Need to connect ADS and MQTT? The Weble WBox routes ADS MQTT natively: one gateway speaks both protocols and maps data points in real time — no PC, no middleware, no cloud dependency.

The protocols

ADS

ADS is the native protocol of Beckhoff TwinCAT PLCs.

ADS driver →

MQTT

MQTT is the lightweight publish/subscribe protocol used by IoT devices and cloud brokers.

Example deployment

Typical scenario Beckhoff machine data to the cloud An OEM building a machine on Beckhoff TwinCAT wants fleet telemetry without exposing the PLC. The WBox reads ADS variables (cycle counts, temperatures, alarms, energy) and publishes them to an MQTT broker, turning each installed machine into a clean cloud feed for monitoring and predictive maintenance.

How the WBox bridges ADS and MQTT

On the WBox you enable the ADS driver and the MQTT driver, then map each point: a value read on the ADS side — the Beckhoff TwinCAT PLC protocol — is exposed on the MQTT side — the lightweight IoT publish/subscribe protocol — and vice-versa. Conversion, scaling and logic run on the gateway itself.

Capacity & limits

  • MQTT — MQTT imposes no point limit — topics scale with your broker and network.

On the WBox, a driver licence enables the whole protocol — there is no artificial per-point tier to unlock. Capacity scales with the gateway model, from the compact S103 to the E413: you are bounded by the field bus, not by your licence.

Frequently asked questions

How do I connect ADS and MQTT?

ADS is the Beckhoff TwinCAT PLC protocol and MQTT is the lightweight IoT publish/subscribe protocol. A single WBox gateway runs the ADS and MQTT drivers, speaks both protocols at once and maps the data points between them — no PC, no middleware, no cloud dependency.

Is the ADS ⇄ MQTT bridge bidirectional?

Yes. The WBox reads and writes on both sides: a value or command on the ADS side propagates to MQTT, and vice-versa.

Do I need a PC, a PLC or proprietary hardware?

No. The ADS and MQTT drivers are licence-activated on one WBox — no gateway PC, no intermediate PLC and no proprietary hardware.

Which WBox model do I need?

Any WBox with the ADS and MQTT driver licences. The online configurator recommends the right model from your interfaces and point count.
