This blog is written for automation and controls engineers who work (or want to work) at the intersection of shopfloor and software. Posts are grouped by focus:

PLC Communication Patterns — S7, OPC UA, PROFINET, and how to get data out of PLCs reliably.

SCADA/MES Integration — WinCC, HMIs, alarm management, RBAC, and connecting control systems to MES/ERP.

IIoT & Data Pipelines — Node-RED, MQTT, SQL, edge gateways, and turning industrial signals into usable data products.

New posts are added under these categories. If you’re not sure where to begin, start with the IIoT & Data Pipelines articles — they lay the groundwork for the rest.
