Communication & SCADA Integration
Interlingo

SCADA integration is critical for visibility and automation. Communication issues are among the most reported problems.

Connectivity Issues

Connectivity failures may prevent data exchange between SmartGrid™ controllers and SCADA servers.

Checklist:

  • Verify each PCU has a unique IP address.

  • Confirm required ports (502 for Modbus/TCP, 102 for IEC 61850) are open.

  • Check physical cabling and switch link LEDs.

  • Ensure SCADA drivers match firmware versions.

Code

Description

Data Accuracy Problems

If SCADA displays incorrect or unstable values:

  • Verify sensor calibration.

  • Confirm system clock sync to NTP server.

  • Review network latency.

Accurate timestamps are mandatory for ISO compliance. Always re-verify time sync after firmware updates or system restarts.
