If you’ve worked on both a factory floor and a hobby electronics bench, you already know PLCs and microcontrollers can look like they do the same job. Read inputs, run logic, drive outputs. But the …
If you’ve spent any time around industrial automation, you’ve heard these three acronyms thrown around like they’re interchangeable. They’re not. DCS, PLC, and SCADA solve different problems, and confusing them leads to expensive design mistakes, …
If you work anywhere near PLCs, DCS platforms, or control panels, you’ve probably seen the letters ISA come up, usually attached to a training course, a badge on someone’s LinkedIn profile, or a line item …
Ladder logic gets all the attention in PLC training courses, but anyone who has scaled a project past a few hundred rungs knows why Structured Text (ST) exists. ST is the IEC 61131-3 high-level language …
Ladder logic is still the most widely used PLC programming language on the plant floor, and the fastest way to learn it isn’t by memorizing instruction sets. It’s by studying real rungs that solve real …
If you’re building a career in industrial automation, you’ve probably noticed that job postings for PLC programmers, controls engineers, and automation technicians rarely agree on what qualifications they actually want. Some list a degree. Some …
If you’re weighing a move into industrial automation or you’re already in the field and wondering whether you’re being paid fairly, the honest answer is it depends heavily on where you sit on the experience …
If you’ve ever watched a bottling line, a water treatment plant, or an assembly cell run itself with almost no human intervention, you’ve watched a PLC at work. Somewhere behind that automation is a programmer …
Modbus TCP runs somewhere in almost every industrial facility you’ll ever walk into. PLCs, HMIs, RTUs, VFDs, and building management systems all lean on it because it’s simple, well-documented, and universally supported. But that same …
For decades, industrial automation has run on a patchwork of incompatible protocols. A plant floor might mix PROFINET on one line, EtherNet/IP on another, and Modbus TCP holding together a handful of legacy devices with …
