Buyer scenario
An Edge RTU focuses on field signals, point lists and control-room protocols. An IoT gateway focuses on connectivity, payload translation and cloud handoff.
Decision table
Primary role
- Edge RTU
- Collects IO and field protocol points
- IoT gateway
- Moves data to cloud or platform
- Guidance
- Many projects use both roles in one package.
Buyer language
- Edge RTU
- SCADA, DI/DO/AI/AO, point list
- IoT gateway
- MQTT, API, cellular, device management
- Guidance
- Use the term your customer system expects.
Hardware focus
- Edge RTU
- Rugged IO and local polling
- IoT gateway
- Backhaul, protocol conversion and security
- Guidance
- Quote scope depends on where the data leaves the site.
Typical Hardware Architecture
Final system design, software integration, PLC/SCADA programming and site installation are handled by the customer or their system integrator.
