Ethernet Data Acquisition

Ethernet Data Acquisition Systems (EDAS) provide you with real-time, interactive I/O, allowing you to visualize your plant operations, environment, and productivity. Utilize the open systems environment of Ethernet to integrate your acquired data with your company or enterprise network. Ethernet data acquisition devices plug into an Ethernet network and can then be configured from anywhere on that same network. Often, the devices can be monitored and sometimes controlled via a Web browser.

EDAS CE provides from 8 to 192 points of analog, digital, and serial I/O. The modules provide connectivity to virtually all sensors including temperature, pressure, flow, voltage, current, contact closures, and RS-232 devices. EDAS also supports DOS and Windows 3.1, but these modes of operation were not tried. EDAS units communicate over any Ethernet or Internet network using built-in industry-standard TCP/IP protocol, providing a non-proprietary interface to virtually any host.

Advantech’s ADAM-6000 series analog Ethernet Data Acquisition modules use microprocessor-controlled, high resolution, 16-bit, sigma-delta A/D converters to acquire sensor signals such as voltage, current, thermocouple or RTD. The ADAM-6000 mixed I/O modular design optimizes the performance and usage of I/O and minimizes the engineering efforts and maintenance cost. Advantech’s SFP transceivers ensure your networks operate with maximum performance, reliability, and flexbility.

Wireless technology extends NI data acquisition hardware and software technology to new distributed and portable measurement applications where wiring is difficult or cost-prohibitive. The flexibility of LabVIEW graphical programming and the ubiquity of Wi-Fi network infrastructure make it easy to incorporate wireless sensor measurements into new or existing PC-based measurement or control systems.

Instruments with the stand-alone data logger option feature a built-in multimedia socket that accepts secure digital cards (SD) to which acquired data may be stored without a connected PC. SD memories are the same commonly available mass storage devices used with digital cameras and MP3 players. Instruments without this option must remain tethered to a PC’s USB or Ethernet port during data acquisition and use the PC’s own program and memory to store acquired data. Software selectable gain ranges of 1, 2, 4, and 8 are supported.

Analogue input resolution is user adjustable; 12-bits at max speed of 50kHz increasing up to 16-bits at slower speeds. The user can also select the 24-bit ADC for extremely high resolution, stable measurements at up to 200Hz. Analog input resolution is 12-bits at max speed (10 us conversion time), increasing up to 16-bits at slower speeds (10 ms conversion time).

XML is also a key component of Microsoft’s .NET technology and raw data from our devices can be used directly by applications developed with this technology. We have created examples of importing acquired data into Excel, Access and .NET. XML (Extensible Markup Language) is the language of the Internet and by using XML we bring two key benefits: 1) XML is an open standard. You will not be trapped with a proprietary protocol.
