Intelligent Field Device (IFD)
Real-time monitoring, energy metering and remote control of railway electrical assets — lifts, escalators, platform lighting, pumps, solar plants, high masts and DG sets — reporting to IR-NIYANTRAC, Indian Railways' CRIS-hosted cloud platform, over the oneM2M Common Service Platform.
IFD — Intelligent Field Device for IR-NIYANTRAC
Real-time monitoring, energy metering and remote control of railway electrical assets — lifts, escalators, platform lighting, pumps, solar plants, high masts and DG sets — reporting to IR-NIYANTRAC, Indian Railways' CRIS-hosted cloud platform, over the oneM2M Common Service Platform.
As per RDSO Specification IS/RDSO-PSE/1004:2026 (Rev-0)
Features
Master–Slave architecture
IFD Master aggregates IMCU Slaves over Modbus RS-485/TCP; 4G/5G to IR-NIYANTRAC with Ethernet/Wi-Fi secondary path and automatic switchover.
Class 0.5s energy metering
Four-quadrant, phase-wise voltage, current, power factor, frequency, active/reactive/apparent power, energy and THD.
Remote asset control
ON/OFF, time-based, running-hours and restricted schedules — executed locally even without connectivity, with power-failure compensation.
Store-and-forward & FOTA/POTA
Minimum 10 days of buffered data with automatic synchronisation; secure remote firmware and configuration updates.
Secure by design
Encrypted communication per CRIS Message Communication Format; hardware AES / SHA-256 / TRNG; TEC IoT security code of practice.
Built for the field
IP-65 enclosure, sunlight-readable LCD, battery backup (4 h Master / 15 min Slave); EMC per EN 50121-4.
