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

BACnet

BACnet (BACnet/IP, MS/TP) is the standard for building management systems and HVAC supervision.

BACnet driver →

Example deployment

Typical scenario Beckhoff plant in a BACnet BMS A Beckhoff TwinCAT PLC (CX series) runs a technical plant — heating, ventilation, pumps — while the site is supervised over BACnet/IP. The WBox reads the PLC's ADS variables and exposes them as native BACnet objects, so the BMS trends and commands the Beckhoff plant without a custom OPC server or extra licence. Technical documentation →

How the WBox bridges ADS and BACnet

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

Capacity & limits

  • BACnet — BACnet/IP scales to large object counts; BACnet MS/TP carries up to 127 master nodes per segment.

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 BACnet?

ADS is the Beckhoff TwinCAT PLC protocol and BACnet is the building-management (BMS) protocol. A single WBox gateway runs the ADS and BACnet drivers, speaks both protocols at once and maps the data points between them — no PC, no middleware, no cloud dependency.

Is the ADS ⇄ BACnet bridge bidirectional?

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

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

No. The ADS and BACnet 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 BACnet driver licences. The online configurator recommends the right model from your interfaces and point count.
