Did you know that over 500 articles and tutorials are now freely available on ACC Automation? That’s right—more than a decade of accumulated PLC programming knowledge, HMI design guides, communication tutorials, and hands-on examples waiting for you to explore, all without spending a dime. Whether you’re a complete beginner trying to understand your first rung of ladder logic or a seasoned controls engineer looking for that one specific Modbus configuration tip, there’s something here for you.
As we wrap up another year of learning PLC programming at ACC Automation, we’re excited to reflect on the progress, innovations, and milestones we’ve achieved in 2025. This year has been filled with growth, learning, and pushing the limits of industrial automation.
Let’s highlight some key events from the year. ACC Automation Review
January – February: Node-RED Integration Takes Center Stage – ACC Automation Review
We kicked off 2025 with extensive coverage of the Click PLUS C2-NRED module. This Node-RED integration opened up incredible possibilities for connecting PLCs to IoT platforms, dashboards, and cloud services.
The series covered everything from basic installation to advanced node configurations and Modbus TCP communication between Node-RED and both the BRX Do-More and Click PLCs. For those looking to bridge the gap between traditional PLC programming and modern IoT connectivity, these tutorials provided a practical pathway forward.

March – April: Modbus Communication Deep Dives – ACC Automation Review
Spring brought comprehensive Modbus communication tutorials. We explored RS-485 serial connections, demonstrating proper wiring techniques and configuration settings that many beginners struggle with. The Click PLC Modbus RS-485 series became one of our most-referenced resources.
We also continued expanding the Click PLC series with topics ranging from remote I/O configurations using Stride Field modules to the BX-MBIO Modbus TCP/RTU remote I/O controller. Real-world communication scenarios that control engineers face daily were addressed with step-by-step solutions.
May – June: PLC Simulators and Baggage Claim Automation – ACC Automation Review
In May and June, we doubled down on the importance of PLC simulators for learning. The posts emphasized how simulators can reduce programming development time by up to 50 percent—a claim backed by real experience.
The airport baggage claim automation series captured the reader’s attention. Globally, airlines handle over 4 billion bags annually, with 99.6 percent arriving on time. We explored how PLC programming enables this, walking through the design and programming of an automated baggage handling system. The troubleshooting follow-up addressed sensor issues and PLC tweaks that maintenance technicians encounter in the field.

July: PLC Programming Myths Exposed- ACC Automation Review
July tackled something different—the myths and misconceptions that hold beginners back from mastering PLC programming. We addressed common fears and misunderstandings that prevent people from diving into industrial automation, providing clarity and encouragement for those just starting their journey.
The free Click PLC software post reminded everyone that professional-grade programming tools don’t always come with professional-grade price tags. AutomationDirect’s commitment to free software downloads continues to lower barriers for learners worldwide.

August: Timers, Static IP, and Why Simulators Matter – ACC Automation Review
August focused on foundational topics that every PLC programmer needs to master. The Click PLC timer tutorial walked through practical applications using a story-driven approach—Mark, a veteran automation engineer dealing with conveyor bottlenecks, served as our guide through timer configuration and troubleshooting.
We also covered static IP assignment on the Click PLUS PLC, an essential skill for anyone setting up networked control systems. The simulator advocacy continued with content explaining why every beginner needs hands-on practice before touching real hardware.

September: PLC Scan Cycles and Ladder Logic Fundamentals – ACC Automation Review
September dove deep into the mechanics of how PLCs actually work. Understanding scan cycles—how PLCs process inputs, execute programs, and update outputs in a continuous loop—separates proficient programmers from those who struggle with timing issues and unexpected behavior.
We addressed the most commonly asked ladder logic questions and explored why specific logic patterns confuse beginners. These fundamental concepts apply regardless of which PLC brand you’re working with.

October: AI Meets PLC Programming – ACC Automation Review
October marked a significant milestone—exploring the intersection of artificial intelligence and PLC programming. The Claude AI post investigated whether modern AI tools could successfully assist with PLC programming tasks. This emerging technology presents fascinating possibilities for how we’ll develop and troubleshoot control systems in the future.
Digital twins also received attention, examining how virtual replicas of physical systems can transform factory operations. The Machine Simulator software suite continues to provide hands-on digital twin capabilities for learners and professionals alike.

December: Power Supplies, Wiring Best Practices, and Ferrules – ACC Automation Review
We’re closing out 2025 with essential infrastructure topics. The PSRS-24-60 power supply post addressed why PLCs die without proper power—covering galvanic isolation, voltage regulation, and the critical role power supplies play in control system reliability.
Wiring best practices received dedicated attention, particularly the use of ferrules with stranded wire. This seemingly simple topic prevents countless field failures. When stranded wire meets screw terminals without proper termination, connections loosen, strands break, and systems fail. Ferrules elegantly and inexpensively solve this problem.
Ethernet switch selection for industrial networks is also currently under development, addressing the networking infrastructure that ties modern control systems together.
Why Your PLC Dies Without the Right Power Supply!
Looking Forward to 2026
As the year draws to a close, we’re already planning next year’s content.
Expect coverage of the Productivity Mini PLC series—compact controllers with built-in I/O that represent an exciting evolution in the Productivity family. The C-More CM5 HMI series will continue receiving attention as we explore its enhanced capabilities and integration options.
Perhaps most exciting is our planned exploration of AI with Model Context Protocol (MCP) for industrial automation applications. The convergence of artificial intelligence and traditional control systems opens possibilities we’re only beginning to understand.
2025 was filled with growth, innovation, and meaningful connections at ACC Automation. We introduced practical tutorials, shared hands-on programming examples, and continued building resources that help people learn industrial automation without expensive training courses or equipment investments.
As we enter 2026, we remain committed to supporting readers and viewers in their automation projects. Thank you for being part of the ACC Automation family. Here’s to another year of success and progress!
As always, we will answer your questions and applications so you can quickly implement your control solution.
