If your facility or workplace uses a PLC, it’s almost certainly because it must interface with physical input and output devices. What kinds of I/O modules exist, and how can you tell the difference? Out of all the sub-system components that make up a PLC, and throughout the world of computers in general, the I/O … Read more
Logic is critical for industrial control, and it usually looks like ladders, function blocks, or structured text. I/O controllers are designed to automate simple logic tasks and data functions. Modern PLCs are capable of many thousands of tasks, including communication across many protocols, setting algorithms for motion and vision systems, and performing incredibly complex arrangements … Read more
An age-old debate in PLC programming: investigating the uses and caveats of latching software commands versus seal-in ladder logic for industrial control applications. One of the most popular programming languages used with industrial automation controllers today is called ladder logic, following in the footsteps of the previous method of control which used interlocking electrical relays. … 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
Every automated cell requires a ‘brain’ in order to achieve the required tasks. How do you determine the necessary I/O, communication protocols, and processor necessary for controlling your system? Previously, we have covered the initial steps of choosing the proper automation project and getting started with the initial connections to the real world with sensor … Read more
There are multiple methods for mapping inputs and outputs to an industrial robot. In this article, we cover two of the most popular methods: letting the robot or the PLC control the I/O signals. There is one unavoidable question to ask during your next robotic design, no matter what brand of robot is used: you … Read more
Networked remote I/O allows us to work with a machine center separately from the rest of the system, and drop the solution right in place. If you are worried about the distance between machines or the age of an old machine becoming a hindrance to bringing your operation into the 21st century, don’t worry. Computer … Read more
