With more and more manufacturers requesting data-acquisition capabilities, choosing how to provide DAQ for machine lines and stand-alone equipment has never been more important.
"By using data acquisition systems and recorders, best-in-class manufacturers have taken the lead to improve the flow of information from these devices that produce large volumes of real-time process data and store the data in a process historian, which becomes the foundation to drive real-time analytics," says Jack Wilkins, director of sales, Canary Labs (www.canarylabs.com). "By using dashboards and real-time trending, they have improved their ability to detect and react to process bottlenecks or quality issues."
While many considerations must be made before deciding on which components or software to employ, features should be weighed fairly. "While there is no one most-important DAQ characteristic for machine builders to consider, two critical concerns are signal integrity and industrial ruggedness," explains John Lehman, engineering manager, Dataforth (www.dataforth.com). "To ensure information in I/O signals is preserved, a high-performance DAQ system will have isolation to the communication line and adjacent channels and will be tested and certified to meet radiated and conducted emission standards."
With regard to system ruggedness, a DAQ system that can maintain accurate performance in high-vibration environments and operate over a wide temperature range is the optimal choice, adds Lehman. "Additionally, field-side overload protection to 120/240 Vac and a high level of ESD immunity ensure fault-free operation and protect down-line equipment," he says.
DXAdvanced R4 is the latest addition to the DAQStation line of data acquisition and display stations. Standard features include 400 MB of internal flash memory, with an optional USB interface for data retrieval using USB memory devices or configuration with a USB keyboard. All models include custom graphics that allow users to design custom display screens. Historical data review includes a calendar display and search tool and enhanced trend history functions.

|MEMORY AND FLASH
Eco-Graph T features compact flash and internal memory with digital memory and an industrial-grade flash card. Data is lockable/sealable with storage cards for a high level of security. Data can be transferred without software with the use of CSV format, which allows for direct opening in ASCII or a spreadsheet. The free ReadWin 2000 software offers the option of protected data transfers (manipulation-free).
|X MARKS THE DAQ
X Series multifunction DAQ devices for PCI Express and PXI Express are designed to provide enhancements to analog I/O, digital I/O, onboard counters and multidevice synchronization. The devices, which include up to 32 analog inputs (AI), four analog outputs (AO), 48 digital I/O lines and four counters, range from 250 kS/s multiplexed AI to 2 MS/s simultaneous sampling AI. Simultaneous X Series devices integrate up to 16 ADCs on a single device at 2 MS/s per channel.
isoLynx SLX718 data logger/data acquisition system is composed of SLX718 units and miniature SensorLex 8B isolated analog signal conditioners. The combinations offer stand-alone or PC-tethered data logging operation, along with the ability to change I/O on a per-channel basis for eight signal conditioner locations. Up to eight 8Bs, selected from 90+ input types, can be installed directly into the SLX718 unit, allowing signal conditioning functions to be mixed and matched to each application.
USB-4702 eight-channel, 12-bit, 10 kS/s multifunction USB DAQ module provides analog I/O, digital I/O and counter functions. It has the advantages of USB-based devices, including portability and easy installation and includes device manager, WaveScan, which is a data logging tool and includes library examples such as Visual C++, Visual Basic, Visual C#, Visual Basic. NET, Borland C++ builder, Delphi and LabView.

ioLogik W5312 Active GPRS RTU integrates a data logger, a GPRS modem and an I/O controller in one device. The push-based active OPC server is designed to conserve data transmission volume when communicating with SCADA systems; front-end data logging and report-by-exception functions also are designed to minimize unnecessary data transmission.
DT9836S is the newest addition to the series of Data Translation's simultaneous USB data acquisition modules. The DT9836S is a completely isolated high-speed USB module, providing simultaneous analog inputs at up to 800 kHz per channel or 4.8 MHz total. Each analog input channel has its own separate A/D converter eliminating phase shift between each channel. The DT9836S includes six true 16-bit analog inputs for measuring multiple channels simultaneously and complete synchronous operation of all subsystems at 36 MHz.
LGR-5320 data loggers with 16-bit resolution, 16 analog and 16 digital inputs and four encoder inputs, perform high-speed measurements to 200 kS/s directly to a secure digital (SD) memory card. Using analog and digital triggering options, users can collect data to monitor systems and events without dedicating a PC. The loggers ship with DAQLog software to configure the devices and retrieve data via the USB interface or SD memory card.
microNCS provides distributed data acquisition, Modbus RTU (RS-485) master capabilities and, with expansion I/O, control. The system also has a data logger with a backup battery that can archive 64,000 time-and-date-stamped values. The device can be set up using the Internet Explorer Web browser and is part of the NCS Net Concentrator System family.

InfoLink LogBook software tracks, organizes and stores comprehensive process status and event data. It captures operational intelligence via an interface that allows operators to record operator comments and observations throughout the course of a shift. Each entry is documented by date and time, and consistent entries also may be organized by user-defined categories. After a shift is complete, incoming operators can access key historical process data that is then stored within the InfoLink LogBook.
|DATA ACQUISITION SYSTEM
ADRE SXP data acquisition system consists of the 408 Dynamic Signal Processing instrument (DSPi) and ADRE Sxp software for portable asset management programs where speed and flexibility in data collection are needed.
