SMG-5521 – RS422/RS485 Modbus Gateway to Sollae Cloud

SMG-5521 connects Modbus RTU/ASCII devices over RS422/RS485 to Sollae Cloud through Ethernet. From the Sollae Cloud web interface you can retrieve data, control devices, and build dashboards with widgets and graphs. Use Event-Action triggers and email notifications to automate responses and alerts—without maintaining your own cloud stack.

Key features of the SMG-5521

  • • Connect RS422/RS485 Modbus RTU/ASCII devices to Sollae Cloud for remote data retrieval and control.
  • • Cloud dashboards with widgets/graphs and customizable UI via Sollae Studio.
  • • MQTT over TLS for encrypted cloud transport; supports secure device authentication.
  • • Event-Action triggers and email notifications for automation and alerting.
  • • Data storage on Sollae Cloud (up to 30 days) for trending and troubleshooting.

RS422/RS485 interface for industrial networks

SMG-5521 uses a terminal block interface for RS422/RS485 wiring and is designed for stable operation in industrial environments. This makes it a strong fit for multi-drop networks and longer serial runs commonly found in field devices and sensors.

  • • Ideal for meters, building automation, process sensors and distributed Modbus networks.
  • • Configure and monitor devices with spFinder (network/USB).

Dashboards, widgets & Event-Action logic

Visualize values through cloud widgets and build dashboards for operators and maintenance teams. Use Event-Action rules to trigger automation and send email notifications when thresholds are exceeded or states change.

  • • Multi-user access through the cloud for team operations and integrators.
  • • Stored history (up to 30 days) supports analysis and reporting.
