The Automation Hub • Concepts
Automation Concepts Explained
Industrial automation runs on pairs of concepts people constantly confuse - HMI and SCADA, PLC and RTU, polling and report-by-exception. This hub settles each one in plain English: what the difference actually is, when it matters, and which you need. No vendor spin, just clear comparisons.
