Integrationsleitfaden fuer MQTT und SCADA

Introduction

Document how plant-floor data moves from field protocols into MQTT topics and SCADA consumers.

Prerequisites

• Field protocol list
• MQTT broker access
• SCADA tag mapping

Steps

1. Normalize machine data

   Map field registers to semantic tags before sending anything upstream.

2. Design the topic tree

   Include site, line and machine identifiers and separate telemetry from alarms.

3. Connect SCADA consumers

   Map critical tags first and validate timing before scaling out.

Note: Version payload schemas when multiple consumers share the same topics.

Expected Outcome

Field data reaches SCADA and cloud systems with a stable naming model.
