Who doesn’t love going to the beach? I know I do, a least for the first few days. Then the sand begins its advance and outflanks my defenses. Children are its ally, and before you can say, “Don’t shake that!”, it’s everywhere. But besides the sandy blitzkrieg, the beach does offer a lot of fun. One activity that everyone seems to enjoy, at least where I’m from, is heading to the beach late at night with flashlights and nets to catch sand crabs. You may know them as ghost crabs, but they are impressively quick and built for their environment. For one, they blend in perfectly with the sand. As mentioned, they are super quick and I’ve read they can reach speeds up to 10mph! For food, they can survive on almost anything including clams, decaying material, and, if needed, other crabs. Their eyes can swivel 360° to detect predators or a meal. To escape predators, they hide in deep burrows they’ve dug in the sand or make lightning-fast escapes into the water. But for all their preparedness, it’s obvious they never expected a child, at night, with a net and a flashlight. This just goes to show that even the best laid plans and preparation can go awry and have to be modified in an instant.

This issue of NOTEBOOK is loaded with informative articles such as our Tech Brief, which looks at some important PLC fundamentals. We also have a great Cover Story on how recent advancements have expanded the role of PLCs in enterprise data collection and analysis. The User Solutions show how ProductivityOpen was used to increase heat exchanger efficiency and how ABS-certified Productivity PLCs are helping modernize the luxury yacht industry. Our PLC Speaking section discusses a common coding technique used to program package tracking applications. For information about exciting events happening in and around AutomationDirect, take a look at the Business Notes. In this issue, you’ll also find information on our newest products, such as the new CLICK PLUS PLCs, IronHorse ACN Series NEMA 4X AC drives, the NITRA Pneumatic Automation Link (PAL) system, Saginaw enclosures, Datalogic safety laser scanners, and more. As always, the Break Room is stocked with fun and challenging brainteasers, so give them a try and see how many puzzles you can solve.
Zig or Zag The factory manager wants to know how many routes there are for the AGV (Automated Guided Vehicle) in the lower left corner to get to the charging station in the upper right (see the diagram below). The AGV must always travel along the lines shown such that it gets closer to the…
Old-fashioned automation architectures suffer from complexity and slow communications. See how today’s PLC advances boost simplicity and performance. Damon Purvis, PLC Product Manager at AutomationDirect, an article for the April 2021 edition of Machine Design. The article is titled The PLC Breaks Out! and it looks at how modern PLCs can streamline classically rigid architectures…

PLCs play a major role when it comes to material or package handling operations. Conveyors, motors, drives, object detection sensors and of course controllers are used quite often when it comes to delivering your suitcase to the right airplane or getting the laptop you ordered to the right delivery truck. But how would you go…
With PLC control, it’s important to understand the sequence of operations for the CPU. Some may think when an output is set to ON in the ladder code, that this output change is immediately reflected in the output card. Or that when an input is activated, the CPU instantly sees it. While it may seem…
Two of the most important fundamentals to understand when it comes to sensors is sinking and sourcing circuits. To properly wire your control device, you need to first know whether the sensor you are using is switching the positive or negative connection. For AC (alternating current) sensors, this is not an issue since AC power…
For a better understanding of PLCs, let’s take a closer look at one of the fundamentals of automated control – logic circuits. Electrical components can be hardwired in a way to allow certain decisions to be made electrically. They can provide physical “If, then” statements that systems can use in their decision making. “If this…
