Need to connect ADS and KNX? The Weble WBox routes ADS KNX 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 →

KNX

KNX is the worldwide standard for home and building control, running over twisted-pair, IP or RF.

KNX driver →

Example deployment

Typical scenario Beckhoff plant ⇄ KNX rooms Rooms run on KNX (lighting, blinds, presence), but a Beckhoff TwinCAT PLC manages the central HVAC plant. The WBox links the two: KNX states reach the PLC as ADS variables, and PLC commands drive KNX actuators — one device instead of a hand-coded coupling. Technical documentation →

How the WBox bridges ADS and KNX

On the WBox you enable the ADS driver and the KNX driver, then map each point: a value read on the ADS side — the Beckhoff TwinCAT PLC protocol — is exposed on the KNX side — the building field bus (lighting, blinds, HVAC) — and vice-versa. Conversion, scaling and logic run on the gateway itself.

Capacity & limits

  • KNX — KNX exposes the installation's group objects; a TP line carries up to 64 bus devices, extended through lines, areas and KNXnet/IP.

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 KNX?

ADS is the Beckhoff TwinCAT PLC protocol and KNX is the building field bus (lighting, blinds, HVAC). A single WBox gateway runs the ADS and KNX drivers, speaks both protocols at once and maps the data points between them — no PC, no middleware, no cloud dependency.

Is the ADS ⇄ KNX bridge bidirectional?

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

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

No. The ADS and KNX 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 KNX driver licences. The online configurator recommends the right model from your interfaces and point count. For KNX TP, choose the WBox S485 KNX, which has the twisted-pair interface on board.
