EtherCAT Master Configuration EtherCAT Programming Guide

5.6 _ECAT_Autoconfig_Open_File

Syntax
U16 PASCAL _ECAT_Autoconfig_Open_File (U16 CardNo, I8 *FilePath)

Purpose
This is for reading and applying the configuration file of communication topology and DC data.
EtherCAT Master will refer to the saved communication topology and DC data during connection.
If the actual communication structure does not match the DC data, EtherCAT Master will return
an error code. With this API, you can avoid EtherCAT Master from issuing the wrong command
when the communication topology is changed accidently.
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).

Parameter
Name Data type Property Description
CardNo U16 Number Card No.
FilePath I8* String The directory of the configuration file

Example
U16 Status;
U16 CardNo=0;
I8 FilePath[255];
U16 Cardnum=0;
Status = _ECAT_Master_Open (&Cardnum);
if (Cardnum>0)
{
Status = _ECAT_Master_Get_CardSeq (0, &CardNo);
strcpy(FilePath, "C:\\EtherCAT_Information.dat");
Status = _ECAT_Autoconfig_Open_File (CardNo, FilePath);
Status = _ECAT_Master_Initial(CardNo);
}
