IEC 61850-7-410 Edition 2:
Communication networks and systems for power utility automation –
Part 7-410: Basic communication structure – Hydroelectric power plants –
Communication for monitoring and control
has been published for final ballot until 2012-10-05.
Changes in Edition 2 :
- Generic logical nodes in IEC 61850-7-410 Edition 1 that are not specific to hydropower plants have been moved to IEC 61850-7-4 Edition 2.
- The definitions of logical nodes have been cleaned up.
- Most of the modeling examples and background information has been moved to IEC/TR 61850-7-510 Edition 1 (see example below).
- New general-purpose logical nodes that are not included in IEC 61850-7-4 Edition 2, have been defined.
IEC 61850-7-410 Edition 2 defines 46 Logical Node classes and several hundred data objects:
| LN Class | Description |
| ACTM | Control mode selection. |
| AJCL | Joint control function, to balance total power from different sources. |

I'm curious (not being involved in any of the standards, I don't know how these things are determined), how are the following not considered to be generic LNs?
FSCH Scheduler. This LN represents a task scheduler
FHBT Heart beat function of a controlling device
FXPS Functional priority status
I can imagine such functions to be required in any number of mechanical/control processes, or even within a substation they could have their place. (GOOSE heartbeat function? Yes please.)
And I expect a dam can leak at any number of places, no doubt, but why would they decide on making 2 LNs? Can't the different points not share a common LN and identify specifics through prefixes? I thought that was the convention.
HLKG Leakage supervision.
HDLS Dam leakage supervision.
Unless of course there is a major functional difference. I never built a dam.
What's your opinion on this?
Great blog by the way, best thing I found that keeps me up to date.
