Whether you are integrating one programmable controller, or many, into a system, there are mistakes that you'll want to avoid in your programmable controller startup. This article helps you avoid those areas where mistakes are bound to happen and talks about the five most common planning and installation errors that cause poor operation.

PIDs (proportional, integral, derivative) play a pivotal role in making it easier to regulate and control things. Each part of a PID loop functions as a tool of adjustment, with each having a specific purpose. This article talks about loop basics, how controllers work, techniques for fine tuning, and PID loop applications.

PLCs (programmable logic controllers) are sophisticated devices with many capabilities. Originally they simply replaced relays in machine control. The smaller, simpler PLCs are best for replacing relays and performing machine control function in a minimal space. Today's micro PLCs offer many functions, such as math calculation, jumps, subroutines, and analog control.

Control system technology is quickly migrating toward an open concept where networks can accommodate factory devices from a multitude of manufacturers. This article talks about two new open networks that offer a big step forward in this move toward distributed machine control.

This article discusses how a long standing conveyor jam-up problem on a cookie production line was solved by installing a new electronic synchronizing controller. Almost 200 lbs. of cookie were scrapped every day due to production line breakage before the fix.

Field multiplexers can save both wire and money by collecting data from widely dispersed points throughout a plant, helping to keep tight control over manufacturing operations. Multiplexers can do away with the need to run dedicated wires from point to point.

This article discusses how high-speed winding problems can be solved by dedicated controls. A microprocessor-based winder control works by changing its gain during operations. This results in the improvement of roll quality while winding paper at up to 2,000 fpm with a 17:1 build-up.

"Caring For Water-Soaked Controllers" is an article that deals with the question, "Can water-soaked motor controllers and adjustable-speed drives be used once they have been soaked by flooding waters?" The answer, according to the article, is that PT devices soaked by flood waters need not always be scrapped. Pointers are given for rejuvenating motor starters and adjustable-speed drive controllers. An excellent article for those in the Midwest or anyone in a similar situation.

Fuzzy Logic, FL, is a technique based on microprocessor capabilties that enable control devices to think more like humans. As a result, you can automate systems that previously required constant human montoring. Fuzzy Logic can make decisions based on imprecise data by mimicing the human mind. This article gives alot of information on this topic.

The proliferation of sensor-actuator buses (also known as device-level buses) has blossomed in recent years to where the user has a multitude of choices. This article takes a look at what's behind this proliferation of networks and offers tips that will make your bus selection easier.
