LoRaWAN to PLC and SCADA<\/p>\n

Connect LoRaWAN sensors to your PLC and SCADA system<\/h1>\n

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.<\/p>\n

How it works<\/h2>

From sensor to control system in four steps.<\/p>

Wireless sensors<\/h3>

LoRaWAN sensors send readings through your gateways.<\/p><\/div>

Decode<\/h3>

Ready-made decoders turn raw payloads into named values.<\/p><\/div>

Transform<\/h3>

Sensor-Online delivers the values over the protocol your system speaks.<\/p><\/div>

Control system<\/h3>

Your PLC or SCADA reads the values and can write setpoints back.<\/p><\/div><\/div><\/section>\n

What you can do<\/h2>

Protocol transformation lets data flow between systems that normally do not talk to each other.<\/p>

Modbus TCP<\/h3>

Expose sensor values as Modbus registers that your PLC or SCADA can poll.<\/p><\/div>

OPC UA<\/h3>

Publish sensor readings as OPC UA nodes for SCADA and industrial IT.<\/p><\/div>

Read and write<\/h3>

Bidirectional communication: read process values and write setpoints or commands back.<\/p><\/div>

Any protocol to any protocol<\/h3>

Receive on one protocol and deliver on another, for example a Modbus value over MQTT or a KNX event as a REST call.<\/p><\/div>

No coding<\/h3>

Pick your sensor from the decoder library. No payload programming is needed.<\/p><\/div>

Stays on your network<\/h3>

Run it on-premise behind your firewall, so process data stays inside your own network.<\/p><\/div><\/div><\/section>\n

Need only the converter?<\/h2>

BridgeX is a ready-made device for a simple, fast link.<\/p>

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.<\/p>Explore BridgeX \u2192<\/a><\/section>\n

Frequently asked questions<\/h2>
Can I connect LoRaWAN sensors to a PLC?<\/summary>

Yes. Sensor-Online decodes the LoRaWAN data and delivers it to your PLC over Modbus TCP or OPC UA.<\/p><\/details>

Do I need to write code?<\/summary>

No. Decoders for popular sensors are ready-made, and you can add your own if a sensor is missing.<\/p><\/details>

Can the PLC write data back?<\/summary>

Yes. Modbus TCP and OPC UA support two-way communication, so setpoints and commands can be written back.<\/p><\/details>

Which PLC and SCADA systems work?<\/summary>

Any system that speaks Modbus TCP or OPC UA. BridgeX has been verified against popular PLC and SCADA brands.<\/p><\/details>

Does it need the cloud?<\/summary>

No. Run Sensor-Online or BridgeX on your own network, behind your firewall.<\/p><\/details><\/div><\/section>\n
