Not Even Your Older Brother's HMI
It's not really an HMI. It's more of a way to change your idea of what an HMI can be and, at the same time, simplify your ability to meet all those calls for access to data any time and place on whichever device the user prefers. Called groov, it's, for want of a better term, an all-purpose, almost plug-and-play way to build, deploy and view scalable operator interfaces to monitor and control systems and equipment on almost any device, anywhere, from any modern browser.

A Look at the Smart Grid's Demand Side
By now, nearly everyone has heard about the Smart Grid. But few think about it as having two sides - a supply side and a demand side. The supply side is operated by utilities, pushing energy to users. The demand side is populated by those users, and Arun Sinha, director of business development for Opto 22, a supplier of factory automation and control solutions, argues that users already have the power to start building intelligence into their energy management platforms, even as they wait for the utility companies to complete the Smart Grid's supply side. In this conversation with Control Engineering, Sinha explains how users can start using Smart Grid principles to save money on energy costs today.

Energy Management: More Financial Issue Than Tech Issue
As manufacturers look to cut costs in the post-Great Recession business climate, the desire to become more energy efficient has become more prevalent among businesses of all sizes and types. Many find themselves investigating the ways in which they can address energy issues and learning about technology designed to help them achieve their energy goals. What are the relevant questions that they should be asking? Where are they falling short in their energy management strategies? Arun Sinha, Director of Business Development for Opto 22, a manufacturer of energy management and remote monitoring products, recently answered those questions and many more in a conversation with Manufacturing Business Technology.

There's an iPhone or Android control app for that
Another controls maker offering iPhone access is Opto 22, Temecula, Calif. Its iPAC app lets users monitor and control Opto 22 Snap I/O points and PAC control variables, tables, and charts from an iPhone or iPad. The iPhone accesses the network either through Wi-Fi or a cellular link. Security in this case comes from the password protection on the local network. Once connected to the control network, the app automatically discovers the Opto 22 devices and provides information about each one, such as its IP address and the control strategy it is currently running.

Leachate Management System Provides Remote, Ethernet-Based Control System for Landfill Operators
Based in Cheshire, England, System Devices UK Ltd. provides automation systems and support to customers in the United Kingdom and Ireland. The company's expertise covers automation and monitoring systems, supervisory control and data acquisition (SCADA) and robotics. In recent years, the company has provided control systems to landfill operators that not only meet their immediate needs, but are so flexible, they allow for future expansion without having to change hardware or software later in the system's life cycle. According to System Devices' Darren Weissenborn, these leachate management systems use Opto 22 SNAP PAC programmable automation controllers and I/O as the key components that let landfill operator customers connect to, continuously control and acquire data from pumps, valves and other equipment at outstations, ponds, control centers, and all over their individual sites.

Monitoring System Empowers Energy Efficiency Program
Thomson-RCA installed an AutoPilot Energy Information System, comprising Opto 22 hardware and software and designed by Holmes Energy. Using analog and digital interfaces that connected Opto 22 I/O processors to field equipment via multiple I/O modules, the Autopilot System was able to monitor 108 I/O points. The monitored machinery and equipment included gas and electric meters, as well as chillers, cooling towers, boilers and water heating equipment. The AutoPilot System also monitored the facility’s compressed air system. This, in turn, enabled tracking of the electrical demand, power consumption, with system pressure, and airflow associated with two 500-hp Centac compressors and one 350-hp Worthington compressor.

Data Center Energy Efficiency: The OptoEMU Sensor
Data centers are large facilities that include a huge assortment of servers and other computer hardware. Keeping this equipment operating and the facility up and running 24/7 is certainly of the utmost importance. But meeting the power requirements to accomplish this can be incredibly expensive. The OptoEMU Sensor can be implemented in these data centers and, after studying their energy data, data center managers will have the information they need to enact procedural and operational changes that lower utility bills.

