As the title suggests, I'm looking for something to help me learn the basics of PLC programming. We're looking to develop the ability to do it in-house rather than wait for a contractor to come in ...

Industrial automation technologies have made manufacturing processes increasingly more efficient. Programmable logic controllers (PLCs) are commonly used in industrial automation, and many of these ...

And, the ability to monitor PLC logic in ladder diagram format also made troubleshooting easier for those already familiar with relay-based control systems. Although there are many higher-level ...

Fig. 2. Ladder logic uses memory locations rather than hard-wired logic. For the program shown in Fig. 2, we took the relay logic’s ladder diagram from Fig. 1 and duplicated it with ladder logic — no ...

PLC Counters and Timers provides an overview of the functions of counter and timer instructions in a ... be familiar with the different applications for counter and timer instructions and how the ...

Each of these objects can interact with the ladder program of the connected PLC either by use of “tags” (discussed in earlier articles in this series) which are variables with user-friendly names such ...

Instead, he pulled the PLC source data to an edge computer running artificial intelligence IoT software, which added sensor data and operational parameters. Without getting into the ladder logic, they ...
