OPC xml client ItemName/ItemPath

hi, i'm trying to use opcxml supflow (opcxml subflow (flow) - Node-RED) and have some problems to read the variables of a SIMOTION D445_2 (Siemens). With an external Client there are no Problems to get the Values. But specialy this subflow I don't know how the syntax is (ItemName/ItemPath), where do I put in strings? does someone worked with it and can help me out?
