The Loggito LAN Data Logger by Delphin proves that good things do indeed come in small packages! The Loggito is excellent for distributed monitoring systems, data acquisition with a low number of channels and other low power applications in a wide variety of industries. The Loggito can be used as a central data processing/data storage unit or it can be equipped with a card to provide 4 or 8 universal analog inputs for mV, mA, thermocouples or RTD’s (-R model cards). Additional digital I/O cards are also available to provide up to 8 digital inputs/outputs.

The Loggito LAN Logger module can be used connected to a PC or equipped with internal data storage to create a stand-alone system for data acquisition or data logging. It can be used with conventional software channels, which means that it can internally pre-process and calculate measurement channels. The module can also act as the coordinator for your measurement network and is the interface to the ProfiSignal data acquisition software and ProfiSignal Web browser based monitoring software.

ProfiSignal Go enables users to portray measurement data online and offline and to carry out detailed analysis. The software can portray the Expert Logger‘s measurement data in trends. Users can choose between y(t) or y(x) diagrams as well as a range of other analysis diagrams. ProfiSignal Go is especially intuitive to make it highly user friendly.

Installation is very simple. It takes just a few mouse clicks to go from sensor connection to trend output.

Unlimited Trends

There are virtually no limits to trend portrayal for online and offline measurement data. Archived and online measurement data can be evaluated without having to interrupt ongoing measuring procedures. This is a unique function that is especially valued by customers.

In addition to y (t) diagrams are y (x) – and logic diagrams. The ProfiSignal Go Toolbox contains trend functions such as movable axes, zoom functions, cursors, markers and data export (e.g. as CSV or EMF files). Using the toolbox is self-explanatory. Configured trends can be saved and reused.

For visualization and automation functions, software upgrades to ProfiSignal Basic and ProfiSignal Klicks are possible at any time.

Alarm Functions

ProfiSignal Go also provides alarm management. A global alarm list provides a clear portrayal alarm notifications in tabular form. Alarm settings for the monitoring of over-runs, under-runs, process violations, status outcomes etc. are configured using the DataService/Configurator software. Measurement data can also be used to trigger specific actions, e.g. sending text messages or emails or switching digital outputs.

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
