In the world of Industrial IoT (IIoT), reliability is everything. Sensors must read accurately, actuators must respond predictably, and communication must flow without surprises. On the embedded side, this means precise control of hardware resources, minimal overhead, and code that behaves deterministically. Enter Embedded Rust and RTIC—a pairing that gives engineers both safety and performance without compromise. Why Embedded Rust? Rust’s focus on memory safety, zero-cost abstractions, and strict compile-time checks makes it ideal for embedded systems. Unlike C, Rust prevents entire classes of bugs like null pointer dereferences or buffer overflows. When your MCU has just a few kilobytes of RAM, these protections are not optional—they’re essential. ...

1. Introduction I come from a networking background. For years, my world revolved around packets, routing tables, latency, and uptime. Over time, it became clear that the boundary between IT and OT (Operational Technology) was becoming less rigid as industrial systems moved onto standard IP networks. Networks were no longer just carrying business traffic — they were increasingly responsible for transporting sensor data, telemetry, and control signals from the physical world. That realization pushed me toward Industrial IoT (IIoT) and, inevitably, embedded systems. ...

Design Science is a research methodology and problem-solving framework that focuses on the creation and evaluation of artifacts designed to solve real-world problems. Rather than studying systems passively, Design Science emphasizes active construction, experimentation, and rigorous evaluation. Its principles have traditionally been applied in information systems and software development, but they are equally relevant to modern embedded and IIoT engineering. In complex engineering domains — including embedded systems, IoT, and distributed sensor networks — the challenge is not just writing code or assembling hardware. It’s about systematically creating artifacts that solve practical problems effectively, reliably, and efficiently. ...
