Yes, if the aim is to continue using proven functionality and enable cost-effective adaptation to new requirements. Yes, if each software is used to do what it does best – DIAdem for visualisation, data analysis and reporting, LabVIEW for creating a wide variety of hardware interfaces, and TwinCAT for PC-based real-time control. Yes, if easy-to-use, […]
There is powerful visualization software available for every PLC that can display current system states in almost any way. And yet there is sometimes the need for a simple way to record, visualize, save and analyze PLC data. If the PLC has a fieldbus interface (e.g. Profinet, EtherCAT, SERCOS III or Ethernet/IP), this is very […]
Or rather: what is the data meant to tell us? The desired information and the required conclusion determine which data needs to be collected and to what extent. For a simple product, it may be sufficient to produce a straightforward ‘pass/fail’ result. And to assess the associated production process, it is then sufficient to analyse […]
Key criteria for selecting a data analysis tool include its ability to access and correlate metadata, its capacity to process large volumes of data, the algorithms available, and the user’s familiarity with the chosen tool. After all, even the most powerful tool is of no use if the user does not know how to utilise […]
Whether it’s a database or individual files, a local drive, a server or the cloud – when it comes to where you store your data, the most important thing is that it is secure – protected against data loss and unauthorised access – and accessible at all times. More important than the choice of storage […]
In principle, information can be extracted from any type of data. However, the content, structure and descriptive information (metadata) play a key role in determining the effort required to do so. Here at müller+krahmer, we therefore regard it as a key advantage that we offer both test automation AND automated data analysis. Because we understand […]
Measurement systems, test benches and data analysis solutions, no matter how complex their design, have only one purpose: to obtain and document information about the device under test, with regard to its functionality and quality. All the effort spent on testing technical systems always leads to a test result which – regardless of how it […]
For a long time, it was everywhere, but recently there wasn’t much to hear about – NI’s big analogue data (TM), characterised by the five Vs: volume, variety, velocity, value and visibility. Of course, it is still there and growing. Perhaps it has fallen out of the spotlight because we have become accustomed to it. […]
The use case is typical: many sources provide data that is evaluated in a standardized way and then used by a group of users. In this specific case, measurements on vehicles in drive simulations produce large amounts of data around the clock. This data is processed, searched for events and used to calculate characteristic parameters. […]
Process data objects (PDOs) are typically used in EtherCAT (and other fieldbuses) to transport (cyclical) real-time data, while service data objects (SDOs) are used for (acyclical) parameterization. But what if the PDOs are not available for cyclical control due to customer requirements, but the reaction of the test object to cyclical setpoints is to be […]
