ACC Automation: PLC & Industrial Control Learning
Practical Tips and Techniques
A one-shot in the PLC will turn an output on for one scan. This is used to trigger events that should only happen once. An example of this would be to increment a value in memory. If a one-shot is not used, then every scan of the PLC will increment the value. What is a … Read more
This post is a further follow-up from my original ‘Here’s a Quick Way to Understand PLC Inputs and Outputs.’ There are two different kinds of PLC outputs, Discrete and analog. Discrete outputs are either ‘ON’ or ‘OFF’; 1 or 0. You can think of them as a single light bulb. Analog outputs have a range … Read more
We will look at how to troubleshoot a plc racing condition. Two examples are explained in racing conditions in the PLC. The PLC will update only at the end of the program logic. Items set will not happen until the I/O is refreshed. How to trigger events when you want them is discussed. Your control … Read more
PLC programming involves both direct and indirect addressing. Direct address programming involves writing each ladder logic rung to do the operation required. We often forget about using powerful indirect addressing to solve our logic. Indirect Addressing – Faster PLC Program The below-animated picture will show a simple example of using indirect addressing. This will use … Read more
Learning programmable logic controllers (PLC) include understanding of the basic components, language, numbering systems, program development. PLC Basics will help in your learning of the programmable logic controller. If this is your very first time programming a PLC, we suggest you check out our beginner’s guide to programmable logic controllers. Hardware and Software – PLC … Read more
A collection of random thoughts on PLC programming and doing more than just basic logic and making your program intuitive. PLC programs usually control the logic between the inputs and outputs. If this turns on and that is not on, then this output is on, blah blah blah. Programmable logic controller programs can go far … Read more
Here are the top 7 problems and concepts beginners struggle with using ladder logic (Ladder Diagram). Ladder logic is a programming language used in PLCs, and it is based on the graphical representation of electrical relay logic circuits. Many beginners struggle with ladder logic because it requires a different mindset than traditional programming languages like … Read more
