Ethernet data acquisition system

Usually the DS-NET system is connected to a host computer running DEWESoft™ online data acquisition software. Up to 160 kS/s can be received from a single DS-NET system and then be processed, visualized and stored on the host computer.

But DS-NET also offers real-time performance!

DS-NET runs its own internal real-time operating system and can handle output and alarm functions directly inside the instrument. Thus defined response times are guaranteed - completely independent of any PC.

Stand alone data logging

Every DS-NET system is ready to be used as a rugged stand-alone data logger - without any additional costs! The logging process is configured by a single click in DEWESoft™ software. Measurement data and calculated values can be stored to a USB memory-stick; up to a limit of 32 GB. For triggered storing an aggregate sampling rate of max. 160 kS/s and up to 2 million samples per trigger event are the limit. For continuous storing an aggregate sampling rate of max. 20 kS/s is the limit. Data is stored into files of max. 2 million samples each without any gap between the files. USB sticks can be hot-swapped during measurement without loosing any data thanks to the internal buffer memory. Data analysis can be done offline in DEWESoft™ software.

Redundancy in data acquisition

The combination of the data logging feature and DEWESoft™ online recording software gives you redundancy in data acquisition for maximum reliability. Both, a USB stick and a measurement PC (via Ethernet), are connected to the DS-NET system in parallel. Data is logged to the USB stick while you are using DEWESoft™ to process, analyze and store the very same data at the same time!

As a result, even if your Ethernet connection should break during a measurement, your data is safe, since it is logged to the USB stick.

Industrial monitoring – Data cloud

Multiple DS-NET systems are connected to an Ethernet LAN so that the measurement data can be processed, analyzed and stored by any computers within the network. For highest data quality all the measurement nodes are synchronized to each other either by hardware for best performance (time skew typ. 1 µs) or software (time skew typ. 1 ms).
Usually LabVIEW™ software applications are created for each particular installation.
Clients also can read the online values via Modbus TCP/IP and of course data can be stored to your SQL database, even to a remote server over the Internet!
Of course DEWESoft™ software can be used, too.

Complete instrument running local DEWESoft™ software

A compact CPU module available which adds a full-featured PC to your DS-NET system and turns it into a complete instrument. The CPU module enables you to run DEWESoft™ software locally. Measurement data is stored directly onto the internal flash disk and the local PC can be remote accessed via WLAN!
