As the demand for smarter, more connected systems continues to rise, PLCs are evolving beyond their traditional boundaries. What was once considered a rigid, low-level controller is now starting to behave more like a modern computer—bridging the gap between industrial automation and full-stack development. I experienced this first hand recently as I had a project where I needed to pull data from a third party system. The catch? The data was only accessible via a REST API. Instead of routing everything through a middleware PC, I implemented an HTTP GET request directly from the PLC. The response came back in JSON format, which I parsed on the controller to populate target parameters in real time—no external hardware or conversion layer needed. Today’s PLCs are capable of much more than deterministic scan cycles and I/O control. A lot of PLCs are adopting items we see in a regular software development setting: - HTTP requests can now be sent and received directly from many brands of controllers - JSON parsing is becoming supported across several PLC platforms - RESTful APIs can be integrated to communicate with cloud services or MES/ERP systems through PLCs - Secure communication over protocols like MQTT and OPC UA is becoming more common - File handling, string manipulation, and even structured object handling are part of the toolbox - Some platforms support object-oriented programming and event-driven architectures Why does this matter? Because the modern factory is no longer isolated—it’s part of a broader ecosystem. Smart manufacturing, Industry 4.0, and IIoT demand seamless data flow between machines, systems, and people. As system engineers, we’re entering an exciting time where the roles of industrial control and software development are blending. This shift opens up new possibilities, but it also means we must continue expanding our skill sets beyond traditional methods of PLC programming. P.S. the controller I used for those HTTP requests mentioned earlier was an AutomationDirect BRX Model PLC. #IndustrialAutomation #PLCs #IIoT #Industry40 #AutomationEngineering #SmartManufacturing #PLCProgramming #OTmeetsIT #ControlSystems #JSON #APIs #EdgeComputing

🛠️ Beyond Ladder Logic: Conventional Programming Languages Powering PLC & SCADA Work While IEC 61131-3 languages (like Ladder Logic and Structured Text) are standard for PLCs, the modern automation landscape demands more versatile and high-level languages—especially for SCADA systems, custom interfaces, IIoT integrations, and cloud connectivity. Here are some of the most commonly used conventional programming languages you’ll find in real-world industrial projects: 💻 Python – Widely used for scripting, analytics, testing, OPC UA clients, and SCADA platforms like Ignition. Ideal for rapid IIoT prototyping and integration. 🌐 JavaScript – Essential for web-based HMI development, Node-RED flows, and custom dashboards in SCADA or IIoT applications. ⚙️ C/C++ – Found in embedded controllers, industrial firmware, and performance-critical edge devices. ☁️ SQL – Integral to SCADA historians, data logging, and analytics platforms for querying process data in real time. 🔗 Java – Still popular in some SCADA platforms (like Ignition) for developing modules or custom scripting. 🔐 Shell/Bash & PowerShell – Used in automated deployment, system monitoring, backups, and cybersecurity hardening in OT/IT converged environments. 🧠 Go, Rust, and others – Emerging in edge computing and high-performance industrial gateways. In short: today’s automation engineer is part controls programmer, part software developer. 💬 Curious to hear from others—what non-IEC language do you use most in your automation work? #PLC #SCADA #Python #JavaScript #IndustrialAutomation #IIoT #EdgeComputing #OPCUA #IgnitionSCADA #AutomationEngineering #ControlsProgramming #SmartManufacturing

