Modbus RTU in 2026

Many new devices still ship with RS485.

Make these data points available to modern systems without making the installation unnecessarily complicated.

SB1000 can convert Modbus RTU to both MQTT and BACnet IP.
Configure it quickly in the built-in web interface and use the component library to deploy well-known products without thinking about Modbus addresses and point scaling.

BUS COMMUNICATION without friction

A short path to usable data.

SB1000 is made for installations where measurement values must be reliably collected from the field bus and forwarded to the systems that need them in many different ways.

  • Energy meters, water meters and HVAC units on Modbus RTU
  • Virtual COM port
  • Baud rate conversion

A growing device library

More reuse with the component library.

SB1000 has a built-in component library that supports many of the most widely used products in building automation, and more products will be added over time.

You can also add your own products if you only need certain points or have other needs.

Library metaphor for profiles and reuse
