LoRa Modbus – LoRaWAN to Modbus TCP converters for BMS and SCADA
LoRaWAN to Modbus TCP converters – LoRa Modbus for automation and BMS
LoRa Modbus solutions (LoRaWAN ↔ Modbus TCP) enable wireless transfer of data from distributed sites to supervisory systems based on Modbus TCP. In practice, this means remote reading and control of devices that in your automation are seen as a Modbus TCP Master or a Modbus TCP Slave—without running costly cable routes over long distances.
The LoRaWAN to Modbus TCP Converters category is selected wherever range, transmission stability and fast commissioning matter: infrastructure monitoring, utilities and energy, building installations, industrial facilities, and locations where Ethernet is available only at a central point, while measurements must be collected from many distributed sites.
- Modbus TCP in the supervisory system – easy integration into BMS/SCADA and PLC via RJ45.
- Long-range LoRaWAN connectivity – ideal for distributed sites and challenging terrain.
- Master and Slave variants – selection to match the automation architecture and data collection method.
- 868/915 MHz frequency variants – matching the radio plan and region.
How LoRaWAN ↔ Modbus TCP conversion works
A LoRaWAN to Modbus TCP converter acts as a bridge between long-range connectivity and standard Ethernet-based automation. On the wired network side, the device provides Modbus TCP communication via RJ45, and on the radio side it exchanges data within a LoRaWAN network. This way, in the supervisory system (BMS/SCADA/PLC) you keep convenient Modbus TCP integration, while the transmission to remote points is performed wirelessly.
This approach is particularly effective in retrofit projects where running cabling is difficult or not cost-effective. In practice, the integrator gets a stable data channel for reading measurements and statuses and for executing control tasks using standard Modbus TCP mechanisms.
Modbus TCP Master or Modbus TCP Slave – selecting the right option for the supervisory system
In this category you will find devices in Modbus TCP Master and Modbus TCP Slave versions. Choosing the right variant matters, because it determines how the device operates on the Modbus TCP side:
- Modbus TCP Master – a typical choice when the device must actively acquire data and perform Modbus TCP requests within the project architecture.
- Modbus TCP Slave – the right choice when the supervisory system is expected to poll the device as a Modbus TCP server and the data must be available as registers.
- Selecting 868/915 MHz frequency – chosen depending on the radio plan, region, and project requirements.

Models available in this category (LoRaWAN to Modbus TCP)
Below we have collected models from the series visible in this category. They differ by the role on the Modbus TCP side (Master/Slave) and by the 868 MHz or 915 MHz frequency variant. The common denominator is practical integration: LoRaWAN on the radio side, Modbus TCP on the Ethernet side, DIN-rail mounting, and an SMA antenna (according to the variant).

Typical LoRa Modbus applications
In practice, LoRa Modbus is most often used in projects where data must be collected from many distributed points, and the supervisory system runs on Modbus TCP. This makes it possible to quickly build consistent monitoring and control based on standard automation.
- Remote reading and integration of measurements in BMS/SCADA (utilities, infrastructure, distributed sites).
- Monitoring device statuses and alarms in hard-to-reach locations.
- Retrofits – adding data transmission without laying new cable routes.
- Distributed systems where Ethernet exists only at the central point, and measurement points are remote.
- Projects requiring a simple, standard Modbus TCP interface for PLC controllers and BMS systems.
FAQ – LoRa Modbus (LoRaWAN to Modbus TCP)
What is LoRa Modbus?
LoRa Modbus is an integration where data is transmitted via LoRaWAN and made available to automation as Modbus TCP (Master or Slave).
When should I choose Modbus TCP Master and when Modbus TCP Slave?
The choice depends on the project architecture: Master is used when the device must execute Modbus TCP requests, and Slave when the supervisory system should poll it as a Modbus TCP server.
868 MHz or 915 MHz – which variant should I choose?
It depends on the radio plan and the project region. This category includes 868 MHz and 915 MHz variants selected to match installation requirements.
Do the devices have RJ45 Ethernet and DIN-rail mounting?
Yes – typical variants in this series provide Modbus TCP via RJ45, DIN-rail mounting, and an SMA antenna (according to the specific model).
Do I need network infrastructure for LoRaWAN?
Depending on the project architecture, LoRaWAN may require suitable infrastructure (e.g., gateways and network layer) or integration with an existing operator network.
How do I choose the right model for my BMS/SCADA?
The most important factors are: Master/Slave selection on the Modbus TCP side, 868/915 MHz frequency variant, and required interfaces (RJ45, optionally RS232). Contact us and we will select the model for your project.
