1. What is this?

This plugin removes one or more IEDs from an SCL file. It is a menu plugin for OpenSCD. It uses the oscd-edit-v2 event and the doc and docVersion plugin properties.

The plugin removes the data which refers to the selected IEDs:

• The IED and AccessPoint elements.

• ConnectedAP, GSE and SMV addresses.

• Association, ClientLN and KDC elements.

• IEDName text content.

• Subscriptions and supervisions in other IEDs.

Associated LNode elements are preserved with iedName="None" by default. The dialog can delete them instead. The dialog can also delete a SubNetwork or a Communication section which the removal empties. Both section deletions are off by default and show a schema warning.

All changes from one removal are one undoable action.

See the documentation or try it online.

2. Add the plugin

Add this entry to the menu plugins of an OpenSCD distribution:

{
  "name": "Remove IEDs",
  "icon": "delete",
  "requireDoc": true,
  "src": "https://openpowershift.github.io/oscd-menu-remove-ieds/oscd-menu-remove-ieds.js"
}

The host must supply doc and a reactive docVersion. A host which supplies only the legacy editCount does not work.

To use a release, install the npm package and set src to its bundle.

3. Development

The plugin uses Node.js 22 and @omicronenergy/oscd-tooling.

$ npm install
$ npm run start

npm run lint	Run the linter.
