use of modern technologies such as artificial intelligence and machine learning for optimizing data analysis. Security functions such as encrypted data transmission and access controls ensure the protection of sensitive information.

The development of software in the field of test and measurement technology is currently characterized by several trends. The increasing integration of artificial intelligence and machine learning enables a deeper analysis of measurement data and automated optimization of inspection processes. Cloud-based technologies are opening up new possibilities for centralized data storage and location-independent access. In addition, intuitive graphical interfaces and no-code or low-code platforms are making the software increasingly easy to use. Sustainability is also gaining in importance with software solutions that promote energy efficiency and resource management.

The decision between a one-off purchase (perpetual license), a license with a limited term (subscription license) and a permanent license with a maintenance contract depends on a company's individual requirements, planned use and budget. A one-off purchase is particularly suitable for long-term and stable applications that do not require frequent updates or new functions. The advantage is low overall costs over time; disadvantages can be high initial investments and limited update options. A subscription or limited term license features lower entry costs, regular updates and greater flexibility, making it ideal for temporary projects or rapidly changing requirements. However, the running costs may be higher in the long term and access to the software ends as soon as the license is no longer renewed. The permanent license with maintenance contract combines the advantages of both models. It enables long-term use with a one-off purchase cost, while the maintenance contract ensures regular updates and support. This model is particularly suitable for companies that rely on a stable solution but still want to remain flexible in order to integrate technological innovations.
