Node-RED is running in factories, renewable energy systems and smart buildings all over the world. Most of the industry has no idea who built the protocol packages that made it production-worthy.

Klaus Landsdorf, CEO of Iniationware and creator of PLUS for Node-RED (P4NR), joins Phil Seboa and Ed Fuentes for ten years of industrial Node-RED contribution. He first looked at Node-RED in 2015 as a favour to Schneider Electric France, found that queued Modbus messages fired as fast as the runtime could send them, and rebuilt the package from scratch so it could be trusted on a factory floor. Ten years and a thousand-plus commits later it is one of a small number of Node-RED packages carrying a certified designation, and nothing ships below 92% code coverage.

Topics covered:

- Rebuilding Modbus for real industrial timing, and the quality gate that followed

- OPC UA built as an educational package rather than an abstraction

- ISA-95 as a 30-year framework that already describes unified namespace and edge computing

- The GPL v3 model behind P4NR, public three-tier pricing, and funding node-opcua

- Node-RED next to n8n, and why versions 1 and 2 did not belong in production

- BACnet, Modbus TLS, and the security requests coming from industry

- Why digitisation keeps growing while efficiency does not

- AI in Node-RED development: giving back the 80% that was always boilerplate

Phil Seboa and Ed Fuentes sit down with David Ariens (Analytics For Industry / AVEVA) and Willem van Lammeren (Syensqo) to explore why IT/OT convergence fails — and what organisations actually get right when convergence works.

They discuss the cultural and technical silos that keep IT and OT teams divided, common misconceptions on both sides, and the practical changes that make integration stick in industrial environments.

• Breaking silos without burning bridges

• What good IT/OT integration looks like in the field

• Making OT data usable for IT and business intelligence

What changes when the assets you operate stop being centralised and predictable, and start being distributed, intermittent and weather-dependent? The old operations playbook breaks — and most digital programmes are still designed for the old one.

Dr Hema Wadhwa, Associate, Data & Analytics | Asset Management and Performance at Aurecon, joins Phil Seboa and Ed Fuentes to talk about building digital asset intelligence for the energy transition. Hema's career is a live map of that transition: she started as a Floating Systems Engineer in global oil and gas, moved through subsea engineering and power generation operations, and now leads digital strategy and analytics for mixed energy asset fleets.

Key topics in this episode:

- The unplanned career arc — floating production systems and subsea engineering into renewable operations

- "Are you here to take my job?" — what digital transformation actually feels like from inside the control room

- Why the solution providers have to evolve, not the operators

- One gas turbine versus a hundred wind turbines: why renewable fleets break the old operations model

- No standard across vendor SCADA screens and UIs, and what that inconsistency costs

- Why there is no AI magic without the data groundwork first — and why selling it that way isn't ethical

- Cognitive load: lean frontline teams, PDF report fatigue, and tools that land as a burden

- OT/IT convergence and the cybersecurity questions that come with opening it up

- OEM warranties and whether asset owners really have access to their own asset data

- Recording data when it changes, not on a fixed scan rate

- One source of truth, different views per role — data presented so it guides a decision

- Predicting failures months ahead: cranes, spares, and turning downtime into planned work

- BESS as a trading platform, not just another renewable asset

- Why the real cost driver is people, and why it only stacks up if it scales across assets

Every IIoT project starts the same way: you need data out of a PLC. The standard answer is OPC-UA — but what if that protocol is overloading your PLCs, eating bandwidth, and costing you thousands in upsized hardware?

In this episode, Christofer Dutz — creator of Apache PLC4X and CEO of ToddySoft GmbH — joins Phil Seboa and Ed Fuentes to explain why speaking the native tongue of your PLCs is faster, cheaper, and more efficient than wrapping everything in OPC-UA. Chris shares how PLC4X pulled 2,600 data points every 200 milliseconds at just 2–3% CPU overhead — compared to OPC-UA choking at 200 data points every two seconds on the same hardware.

The conversation covers the origin of PLC4X (a "JDBC for industrial automation"), the not-invented-here syndrome that created today's protocol mess, why open-source adoption in OT is still painfully slow, the role of Apache IoTDB as a time-series storage engine handling 1.5 billion insertions per second, and Chris's new commercial venture ToddySoft — bringing production-grade Rust-based drivers to platforms like Inductive Automation's Ignition.

Whether you're an automation engineer drowning in protocol adapters or an IT architect trying to bridge the OT gap, this episode is packed with practical insight from someone who has spent a decade making PLCs talk.

In the final part of our FlowFuse mini-series on Unplugged: An IIoT Podcast, Phil Seboa and Ed Fuentes close out with Kristopher Sandoval of FlowFuse on what happens once you can build fast: how do you scale, govern and standardise industrial applications across plants, lines and teams?

Kristopher explains why Expert doesn't replace developers — it removes repetitive setup so engineers can focus on operational problems, business logic, architecture and deployment strategy. We cover scaling via FlowFuse pipelines (build once, roll out to hundreds of devices), granular RBAC that persists across instances and sites, air-gapping and data sovereignty for regulated environments, and the bring-your-own-key/model future. The throughline: without FlowFuse's governance, versioning and standardisation, AI-generated apps just become technical debt.

• - 1:00 — Expert removes repetitive setup; engineers focus on operational problems

• - 5:00 — Augmenting vs replacing developers

• - 9:00 — Enterprise governance: self-hosted, BYOK, guardrails

• - 12:00 — Scaling across teams and sites with FlowFuse

In Part 2 of our FlowFuse mini-series on Unplugged: An IIoT Podcast, Phil Seboa and Ed Fuentes get practical with Kristopher Sandoval from FlowFuse. We move from “what is the application gap?” to what it looks like to close it on the shop floor.

Kristopher walks through real operational use cases—OEE dashboards, shift handover workflows, quality validation, and asset monitoring—starting with the operational problem and then showing the working application. We also dig into the technical mechanics: how FlowFuse Expert turns plain-language requirements into Node-RED nodes and flows, updates to the immersive editor in FlowFuse 2.30, and the governance layer (snapshot comparisons, change review, and deployment management) that helps teams keep changes production-ready.

• OEE: “Build me an OEE dashboard for three production lines with downtime tracking and shift comparison.”
• Shift handover: “Create a shift handover workflow where operators log production issues, actions taken, and outstanding risks.”
• Quality validation: “Create a workflow that validates production data and alerts operators when thresholds are exceeded.”
• Asset monitoring: “Create a dashboard showing machine status, downtime, and maintenance alerts.”

• 0:00 — Welcome back: real operational use cases
• 1:00 — Shift handover, quality validation, asset monitoring, Modbus-to-UNS
• 5:00 — From operational problem to working application
• 9:00 — Technical mechanics: how Expert translates needs into flows
• 13:00 — Immersive editor improvements in 2.30
• 16:00 — Governance: snapshot comparisons, change review, deployment
