A packaging machine stops, every system is connected, and still nobody can say which customer shipment is at risk. This episode is for manufacturing IT/OT architects and data teams who have invested in connectivity but still answer key questions with phone…

When a bottleneck machine stops, ERP, MES and IoT data can all be correct and still not tell the factory what to do next. This episode is for manufacturing IT, OT and data architects who need to connect existing systems without a replacement program. You will…

A factory can collect mountains of data and still struggle to answer what a single machine stop really affects. This episode is for manufacturing, IT/OT and data architects who need ERP, MES, maintenance and quality data to share one meaning. Learn how an…

Factory AI can read ERP, MES and historian data but still does not know how a product, process and resource came together at one moment. This episode shows manufacturing data architects and plant engineers how a product-process-resource knowledge graph adds…

UNTANGLING THE PLANT FLOOR: MQTT vs OPC UA & THE TRUTH ABOUT DISCONNECTED MANUFACTURING DATAWhy are modern factories still running on manual exports and guesswork despite having ERP, MES, and Azure systems in place? This episode cuts through the technology…

Machine data can reach the cloud faster than ever, yet a red machine status still does not tell production which order is at risk. This episode follows one OPC UA signal through the edge, MQTT and Azure IoT into Microsoft Fabric for manufacturing IT, OT and…
No. OPC UA and MQTT move signals, but the planner's question needs meaning from several systems. A packaging machine stop can reach the dashboard in milliseconds, yet knowing which customer shipment is at risk requires MES data, ERP records and more. · From the episode: Connectivity Is Not Integration — Why Your…
The episode says it is not a battle. MQTT routes messages and OPC UA provides machine data with structure and context. · From the episode: MQTT and OPC UA in Microsoft Manufacturing
Start with the production problem first, then decide what each protocol needs to do. The episode rejects the idea of a winner-takes-all battle between MQTT and OPC UA, because the real issue is the lack of trust in the data, not the choice of protocol. · From the episode: MQTT and OPC UA in Microsoft Manufacturing
An OPC UA server exposes a tag, an edge layer collects it, MQTT can distribute it, and it crosses securely into Azure and Fabric. · From the episode: How Machine Data Reaches Microsoft Fabric …
A red machine status does not say which order is at risk, what else can run, or who needs to act. A dashboard shows the signal, but a decision needs production context, which is why the episode follows one machine signal from OPC UA all the way to Fabric. · From the episode: How Machine Data Reaches Microsoft Fabric …
