Notes from the people building it.

Engineering deep-dives, architecture decisions and the reasoning behind them.

How Long to Keep Industrial Data, and at What Resolution

Retention is usually decided by whatever the historian defaulted to, which is the wrong way round. What the questions you will ask later actually require, and where downsampling destroys the answer.

Why Operators Ignore Your Alarms

An alarm system that produces more signals than a person can act on has not made the plant safer; it has trained the control room to stop reading. What goes wrong, and the specific fixes that reverse it.

How to Read a Sensor Datasheet

The headline accuracy figure is the least informative number on the page. What the conditions clause is doing, why drift usually matters more than accuracy, and the specifications that are absent on purpose.

Designing for a Site You Cannot Visit

When a service call costs more than the device, every design decision changes. Power, communications, failure modes and diagnosis all get re-argued from the assumption that nobody is coming.

What Cold-Chain Monitoring Actually Has to Prove

A temperature logger records data. A compliant cold chain produces evidence, which is a different and much harder thing. What the record has to survive, where designs usually fail an audit, and how to build one that does not.

Containers on the Plant Floor: What Changes When a Gateway Runs Docker

Running containers on an industrial gateway solves real problems and creates a new class of them. What genuinely improves, what quietly becomes your responsibility, and the decisions worth making before the first deployment rather than after.

What the Cyber Resilience Act Asks of a Connected Product

The regulation is often summarised as security requirements for connected devices, which is true and not actionable. What it actually obliges a manufacturer to build, to document, to report and to keep doing for years after the sale.

Why Vision Inspection Works on the Pilot Line and Fails on the Second Shift

Almost every disappointing inspection deployment fails for the same handful of reasons, and none of them are the model. What changes between the demonstration and the running line, and how to design so that it does not matter.

Why Predictive Maintenance Pilots Stall Before They Scale

The technology works in the demonstration and disappoints in the plant, and the reasons are consistent enough to plan around. What the pilot proved, what it did not, and the failure modes that only appear at fleet scale.

Private 5G or Wi-Fi on the Plant Floor: How the Choice Is Actually Made

The comparison is usually argued on throughput, which is the one specification that rarely decides it. What separates the two in practice is who owns the spectrum, how the network behaves at the edge of coverage, and what happens when a device roams.

Where Should Inference Run: Gateway, Controller, or Cloud?

Edge or cloud is the wrong first question. A practical way to place a model, built around six constraints that decide the answer before any hardware is chosen, and the mistakes that come from optimising the wrong one.

What Time-Sensitive Networking Actually Guarantees on a Plant Floor

TSN is sold as deterministic Ethernet, but the guarantee is narrower and far more conditional than the phrase suggests. What the standards bound, what they leave alone, and what has to be true of your network before any of it holds.
