Start with the two protocols you need to connect.

Each gateway is designed around a clear source-to-target communication task, making product selection and commissioning straightforward.

ModbusBACnet

Modbus to BACnet

Publish meters, controllers and field values as BACnet objects for a BMS.

Modbus RTUTCP

Serial to Ethernet

Connect serial Modbus devices to Ethernet-based SCADA, HMI or controllers.

ModbusKNX

Modbus to KNX

Map HVAC, energy and control values to KNX group addresses.

BACnet MS/TPIP

BACnet Routing

Route BACnet traffic between MS/TP field networks and BACnet/IP.

Connect. Map. Convert.

A consistent commissioning workflow across the protocol gateway series.

Connect

Set serial ports, Ethernet parameters, device addresses, baud rates and protocol roles.

Example: COM1 · RS-485 · 9600 bps · Modbus Client

Map

Create a clear relationship between source registers, values or devices and target protocol objects.

Convert

The gateway continuously polls, converts and serves data to the target network in real time.

Continuous conversion: source values are processed and published as target protocol objects
Data table

Configure everything in your browser.

Set up both sides of the conversion, build point mappings, verify live values and diagnose communication without installing additional engineering software.

01

Communication Setup

Configure serial, Ethernet and protocol parameters.

02

Point Mapping

Map source addresses to target protocol objects.

03

Live Verification

Check values and status before commissioning.

04

Diagnostics

Review timeout, exception and protocol logs.

Conversion gateways and protocol routers.

Shared browser-based engineering, with protocol-specific functions for each connection task.

Convert between different protocol models.

Translate field addresses, values and data types into objects or group addresses used by the target system.

Modbus to BACnet Gateway

Connect Modbus RTU/TCP devices to BACnet/IP or BACnet MS/TP systems.

Object MappingCOVAI / BI / AV / BV

Modbus to KNX Gateway

Map Modbus registers and control values to KNX group addresses.

Group AddressDPT MappingRead / Write

Bridge network media within one protocol ecosystem.

Connect serial and Ethernet segments while preserving the protocol's native communication model.

BACnet IP–MS/TP Router

BACnet Routing

Route BACnet traffic between IP networks and MS/TP field controllers.

BBMDBDT / FDTNetwork Numbers

Modbus RTU/TCP Gateway

Modbus Routing

Bridge Modbus serial devices with Modbus TCP clients and servers.

Multi-clientRoutingPolling Control

Built for real field work.

Tools for fast verification during commissioning and easier maintenance after delivery.

Live Data

View current values, quality and update timestamps from the browser.

Communication Status

See connected devices, response state and timeout counters.

!

Protocol Logs

Review exceptions, malformed responses and connection events.

Configuration Backup

Export, restore and replicate validated project configurations.

Find the right protocol gateway.

Choose the protocols on both sides, then confirm the required interfaces, device count and data point capacity.
