It works:

    //JSON
    // JSON data container
    jsonDataFactory : JSON.JSONDataFactory; // Factory to create a JSONData function block. 
    pJSONData : POINTER TO JSON.JSONData := jsonDataFactory.Create(); // Result of Create is a pointer to JSONData

    // Reader
    JSONByteArrayReader_0: JSON.JSONByteArrayReader;    
    xRead : BOOL;
    xFindValue : BOOL;
    exampleData : WSTRING(1024) := "{$"dev$": $"HOUSE-RR$", $"id$": 66,$"com$": $"OPEN DOOR$",$"val$":9,$"uid$": $"6655334455$"}";
    wsKey : WSTRING := "id";
    FindFirstValueByKey_0: JSON.FindFirstValueByKey;
    wsValue: WSTRING(JSON.GParams.g_diMaxStringSize);

JSONByteArrayReader_0(xExecute:=xRead, pwData := ADR(exampleData), jsonData:= pJSONData^);

FindFirstValueByKey_0(xExecute:=xFindValue, wsKey:=wsKey, diStartIndex:=0, jsonData:=pJSONData^);
JSON.JSONElementToString(wsResult:=wsValue, element:=FindFirstValueByKey_0.jsonElement);

I got result = "66" .

Thanks for help.

json_p2: you used a STRING when you needed a WSTRING.
json_p1: 'single quotes' is a STRING but you need "double quotes" for a wstring. to have a wstring literal with double quotes inside it, you need to use "double quotes with $"dollar sign double quote$" "
