LoRaWAN to PLC and SCADA
Connect LoRaWAN sensors to your PLC and SCADA system
Wireless sensors deliver data your control system can use. Sensor-Online decodes it and delivers it over Modbus TCP or OPC UA, with no coding and no new cabling.
500+ customers · 100,000+ active sensors · Trusted by Akademiska Hus, Vattenfall, LKAB and HSB
How it works
From sensor to control system in four steps.
Wireless sensors
LoRaWAN sensors send readings through your gateways.
Decode
Ready-made decoders turn raw payloads into named values.
Transform
Sensor-Online delivers the values over the protocol your system speaks.
Control system
Your PLC or SCADA reads the values and can write setpoints back.
What you can do
Protocol transformation lets data flow between systems that normally do not talk to each other.
Modbus TCP
Expose sensor values as Modbus registers that your PLC or SCADA can poll.
OPC UA
Publish sensor readings as OPC UA nodes for SCADA and industrial IT.
Read and write
Bidirectional communication: read process values and write setpoints or commands back.
Any protocol to any protocol
Receive on one protocol and deliver on another, for example a Modbus value over MQTT or a KNX event as a REST call.
No coding
Pick your sensor from the decoder library. No payload programming is needed.
Stays on your network
Run it on-premise behind your firewall, so process data stays inside your own network.
Platform or BridgeX?
Two ways to bring LoRaWAN into your control system.
| Sensor-Online platform | BridgeX converter | |
|---|---|---|
| What it is | A full IoT platform with protocol transformation | A converter device from LoRaWAN to Modbus TCP |
| Best for | Dashboards, alarms, reports and control-system integration together | A fast, standalone link from LoRaWAN sensors to a PLC or SCADA |
| Where it runs | SaaS or on-premise | Added to your local network, no servers needed |
| Setup | Provision devices in the platform | Add a gateway, pick sensors from the library and set the Modbus registers |
Need only the converter?
BridgeX is a ready-made device for a simple, fast link.
BridgeX converts LoRaWAN sensors to Modbus TCP, with an integrated LoRaWAN server and ready-made decoders. It is added to your local network and needs no extra servers.

Can I connect LoRaWAN sensors to a PLC?
Yes. Sensor-Online decodes the LoRaWAN data and delivers it to your PLC over Modbus TCP or OPC UA.
Do I need to write code?
No. Decoders for popular sensors are ready-made, and you can add your own if a sensor is missing.
Can the PLC write data back?
Yes. Modbus TCP and OPC UA support two-way communication, so setpoints and commands can be written back.
Which PLC and SCADA systems work?
Any system that speaks Modbus TCP or OPC UA. BridgeX has been verified against popular PLC and SCADA brands.
Does it need the cloud?
No. Run Sensor-Online or BridgeX on your own network, behind your firewall.