Monitor to Reduce Energy Consumption
Tracking power consumption in real time allows companies to control energy usage and avoid peak pricing. "One of the main reasons monthly electric bills provide so little help when attempting to reduce power consumption is because that bill arrives days or weeks after the actual consumption has taken place," says Benjamin Orchard, application engineer for Opto 22. "The lack of real-time monitoring causes the customer to miss many of the opportunities for cost savings."

Apps of Steel
Interest in industrial mobility can be credited to the consequence of trendy devices, lower-cost connectivity, and tech-savvy "Millennials" -- also known as Generation Y -- now entering the workforce. Applications (apps) to foster operations and maintenance efficiency abound for both rugged and consumer-grade wireless technologies, but getting the highest return on your mobility investment requires matching the strategy to your particular environment.

Energy monitoring provides data to optimize air compressor efficiency
When Thomson purchased RCA from General Electric, operations continued at RCA facilities, including those in Indianapolis, Indiana. This plant was quite large, with a central boiler plant providing chilled water, compressed air, heat and domestic hot water to several buildings spread over more than 80 acres. Thomson needed a way to identify and track energy use in the various systems and equipment on this campus. To get the needed data, Thomson-RCA installed an AutoPilot Energy Information System, comprising Opto 22 hardware and software and designed by Holmes Energy.

Cutting-edge Cooler Hits 90% Efficiency with Help from Networked Controls
The AZFlow water distribution system uses an embedded SNAP control system from Opto 22 as its central component. The system gathers sensor data such as surrounding air temperature and humidity, then sends this data to the SNAP processor via analog I/O modules residing on a SNAP rack. The system uses a proprietary algorithm executed by a Linux-based controller to correlate the instantaneous water evaporation and water application rates so the proper volume of water is delivered across the media.

I/O Module Replacement Advice: Plan Ahead on Instrumentation, Space, Design
Proper planning is where everything begins. Too often, I/O upgrade projects are reactionary. Perhaps there are new and specific production problems, or maybe the control system is very old and, due to attrition, there's no one left who understands it; or maybe the person or persons who designed the control programs have left the company, modifications need to made, and now there's no one left who understands how to make the necessary software changes. Smooth I/O upgrades almost always require a huge commitment in terms of proper planning, which should take into account things like interdepartmental collaboration, costs, time, personnel, and of course, wiring.

Inside Process: Instrumentation Challenges of Walnut Processing
Woodside Electronics Corporation http://www.wecotek.com/ provided walnut grower Fedora Farms with burners and control fans for their walnut dryers, along with appropriate sensors and a system controller. The instrumentation included portable moisture meters to work a custom set of radio frequency circuit boards designed by WECO that monitor the dielectric constant of the nuts in order to determine their moisture content. This method involves passing low-frequency radio signals or electrical currents through the walnuts. Correlations are established between the conductivity of the product and the amount of moisture it contains. So when the walnuts' conductivity reaches a predetermined value, they're considered sufficiently dried. Fedora Farms' automation system uses the moisture information to open and close the air door under every bin at just the right time. Fans and burners are shut down as soon as the nuts in the bins are dry. This makes processing faster, increases profit, and also saves energy.

Virtual Power Plant Implements Opto 22 SNAP PAC System for Hydrogen Production
For large enterprises like power plants and water treatment facilities, it is common for myriad disparate control systems to be in operation. In most cases, the control equipment--sourced from different vendors, each with its own area of expertise--is often composed of a programmable logic controller capable of operating a particular piece of equipment, but with little additional functionality. The operator interface to these controllers is typically some form of a local display panel with some or no connectivity to the rest of the enterprise. To address Sotavento's multiple control system issues, Gas Natural contracted systems integrator Optomation Systems to design an integrated supervisory system for the Sotavento site. The system is based on the Opto 22 Snap PAC System platform.

5 Tips to Launch Your Energy Monitoring Project
The premise is simple -- to reduce energy costs, manage energy consumption. However, managing consumption requires that you monitor and understand your energy usage. Here are five tips that will help you get started:
1. Get buy-in from the top.
It's easy to switch to fluorescent light bulbs or raise the temperature on the A/C, but real energy management is going to require support from the top. How do you sell energy monitoring at the highest levels of your organization? Presently, few organizations are set up to account for their energy usage. Power bills typically go straight to personnel in accounts payable, who don't ask questions but simply cut checks. Even if managers look at a power bill, the bill shows no detail on when or where energy was used.

