What causes mechanical failure? Learn about three major sources of failure points in any mechanical assembly and a few tips to minimize failure. Mechanical motion systems are prone to problems that require regular maintenance. If properly maintained, then costly repairs can sometimes be avoided. Most of the preventive types of maintenance revolve around trying to … Read more
For most systems, there are various languages meant for specific purposes, including Function Block, Sequential Charts, and Structured Text. By far, the most common programming language for PLCs consists of rungs of if-then logic, similar to an electrical line diagram, going by the name of ‘Ladder Logic.’ Many programmers have quite likely been exposed only … Read more
This article explores what tools can be used to predict and prevent costly mechanical breakdown events occurring from heat, vibration, or humidity. Mechanical failure in a machine can lead to lengthy and expensive downtime. Although the problems may be easy to spot when they occur, the replacement of failed components can take a longer time … Read more
The wide variety of sensors available for control systems leads to the daunting task of selecting the proper device. Different types of machines and programmable controllers require careful attention to detail when selecting appropriate sensors. Nearly every modern machine that needs to be repaired or upgraded has very specific requirements of what sort of data … Read more
The following will take a step back from IoT and machine data to see how engineering practices such as material selection and CAD can do more with less. IoT, connected devices, and other technologies are driving digital manufacturing. However, accelerating design cycles and shorter product life cycles can create stress on production lines. Starting a … Read more
Machine safety design can be a daunting task with all the different safety devices on the market today. Choosing the correct device for your design can be made easier by understanding when to use the proper device. Machine Safety Automated equipment can be a simple pneumatic cylinder or an assembly of different automation components all … Read more
Robots as a service (RaaS) can open the door to automation for small to mid-sized companies that are looking to automate a process without a large upfront capital investment. Figure 1. Autonomous guided vehicles (AGVs) are common in warehousing applications. What is RaaS? The software industry, particularly cloud computing, has been developing products as a … Read more
Why do we need to use PNP sensors in certain applications, and which markings and diagrams allow us to identify these devices? Integrating sensors into control systems can be a tricky process. Not only is there a wide diversity of sensor types, but there are also competing electrical characteristics I love programmable control systems. They … Read more
Many PLC commands are well-known to programmers, including contacts, coils, timers, and counters. But a less-common instruction is the one-shot, capable of harnessing the incredible processing speeds in a CPU. One-Shot Functions In a previous article, I wrote about how to use timers in ladder logic. A typical next step is to discuss counters, being … Read more
Sensors with timer functions advance modern automation systems, enhancing the precision and flexibility of in-process controls to ease the strict requirement for an external, clock-based logic CPU. Modern, sophisticated sensors often include integrated timing capabilities, allowing for precise coordination of actions based on input signals. These sensors offer a range of functionalities, including on delay, … Read more
