RS485 to IoT Gateway Migration in India: Step-by-Step Plan

Legacy RS485 assets remain common in Indian manufacturing and utility operations. Instead of replacing all equipment, teams can deploy industrial gateways to expose existing device data to modern cloud and analytics systems.

Migration checklist

• Audit device map: model, protocol, polling interval, baud rate
• Standardize tag naming and unit normalization
• Select gateway with Modbus, MQTT, and remote management support
• Set fallback, retries, and watchdog rules before production go-live

Expected outcomes

A controlled migration improves observability and cuts manual data collection effort. Plants usually see faster fault diagnosis, better SLA reporting, and a strong foundation for predictive maintenance.