AI agents and physical AI are shifting industrial automation from equipment supply to autonomous, self-optimizing systems. The most mature vendors are moving from pilots to production, with robots navigating complex environments and digital twins optimizing the value chain. This CB Insights brief gives a good view of where the top 20 industrial automation companies stand on AI maturity. Three key trends. 1. Leaders like Siemens Industry and ABB are linking AI systems across design, logistics, manufacturing, and maintenance creating compounding benefits. 2. Optimization dominates near-term priorities, while digital twins are emerging as the backbone for connecting hardware and software. 3. Partnerships with tech companies like Microsoft, Google, and Nvidia are essential, but they create new dependencies that must be managed. Siemens at the top of the ranking, combining copilots, edge platforms, and digital twins. Its work with Microsoft and Nvidia expands capabilities but increases reliance on external tech. Honeywell takes a more focused approach, embedding AI into devices and workflows. Its Qualcomm partnership highlights product-level integration over broad system building. ABB advances through its OmniCore platform and acquisitions such as Sevensense and SensorFact, blending robotics, software, and energy management. Schneider Electric pushes AI in energy management, using digital twins and partnerships with Nvidia, Microsoft, and Itron to extend from factory optimization into grid intelligence. The path forward in industrial AI is moving beyond pilots or isolated tools. It will depend on how well vendors embed AI into their platforms, link technologies across domains, and balance the benefits of external partners with the need for strategic independence. Those that will get it right will turn AI from experimentation into durable advantage. Just as critical is how their customers adopt these technologies. Industrial firms must shift from isolated use cases to embedding AI in design, production, energy, and logistics. Success requires not only advanced tools, but also the data, skills, and processes to make AI scale in complex operations.

We are witnessing a meaningful advance in Embodied Intelligence that directly impacts industrial automation. A recent study, “Human-AI Co-Embodied Intelligence for Scientific Experimentation and Manufacturing” (Lin et al., 2025), demonstrates a cyber-physical-human loop where agentic AI, multimodal sensing, wearable interfaces, and adaptive control jointly guide real manufacturing tasks in real time. 📄 https://lnkd.in/gWYTC4zQ The system fuses human motion data, sensor-actuator signals, and process models to generate context-aware reasoning, real-time planning, corrective feedback and higher accuracy than general multimodal LLMs in flexible-electronics fabrication. For us, the implications are clear: Physical AI will require tightly integrated perception-reasoning-control stacks, human-robot collaboration, and safety-critical robustness to enable the next generation of intelligent manufacturing, adaptive automation, and the Industrial Metaverse. #PhysicalAI #EmbodiedAI #IndustrialAI #SmartManufacturing #CyberPhysicalSystems #HumanRobotCollaboration #Robotics #AgenticAI #DigitalTwin #Industry40 #ManufacturingInnovation #OperationsIntelligence #AdaptiveAutomation #WearableIntelligence #SensorFusion #ControlSystems #siemens

Just wrapped up a fun engineering challenge: building a constraint-driven optimization engine for complex axis assignment problems — the kind we bump into all the time in industrial automation, controls, and high-precision motion systems. The idea sounds simple: match a set of movable axes to a set of target positions. The reality: every axis has its own travel limits, allowable region, spacing rules, and mechanical ordering… and every invalid combination needs to be avoided. To keep it clean and rock-solid, the engine does a two-stage approach: 1️⃣ Smart assignment It evaluates feasible permutations, enforces mechanical monotonicity (no crossing), respects per-axis limits, honors pairwise spacing rules, and selects a contiguous block of axes — no “holes” allowed. The best solution wins based on a cost model that favors stable, centered, predictable motion. 2️⃣ Intelligent parking Unused axes are placed safely outside the active region. Then a refinement step nudges those parked positions just enough to satisfy limits, clearances, and spacing rules without disturbing the optimized core. Along the way, the system reports every violation, cost component, and decision path — transparent, debuggable, deterministic. It’s designed with Inductive Automation’s Ignition, Python, real-world PLC constraints, and the kind of control-system edge cases you get from Allen-Bradley, motion rigs, and industrial equipment in mind. Perfect fit for heavy-duty production environments. Really proud of how this one came together — blending optimization theory, practical controls engineering, and real-world mechanical constraints into one clean engine. #IndustrialAutomation #ControlsEngineering #Ignition #InductiveAutomation #PLC #AllenBradley #Optimization #ManufacturingTech #MotionControl
