This is like you have seen only getting the data.
The comment is part of the metadata. So you have to read them:
https://127.0.0.1:8443/automation/api/v2/nodes/plc/app/Application/sym/GVL_Test/bTest?type=metadata
The answer will be in my case:
{
"type": "object",
"value": {
"nodeClass": "Variable",
"operations": {
"read": true,
"write": true,
"create": false,
"delete": false,
"browse": true
},
"description": "This is a test boolean",
"descriptionUrl": "",
"displayName": "",
"displayFormat": "Auto",
"unit": "",
"references": []
}
}
