PLC Market Comeback?

• PharmaTechnology
• Water & Wastewater Systems

PLC Market Comeback? A report from IMS Research says the global market for programmable logic controllers (PLCs) is showing signs of recovery — though only slight ones. The firm forecasts the worldwide PLC market for 2010 at $6.6 billion, compared with $6.3 billion for 2009. With global economies still in flux, the firm's analysts cannot rule out a double-dip recession. IMS estimates that the market won't return to 2008 levels until 2012. The company notes that different industries in different parts of the world have significant impacts on growth in the PLC market, and this article details some of those regional influences.

Wireless LAN Test Suite

Wireless LAN Test Suite The latest version of this wireless local area network (WLAN) test suite includes software for IEEE-802.11n — the latest wireless LAN standard, which received final approval by the IEEE last fall. The suite adds phase-coherent multiple-input, multiple-output (MIMO) RF measurements required for IEEE 802.11n WLAN testing. Other capabilities include error vector magnitude (EVM) and spectrum mask measurements.

Acquire Locally, Access Remotely

Acquire Locally, Access Remotely This data acquisition and analysis software is designed to function — along with the manufacturer's transient recorders and data acquisition hardware — as a complete client-server-based acquisition solution. It also permits operating the equipment over Gigabit Ethernet LANs from any Internet-accessible location in the world. Mathematical functions such as arithmetic smoothing and filtering can be applied to captured traces.

Full-featured USB-based Acquisition

Full-featured USB-based Acquisition The maker of this USB-based data acquisition system says that manufacturers of USB-based gear tend to focus on low cost and ease of interfacing — at the expense of signal conditioning. This product takes the opposite approach, with an eight-slot equipment chassis that accepts plug-in signal conditioning modules. Each module can be selected to meet whatever job you have in mind.

DMM Tricks That Aren't Stupid

DMM Tricks That Aren't Stupid The digital multimeter (DMM) is one form of acquisition module. This article not only outlines the DMM's history, but shows how its functions can be expanded beyond the basics of current, voltage, and resistance, to measuring diodes, LEDs and other semiconductors. More recent and advanced models can add leakage tests, measure termination networks, and make "guarded" resistance measurements.

DACs in Action

DACs in Action Digital-to-analog converters (DACs) play a key role in a wide array of applications, from audio and video products, to distributing programmable voltages on a factory floor, to software-defined radio. This article reviews three DAC applications — in audio products (consumer CD player), calibration, and motor control — and spotlights the role played by the DAC in the overall circuit of each one.

New Approach to DAC Power Efficiency

New Approach to DAC Power Efficiency Designed to address the need for additional channel density in factory automation — while holding down power consumption and thermal dissipation — this quad, 16-bit DAC takes the unusual approach of using dynamic power control. It senses the load impedance and delivers the required power to the load while minimizing power loss in the overall circuit.

Signal Conditioning: A Basic Tutorial

Signal Conditioning: A Basic Tutorial Before acquiring a signal, you almost always have to 'condition' it. This archived tutorial introduces the concept of signal conditioning and why it's needed. It also gives some basic examples of real-world sensors, and the role the signal conditioning circuit plays in matching the sensor to acquisition equipment. One such example is a strain gauge transducer connected in a bridge configuration.

Get a Charge Out of This

Get a Charge Out of This Charge-output piezoelectric (IEPE-type) sensors, with their high-impedance outputs, can be susceptible to noise pickup. This ultra-low noise remote charge converter (RCC) transforms the high-impedance signal from the sensor into a low-impedance output that's less susceptible to noise — holding broadband noise to 5 µVrms. Designed for rugged factory applications, it withstands shock loads to 100g (peak), and radiation to 1.0 Mrads.

The State of Training in Automation (Video)

The State of Training in Automation (Video) Control magazine surveyed its audience about training and skill levels. This video report reveals some disturbing findings: When asked how they get their skills training, the largest portion — 36% — said "I try to read up on it." Given that 70% of respondents said they were older than 40, the fact that training is such a low priority is a significant concern.

Healthcare Goes Wireless (Video)

Healthcare Goes Wireless (Video) Take a look at one hospital's experiment in remote health care monitoring, and how they're mostly accomplishing it with commercial, off-the-shelf (COTS) wireless technology — plus some extra "secret sauce." According to this video report, results are encouraging enough that all parties are beginning to take a look at a whole range of health monitoring possibilities. Watch that pulse rate!
