Data Acquisition Control.

The testing of high energy chemical lasers requires high data acquisition rates and stringent timing accuracy in control of the laser under test. Commercially available digital hardware, straightforward design techniques, and extensive application software were used to successfully implement a complex laser test system. The present paper discusses requirements, data acquisition and recording, the test control and sequencing, and the test control language for the laser test system. A system block diagram is presented along with system specifications and parameter displays.

NetAcquire products are advanced network-based data acquisition and control devices. Each NetAcquire system acts as a gateway between the analog, digital, and serial "real world" and the network world.

Programming section for information). Telephone or radio modems may be used with the ADR interfaces to permit remote Supervisory Control And Data Acquisition (SCADA). Thousands of systems are in use by educators, integrators, OEM's, and invarious industries. Custom solutions are offered at very reasonable rates and quick turn around time.

Like the PCI products mentioned above, UEI also offers a DAQ product line for the CompactPCI/PXI platform. The PXI platform (based on CompactPCI) allows for data acquisition systems deployment in industrial environments where more rugged, and robust rack-mounted systems are required.

The HP 3497A Data Acquisition / Control Unit combines the capabilities of several instruments and is a basic building block of an automatic data acquisition and control system. The HP 3497A will be used in an HP-IB automated system and can be viewed as a precision measurement and control computer peripheral.

A picture says more than a thousand words. Review historical data while acquiring and displaying current data. The alternate zoom feature gives you two zoom areas simultaneously within the same waveform. And with the triggered display modes you have a stable, flicker-free look at the data.

Data Communications need protection. Data communications system lines run long distances and are exposed to hazards. Data communications systems must function among electrical transients and noise, ground loops, and lightning strike.

Engineering services including computer aided manufacturing, customer test equipment, data acquisition & control, & lean manufacturing that serve nuclear sector. Industries served include automotive, medical, consumer goods, bio-tech, agricultural and nuclear, electronic, & chemical industries.

There is, in several industries, considerable confusion over the differences between SCADA systems and Distributed control systems (DCS). Generally speaking, a SCADA system usually refers to a system that coordinates, but does not control processes in real time. The discussion on real-time control is muddied somewhat by newer telecommunications technology, enabling reliable, low latency, high speed communications over wide areas. Most differences between SCADA and Distributed control system DCS are culturally determined and can usually be ignored. As communication infrastructures with higher capacity become available, the difference between SCADA and DCS will fade.

Designs, develops, manufactures and markets complex electronic instruments and systems for high-volume production and assembly testing. Product offerings include integrated systems solutions, digital multimeters and data acquisition / switching systems, data acquition modules / cards, instruments and personal computer (PC) plug-in boards that can be used as system components or stand-alone solutions.

The term SCADA usually refers to centralized systems which monitor and control entire sites, or complexes of systems spread out over large areas (anything between an industrial plant and a country). Most control actions are performed automatically by remote terminal units ("RTUs") or by programmable logic controllers ("PLCs"). Host control functions are usually restricted to basic overriding or supervisory level intervention. For example, a PLC may control the flow of cooling water through part of an industrial process, but the SCADA system may allow operators to change the set points for the flow, and enable alarm conditions, such as loss of flow and high temperature, to be displayed and recorded. The feedback control loop passes through the RTU or PLC, while the SCADA system monitors the overall performance of the loop.

ISO 9001:2000 certified engineering services for acquisition and reporting of statistical process control data. Data acquisition and control includes statistical process control data collection, inspecting parts and preparing report. Standard and customized report formats available.

Data acquisition begins at the RTU or PLC level and includes meter readings and equipment status reports that are communicated to SCADA as required. Data is then compiled and formatted in such a way that a control room operator using the HMI can make supervisory decisions to adjust or override normal RTU (PLC) controls. Data may also be fed to a Historian, often built on a commodity Database Management System, to allow trending and other analytical auditing.

Electronic engineering services for data acquisition and controls. Engineering capabilities include electrical circuit, radio frequency and infrared designing, interfacing, timing analysis, electrical component processing and field-programmable gate array (FPGA) development.

and 3,735,350, both to Lemelson, teach a scanning system which provides a solution to the alignment or skew problem. A guide is provided for directing a scanning element across a row of characters. Thus, prior to scanning, the characters are aligned with the guide. Then, it becomes fairly simple to maintain alignment of the scanning head with the row of characters by sliding the head along the guide. However, even in these patents, codes and not characters are being scanned. A problem may be that although skew errors have been removed, it is still necessary to recognize the scanned characters. If the speed of scanning varies or even is different from a pre-established ideal speed, the proportions of characters that have been read and converted into electrical signals will vary, thus rendering the problem of recognition extremely difficult.

Data acquisition and control engineering services; also, mechanical, pneumatics, hydraulics and robotics automation systems; specializing in turn key automation, robotics, control system integration, computer programming and testing. Panel fabrication also available.

The Perception Remote Control option provides a variety of commands that allow you to setup an instrument, control an acquisition, fetch "live" data for display, and export data for storage. With a SOAP interface you can link Perception into your test environment on different platforms like Windows, Linux, or Unix.

Engineering and designing services for automation, data acquisition and control systems. Engineering services are available for harnesses, assemblies, automation systems and power control systems. Capabilities include mechanical, electrical, software, graphical and SCADA system designing and integration.

The HMI package for the SCADA system typically includes a drawing program that the operators or system maintenance personnel use to change the way these points are represented in the interface. These representations can be as simple as an on-screen traffic light, which represents the state of an actual traffic light in the field, or as complex as a multi-projector display representing the position of all of the elevators in a skyscraper or all of the trains on a railway.
