Protocol Translation Visualizer

Protocol Translation Visualizer

Visualize Protocol Translation Flows

Protocol Translation Lab

Choose two IoT protocols, translate a payload through a gateway pipeline, and inspect which addressing, reliability, security, and encoding semantics survive cleanly.

Try

Set Source Protocol to Modbus and Target Protocol to MQTT, then press Normalize Payload before Play Translation.

Observe

Normalize Payload turns register address and raw value into a named MQTT field with units, while risk flags mark unmapped metadata.

Explain

Translation preserves meaning only when identifiers, units, reliability intent, and command semantics have explicit cross-protocol mappings.

Technical boundaries. The mapper applies deterministic field and unit transformations between teaching message shapes. It does not connect live brokers or devices, validate full protocol syntax, preserve every vendor extension, handle partial failure, enforce authorization, or guarantee semantic equivalence.

Goal

Understand what a gateway must preserve, transform, or approximate.

Try

Use Play Translation to compare 3 paths: MQTT to HTTP, CoAP to MQTT, and Modbus to MQTT.

Watch

Use semantic risk, mapping notes, and compatibility checks together.

Reflect

Which mismatch would cause data loss, duplicate actions, or unsafe control?

Guided Investigation

1. Start with MQTT to HTTP and inspect how topic addressing becomes a request path.
2. Switch to Modbus to MQTT and notice that register meaning must be supplied externally.
3. Use the compatibility checks to decide whether the bridge needs buffering or deduplication.

Scenario Focus

Cloud ingest bridges MQTT telemetry into an HTTP API while preserving device identity and delivery intent.
