Most plants already have the paperless MES to capture downtime and quality context — they just haven’t forced it to survive shift change. Here’s a step-by-step protocol to stop “it ran fine” from hiding real problems.

With edge hardware now cheap enough to run per line instead of per plant, the hard decision isn’t edge vs. cloud anymore — it’s how you manage fifty devices without fifty tag structures. Here’s a practitioner’s framework for evaluating edge historian appliances.

Every MES suite now sells a digital twin module, and most plants are buying the wrong tier — either overbuilt physics engines for questions a spreadsheet could answer, or static 3D models for questions that need real simulation.

As Proficy renewal cycles hit their first full year since the GE Vernova spinoff, plants are being offered pricier tiers bundled with AI and analytics features. Here’s how to tell what’s new from what’s relabeled, before you sign.

ISA-95 Part 4 defines a specific, relational data model for production genealogy — but most MES “genealogy” features were built before anyone checked. Here’s how to tell the difference before it costs you at audit time.

CISA’s KEV remediation timelines were built for IT patch cycles, not PLCs that can only come down during a scheduled outage. Here’s a practical framework for documenting compensating controls that satisfy auditors and insurers without pretending the patch happened.

Every MES vendor is bundling a generative AI copilot, and most of them assume a cloud LLM. A growing body of plant-floor evidence says the smarter default is a small, fine-tuned model running on the edge box next to the line.

Higher-payload, higher-speed cobots have turned safety design from a fencing decision into a distributed motion-control problem. Here’s a practical framework for validating a shared safety zone across TwinSAFE, GuardLogix, and Safety Integrated controllers on the same line.
