This is for clearing the configuration file loaded via _ECAT_Autoconfig_Open_File. It is mainly
used when a wrong file has been opened or the changes are not compatible with the previous
settings.
Note: This API can only be executed after the EtherCAT Master has been started
( “_ECAT_Master_Open” in section 6.1) and before EtherCAT communication is initialized
( “_ECAT_Master_Initial” in section 6.2).

if (Cardnum>0)
{
Status = _ECAT_Master_Get_CardSeq (0, &CardNo);
Status = _EACT_Autoconfig_Clear_ConfigFile (CardNo);
Status = _ECAT_Master_Initial(CardNo);
