Syntax
U16 PASCAL _ECAT_Autoconfig_Get_NodeID_Alias (U16 CardNo, U16 RealNodeID, U16
*MapNodeID)

Purpose
This is for acquiring the user-defined station alias of each node.
*Set after initialization.
Note: This API can only be executed after the EtherCAT Master has been started
( “_ECAT_Master_Open” in section 6.1). To use user-defined station alias of each node
( “_ECAT_Autoconfig_Set_NodeID_Alias” in section 5.10), you will need to apply API

U16 MapNodeID;U16 Cardnum=0;
Status = _ECAT_Master_Open (&Cardnum);
if (Cardnum>0)
{
Status = _ECAT_Master_Get_CardSeq (0, &CardNo);
Status = _ECAT_Autoconfig_Get_NodeID_Alias (CardNo, NodeID, &MapNodeID);