Control System Powers New Marine Vehicles
When he designed a 20-ft prototype unmanned ocean vehicle, Payne Kilbourne used Opto 22 SNAP PAC input/output modules and programmable automation controllers. The system can handle the large quantity and variety of inputs and outputs needed for power and navigation, as well as sensing, monitoring, and gathering data. Thus, the SNAP PAC serves as a central controller that uses both serial and Ethernet communication to connect and regulate a multi-vendor team of micro controllers and marine instrumentation, each with its own area of responsibility, including wing (sail) control, steering, and power management.

What's New in Ethernet
The latest news and trends for Ethernet center around: switches that can handle application in harsh environments, security, wireless, as well as the introduction of new Ethernet compatible versions of standard networks, some of which operate without an Ethernet switch.

Tips on Designing an Energy Monitoring System
Machine designers, integrators, and many others require systems to help them monitor and gather the power consumption data that will ultimately help them slash their energy bills. To assist in this endeavor, Opto 22 offers several design tips.

Energy Management Strategy, Roadmap Needed?
A lot has been written about energy management and how manufacturers can turn fixed energy costs into a variable cost and improve efficiency at plants, factories or commercial buildings. At a recent energy management software conference in Chicago, Arun Sinha, Dir. of Business Development, Opto 22, discussed how to gain insight on the energy management culture and technology trends.

Get Paid to Cut Power Consumption
The ability to measure and model energy consumption has benefits that go beyond allocating energy costs to products and processes. It also allows companies to participate in the demand-response programs being offered by many utilities. In these programs, utilities pay businesses to reduce their energy consumption during times of peak demand.

Energy Saving Opportunities
At Supervalu, the OptoEMU Sensor monitors both pulse-emitting devices (such as utility meters and sub-meters) and the voltage and current of several load panels, chillers, and refrigeration units. Explains AEC's Nathan Bartlett, "We were brought in to design and build a system that provided better sequencing of [SUPERVALU's] refrigeration system and broader, more comprehensive and more powerful demand-response automation in general." To achieve precise levels of control and automation, AEC installed additional Opto 22 components. The company's SNAP PAC System utilizes integrated circuit temperature detector (ICTD) sensors to monitor temperatures, and analog and digital output signals to expertly manage compressors, control solenoids on evaporators and switch relays. Bartlett says that the system can provide interfaces to any piece of industrial-grade equipment. In this case, the system handles about 1,500 inputs and 500 outputs, enabling full demand-response automation of Supervalu's industrial refrigeration, ventilation, and soon, even the HVAC and lighting systems.

Sourcing Tomorrow's Automation Innovations
Says Opto 22 CEO Mark Engman about the next wave of innovation for manufacturing, "It's all about mobility. Everyone in today's developed world has become accustomed to having the ability to communicate, get information and exchange data from wherever they are. This is simply the way people are now working, playing and interacting with others, both personally and professionally. This expectation will soon extend into the world of manufacturing and automation. Automation professionals, for example, will want to access real-time plant data on the go, so they can monitor processes, energy usage and machine

Low Cost PAC Redundancy
"In China, you can't even bid on a project unless you can check the box that you have redundancy," says Benson Hougland, Opto 22 Vice President, Marketing. "It was out of that need that one of the company's newest products was born. The Opto 22 Snap PAC Redundancy Option Kit (Snap-PAC-ROK), unveiled on March 29, can be used to design an Ethernet-based redundant control system with maximum reliability and distributed intelligence that can instantly recover from failure."

Machine Control Integration Produces Savings
Plants are relying on new generations of more fully integrated control technology to run smaller, faster and more efficient machines.

