How can I collect all data from the opc server? I open elements one by one and it's not convenient to me:

grp = addgroup(da);

itm1 = additem(grp, 'LINE.currentAn');

r = read(itm1, 'device');

currentAn=r.Value;

itm1 = additem(grp, 'LINE.currentBn');

r = read(itm1, 'device');

currentBn=r.Value;

itm1 = additem(grp, 'LINE.currentCn');

r = read(itm1, 'device');

currentCn=r.Value;

etc...
