Delphin launches the ProfiSignal measurement and automation software in Release 4.0. In addition to various further developments, the new features include the integration of a web server into the software's DataService. This web server enables worldwide access to the measurement data via the Trend app or web application. An API and an XML interface are available for integrating the measurement data into web pages and your own applications. With the Trend app included in the software package, users can track their measured values live on a mobile device. It also provides access to historical data. The measured values are displayed in a y(t) diagram; the user can use swipe gestures to zoom into historical data and display any offline time ranges. The integration of the 'Diadem' driver enables the measurement data to be exported to this mathematical analysis program. The measured values can be exported as ASCII or binary data with just a few mouse clicks. In order to archive measurement data in a traceable and tamper-proof manner, the functional requirements of FDA 21CFR Part 11 have been completed in the current release.