Faster, Cheaper, Smaller Stimulates Better Data Acquisition
The industry appears to be signaling a need for better energy monitoring, observes Arun Sinha, Opto 22's Director of Business Development. What's behind that, he says, is the growing energy awareness in industry and among consumers. But because this awareness crosses into commercial sectors, "we think there's a growing need for a traditional DAQ provider to provide something for energy needs." And because there may be non-automation end-users in commercial businesses, DAQ devices must be "friendly" to those people "who don't know how to program a PLC (programmable logic controller)."

Industrial Embedded Systems
Pay the Toll Machine
PayWerks embedded Opto 22 programmable automation controllers as a key component in its Advanced Toll Payment Machines. These controllers provide the intelligence that enables the ATPM to know the amount of the customer's toll and gives them the ability to pay it. The controller connects to infrared lane sensors that identify the class of vehicle - single-, double-, or multi-axle. The sensors then communicate with the controller, transmitting the data via a standard serial connection to input modules that work with the PAC.

Simplify Signal Processing - Signal Conditioners and Input Modules Cut Control System Costs by Offloading Tasks From Processors
"One of our customers is using our SNAP load cell module in an application that involves weighing grain on a large platform-type scale," says Ben Orchard, application engineer at Opto 22. The customer needed to obtain a more accurate measurement that would compensate for the oscillation and interference caused by workers treading on the scale, and by scale movement and vibration as loads were being brought on and off. "When they configured the load cell module with our PAC Manager configuration software, our customer used the analog filtering functionality to condition the raw load cell signal."

Digital Speed Breathes Life Into Analog I/O
"The little slices between adjacent values are so narrow and fast that today's digital I/O signals are becoming indistinguishable from a true analog I/O signal," explains Tom Edwards, senior technical advisor at Opto 22. "In our case, we have 16-bit resolution A/D converting that divides a 16 mA signal into 64,000 parts, so the original and digital signals look the same. Other developers can use far higher resolution for applications that need more precision."

Is Redundancy Necessary or Superfluous?
"With concerns for improving overall product reliability, PAC and PLC systems used for machine control are often required to feature redundancy," says Surge Yu at Opto 22. He cites companies such as Con-Weigh and Boeing as requiring redundancy in their machine's control systems and notes that often the value of what's being produced might be the impetus for redundancy.

Serious Sustainability: There's a Lot More to Truly Going Green Than Efficiency. Here's How Some Experienced End Users and Their Applications Are Mastering Process Sustainability
Since Jeff Lebesch began making his Fat Tire Amber Ale in 1991, his New Belgium Brewing Co. (www.newbelgium.com) has grown to occupy a 50-acre campus in Fort Collins, Colo., with multiple brewing processes, water processing systems and building and facility management systems, which are monitored and controlled by more than 10,000 digital and analog I/O points that are organized into eight control zones. Seven of these zones, including the brewhouse, filtering, malting, yeasting, cellaring and other complicated brewing processes, are controlled by Opto 22's SNAP programmable automation controllers (PACs), which monitor and regulate oven temperatures for drying and roasting the grains, machines that crush and mash them, and water and resting brew mixture temperatures. To help power all its brewing and support operations, New Belgium has used a series of wind turbines for more than 10 years.

Wireless Field Devices Are Shipping, but Adoption Questions Remain
"The importance of WiFi, VoIP and other backbone technologies is huge because Wi-Fi is 'wireless Ethernet,' a well-established, widely deployed and proven networking standard. WiMax is essentially high-powered Wi-Fi, and VoIP is, as the name implies, Internet Protocol (IP)-based. Thus, any industrial application that uses Ethernet, wired or wireless, as the physical medium, and IP to effectively broker all the requests between the application layer and the physical layer has a far greater ability to integrate into existing applications and play nice with all the other industrial technologies and networks that are out there."

PACs & I/O Go Wireless
The automation industry increasingly finds wireless attractive, and for several reasons. Running a wired network incurs significant labour and material costs, while wireless networks cost far less. Wireless offers connectivity for remote areas or areas not currently served by wired networks.Wireless controllers and I/O can manage devices and processes even in inaccessible areas, or areas where network wiring is difficult or impossible to install. And wireless can offer a way to provide proof-of-concept for a new project before incurring the expense of a wired network.
