MT5000 SERIES. WORLD’S FIRST SIL2/SIL3 CERTIFIED GUIDED WAVE RADAR LEVEL TRANSMITTER THE NEW LEVEL OF SAFETY With over 12 years experience in critical level measurement of liquid, interface and bulk solids level, the MT5000 Series is now the world’s first SIL2 certified guided wave radar. Certification to the stringent IEC61508 requirements allows users to apply the MT5000 Series in Safety Instrumented Systems (SIS) requiring up to SIL2 and SIL3 capable components with confidence. Proper use of the MT5000 Series Guided Wave Radar in a Safety Instrumented Function (SIF) also eliminates the need for “prior use” justification as well as possible requirements for redundant measurements in the control system loop. Certification by an independent agency (Exida) takes IEC61508 conformance to a new level by performing a thorough impartial evaluation of the MT5000 Series hardware & software design, testing, diagnostics, operational hours, record keeping and manufacturing practices for full conformance to IEC61508 criteria.

R E S O U R C E S Where to Go for Help with Your PLCs and PACs Control’s Monthly Resource Guide Every month, Control’s editors take a specific product area, collect all the latest, significant tools we can find, and present them here to make your job easier. If you know of any tools and resources we didn’t include, send them to wboyes@putman.net, and we’ll add them to the website. PACs FOR COMMUNICATIONS AND DATA HANDLING cONTROL w w w.controlglobal.com Many process control applications require much more than just real-time control, and extensive communications and data handling can tax the functionality of PLCs. In these instances, a programmable automation controller (PAC) can be a good fit. Most PACs are derived from the PC world, hence, their relative strength when it comes to communications and data handling. Control’s senior technical editor, Dan Hebert explores some PAC basics. Go to www.controlglobal.com/articles/2008/026.html for his insights. PLCs, PACs AND POWER OVER ETHERNET Advantech 880/205-7950 w w w.advantech.com Field level wiring used to be very simple. A sensor was either powered or passive. But, when networking PLCs and PACs coming into the control system network became both practical and popular, engineers started thinking about how to provide power over the same set of wires as the network connection. This white paper discusses how Power over the Ethernet is fast becoming the standard. The link to the free registration page is http:// tinyurl.com/47mvsqm. DESIGNING PLC MODULES Analog De vices w w w.analog.com This webcast deals with the requirements and challenges associated with the design and implementation of analog input/output modules used in industrial control applications, with a particular focus on programmable logic controller (PLC) modules. Design and applications tips and techniques will be presented, and examples of Analog Devices’ solutions will be discussed. A direct link to the webcast is at http:// tinyurl.com/4kg28z8. GUIDE TO PLCS AND OTHER DEVICES work .com w w w.work.com This link-rich page provides the user with basics for determining whether you need a programmable logic device, tips for finding training, and lists of available sources. A direct link to the pages is at http://tinyurl. com/4jlodm5. PLC/PAC PDFs pdf4me.ne t w w w.pdf4me.net This site contains dozens of downloadable PDFs on a variety of PLC and PAC subjects, including “Understanding PACs,” “A Controller System for Industrial Automation,” “The Design of a Portable Programmable Logic Controller,” “Introduction to Programmable Logic Control,” “Logic Control Systems” and “Embedded and Industrial Automation.” Each selection offers both a full download and a preview page to aid in selection.

Greg Shinskey discusses the power of external-reset feedback in this article from Control magazine. He says that preventing windup requires reconfiguration of the controller, and external-reset feedback is the most satisfactory method of accomplishing it. The article includes techniques and equations for this process. The direct link is at http://tinyurl. com/4lwngsg. PLC/PAC TUTORIAL The PLC Tutor w w w.theplctutor.com If you have the desire to learn about programmable logic controllers and/or programmable automation controllers, or if you need a refresher or some tutoring, then this is the place to go.
