State: modelled. Tested on hand-written files and on each public SCL file against itself and after Rename IED; no real pair of releases of a station is public, so none has been compared.
Compare
- Run Compare IEC 61850 Files.
- Pick the earlier file, then the later file.
- A tab opens for the pair. It lists the differences by meaning, grouped by part of the station, each as a sentence, for example:
IED P1 / S1 / LD0 / LLN0 / Data set Trips: Data set member LD0/XCBR1.Pos[ST] was removed- Click a row to open the file where the thing is.
The tab follows both files on disk: save either file and the list updates.
What is compared
| Part | What is compared |
|---|---|
| IEDs | IEDs, access points, logical devices and logical nodes, and their attributes |
| Data sets | Data sets and their attributes; members added, removed or reordered |
| Control blocks | GOOSE, Sampled Values and report control blocks and their attributes, such as confRev |
| Inputs | Inputs added or removed |
| Communication | Subnetworks, connected access points and their addresses |
| Substation | Voltage levels, bays, equipment and their logical node bindings |
| Data type templates | Logical node, data object, data attribute and enumeration types, and their members |
Each difference reads as added, removed, changed order, or changed from one value to another.
The same station written differently (CRLF instead of LF, spaces instead of tabs, without a comment, IEDs in another order) has no differences. Vendor data in Private elements is not compared. Relay setting values are compared by the Relay settings editor, not here.
Try it: compare a station with a later revision in which the APPID of P1 gcb01 went from 0001 to 0002, the member XCBR1.Pos was removed from data set Trips, and confRev of gcb01 went from 1 to 2. The tab lists exactly those three changes.
The same comparison writes the "What" of Record Revision and the change list of Update IED from IID.
Limits
- The list cannot be exported.
- The description of a logical node is not among the differences listed.
Not verified
- A real pair of releases of a station.
- Which differences a reviewer needs that are not in the list.
