IoT Protocol Conversion – Connect LoRaWAN Sensors to PLC and SCADA Systems

Sensor-Online enables seamless protocol conversion between modern IoT technologies and traditional industrial automation systems. Wireless LoRaWAN sensor data can be securely integrated into existing PLC and SCADA environments without redesigning your control architecture.

This makes it possible to combine low-cost, wireless IoT sensors with established industrial systems in a flexible, scalable, and cost-efficient way.

Bridge LoRaWAN with Industrial Protocols

Sensor-Online acts as a protocol bridge between LoRaWAN and widely used industrial communication standards. Sensor data collected wirelessly can be converted and exposed as:

  • Modbus TCP/IP
  • OPC UA / OPC
  • MQTT
  • REST and other IP-based interfaces
  • Custom protocol mappings when required

This allows PLCs, SCADA systems, and industrial software to consume LoRaWAN sensor data in the same way as data from traditional wired field devices.

Use Wireless Sensors in Existing PLC and SCADA Systems

LoRaWAN sensors are wireless, battery-powered, and fast to deploy. By integrating them into PLC and SCADA systems, organizations can add new measurement points without modifying existing automation infrastructure.

  • Add sensors where cabling is impractical or too expensive
  • Extend monitoring without downtime or production impact
  • Collect data from remote, mobile, or hard-to-reach locations
  • Maintain a unified operational view in SCADA systems

Near-Zero Installation Cost Compared to Wired Sensors

Traditional wired sensors often require extensive electrical work, including cabling, conduits, I/O cards, and shutdowns. In contrast, LoRaWAN sensors can typically be installed and commissioned in minutes.

  • No cabling, trenching, or cable trays
  • No electrical installation work in most cases
  • Minimal disruption to ongoing operations
  • Significantly reduced labor and material costs

This results in a dramatically lower total installation cost compared to conventional wired sensor solutions.

Mixed-Protocol Architectures Reduce Total System Cost

Sensor-Online supports mixed-protocol architectures, where each part of the system uses the most suitable and cost-effective communication method.

Typical examples include:

  • Critical control signals handled by wired fieldbus systems
  • Monitoring and non-critical measurements handled by LoRaWAN
  • All data unified and exposed to PLC and SCADA via standard protocols

By combining wired and wireless technologies, overall system cost is reduced without compromising reliability or functionality.

A Central Integration Layer Between IT, OT, and IoT

Sensor-Online acts as a central integration layer between industrial automation (OT), enterprise IT systems, and modern IoT solutions.

  • Wireless LoRaWAN sensors for rapid deployment
  • Protocol conversion for industrial compatibility
  • Centralized data management and security
  • Future-proof architecture for system expansion

This approach allows organizations to modernize step by step while protecting existing investments in PLC and SCADA systems.

Lower Cost, Higher Flexibility, Better Coverage

By enabling protocol conversion and mixed-protocol designs, Sensor-Online makes it possible to build automation and monitoring solutions that are more flexible, scalable, and cost-efficient.

The result is an IoT-enabled control environment where wireless LoRaWAN sensors and traditional PLC/SCADA systems work together seamlessly — delivering better insights at a lower total cost.
