DNP3 for utility interfaces




OPC UA/MQTT for historians and cloud analytics
Maintain protocol mapping matrices covering signal lists, register maps and IEC 61850 data models .
Coordinate with inverter, SCADA, RTU, relay and tracker OEMs for communication integration.

3. FAT/SAT & Commissioning
Validate ICDs, communication configurations and test cases during FAT/SAT.
Troubleshoot communication issues including:
Stale SCADA tags
Register mismatches
Packet loss
Communication failures
Time synchronization drift
Use tools such as Wireshark, IEDScout and Modbus Poll for diagnostics.

4. Industrial Network Hardware
Commission and maintain:
Managed industrial Ethernet switches
Media converters
Fiber patch panels
RS-485 communication networks
SCB/SMB-level communication infrastructure
Ensure proper grounding, shielding and surge protection for outdoor communication cabling.

5. Time Synchronization
Implement and maintain time synchronization using:
NTP
SNTP
PTP / IEEE 1588
IRIG-B
Ensure accurate time synchronization for protection, metering and SCADA systems.

6. Network Monitoring & Troubleshooting
Monitor network health using SNMP-based tools such as PRTG, Zabbix or SolarWinds, along with SCADA diagnostics.
Respond to network alarms and communication faults within defined SLAs.
Lead root-cause analysis for communication outages affecting:
Solar generation




Plant dispatch
Grid telemetry
Commercial metering
Maintain critical network spares to support plant availability.

7. Documentation & O&M; Support
Maintain updated as-built network diagrams, cable schedules and port-mapping records .
Support O&M;, electrical and SCADA teams during:
Shutdowns
Network upgrades
Device replacements
Firmware upgrades
Protocol changes
Grid-code and cybersecurity audits
