IEC 61850

IEC 61850

Standard for electrical substation automation and communication between IEDs.

Key Takeaways

  • Standard for electrical substation automation and communication between IEDs.
  • Advanced-level topic in Communication Protocols

Detailed Definition

Standard for electrical substation automation and communication between IEDs. This term is essential for understanding communication protocols in industrial automation and PLC programming.

IEC 61850 is one of the protocol or networking concepts an automation engineer encounters as soon as a plant has more than one controller talking to a shared device. Standard for electrical substation automation and communication between IEDs.

The role of IEC 61850 in a plant network depends on which layer of the protocol stack it occupies. Lower-layer concerns are about wiring and electrical reliability; higher-layer concerns are about message structure, addressing, and integration with vendor-specific tooling.

On the bench or in the field, IEC 61850 typically reveals itself through specific symptoms — timeouts, packet loss, addressing conflicts, or framing errors — that point to the specific layer at fault. Mature engineers learn the symptom-to-cause mapping for each protocol they touch.
