Delphin Technology AG

- Version Go - Data Acquisition and Analysis Software


Delphin's ProfiSignal Go software is intended for users in industry, universities and institutes who are involved in measurement and process data acquisition and evaluation. ProfiSignal Go can be run with any Delphin hardware products. Customers enjoy the user-friendliness of Delphin products. Delphin has discovered the fastest path to get from sensor to trend output. Users are able to quickly commence measurement data acquisition and evaluation. A range of functions are available to users to meet their measurement requirements.

  • Multichannel measurement data acquisition and evaluation
  • Users can monitor and evaluate processes both online and offline
  • Measurement data can be exported to other analysis programs (e. g. Excel, Diadem)
  • Supports continuous processes with continuous data recording
  • Supports batch processing with preset start/stops
  • Network compatible
  • Parallel running of multiple diagrams with different configurations and channels

Hardware and software from a single source

Delphin offers following hardware products:

Online analysis
ProfiSignal Go is based on online analyses, each with a diagram and channels selected by the user. The online analysis feature is the shortest method available for users to get from sensor to trend output, and the simplest method available for users to analyse measurement data. Potential applications include servicing, mobile applications, error detection and system installation. Online analyses can use trend diagrams (y(t)-diagram), characteristic curves (y(x)-diagram) or logic diagrams.

Y(t)-diagrams and trends
A trend can process large numbers of channels. A hide/show function enables the display and highlighting of specific channels. A trend can have up to 4 measurement axes. Each axis can be assigned channels. Axes can be extended and compressed and cascaded.

Recording data from online analysis
Batch data recording
Batch recording enables users to use dialogs to define process start/stops. Manual and automatic start/stops are available. Data files are automatically assigned names but users can also manually enter data file names. The saving of batch data is useful for series testing/experiments, fault diagnostics and the monitoring of machinery and production processes.

Continuous data recording
Data from continuous processes can be monitored online and evaluated offline. Continuous data storage is useful for monitoring continuous production processes, for acquiring data, for long-term trials/experiments etc. Measurement data can be saved in the background while users set up new online analyses and evaluate data from other online analyses.

Measurement data analysis
ProfiSignal Go is equipped with online and offline modes. The online mode enables users to monitor the state of their current processes.
In offline mode, users can access historical data even at high data resolution. Panning is possible along the time axis. Specific data can be visualized by compressing/extending the time and value axes.
Users can switch between online and offline modes at the click of the mouse. ProfiSignal Go has an extensive range of analysis functions. These are accessed via buttons on the toolbar.

Test channels are channels that require no hardware. They enable users to assign channels to diagrams with sine, square and sawtooth functions. Users are therefore able to set up and experiment with the online analysis feature. The test channels can later be replaced with actual channels using drag and drop.

ProfiSignal Go in networks
Delphin's measurement hardware can be integrated into existing data networks via LAN-interfaces. Channels can be fed from any number of Message and Expert devices. Users can install ProfiSignal Go on any number of PCs within their company's network. Data can then be evaluated from any authorized PC.
Users can also directly connect Message devices to a PC without having to use a network.

Interfaces and drivers
Delphin products are equipped with drivers and interfaces to enable the import/export of data to external hardware and software. Laboratory equipment (e. g. scales, analysis/output devices) can be connected via USB and RS232/RS485 interfaces. A variety of protocols are available.
PROFIBUS and Modbus are used for data transfer between process control systems. The following interfaces are available for third-party software:

  • LabVIEW™
  • DASYLab™
  • OPC-Server
  • OPC Client
  • Modbus TCP-driver
  • OCX-driver
  • GPS-converter


Switching between online and offline evaluation is at best difficult and sometimes not even possible.

Delphin's system of storage eliminates any restrictions on online or offline evaluation. The ProfiSignal Go software offers continuous long-term data storage combined with batch storage capabilities.

The intelligent recording of averages and minimum and maximum values enables the high-speed portrayal of current and archived data from µs to annual averaging levels, at high-resolution and including peak values.

Large data volumes can then be clearly portrayed at high speed.

ProfiSignal Go allows clicking on the time axis to select the required time range. A scroll function is available when the exact time range is unknown.

A powerful recorder function is available for recording batch processes. This stores data to Delphin databases or individual data files either manually, at predefined intervals or via triggers (events, channel, time etc.).


Use drag & drop to select the required channels and immediately portray online time signals in the diagram format required.

Any signal from the Message and Expert series can then be directly portrayed on up to four y-axes.

There is also the option to display digital signals within logic diagrams. The trend is then split with a window available for digital signals. This allows analog and digital signals to be analyzed simultaneously.

Functions also include cursor and statistical features as well as marker and CSV export for additional analysis, e. g. in Microsoft Excel or National Instruments Diadem.

ProfiSignal Go has adapted the zoom feature from the Adobe Reader to enable fast orientation when using trends.

Calculation channels
An integrated formulae manager enables measurement data from Expert or Message series to be computed online and offline, and for the results to be stored as well as portrayed in diagrams. Complex efficiency formulae as well as basic temperature or pressures averaging are simple to implement.
Data storage that eliminates the divide between online and offline analysis
Intelligent data storage enables direct access to extended time ranges even for archived data. Users need only to click on the time axis and select the required time range.

ASCII export at just a few clicks
Use cursors to select a time range within a diagram and then export the data to a data file for processing by ProfiSignal, or as a CSV file for further processing with, for example, Microsoft Excel or National Instruments Diadem.

To export the entire data requires just two mouse clicks to store the data as an ASCII file to a hard disk.
