Hi,[~cdutz], Now I use the opm of plc4j. I meet chanllage as follow, could
you give me some suggest?
{color:#ff0000}how to put plc items into a list?{color}
{color:#ff0000}how to get a result calculate base on several plc items?{color}

private List<Float> myList;
public List<Float> getMyList()
{ myList= new ArrayList<>(); myList.add(weightLadleA);
myList.add(weightLadleB); return myList; }
