I am working on EtherCAT protocol and trying to read EtherCAT SDO parameter using CoDeSys. I did all the configuration and added suported libraries. but when I am trying to go online, CoDeSys is throwing me error :
"No source code available for this object because it is in the compiled library 'ethercatstack, 3.5.16.0'. Do you want to browse for the original library in order to display the source code?"

I am not getting what I am doing wrong and how to resolve this error. Can someone please help me in resolving this error?
Libraries that I am using : snap is attached. I am using "ETC_CO_SdoRead()" function to read SDO.

Thanks in advance for the help!!!

it looks like you're causing an exception in this library right on start.
Codesys can't tell you where because it has no source for the library.

Cause could be an invalid pointer.

You have to declare some inputs.
declaration:
SdoRead_RU01: ETC_CO_SdoRead;
wRU01: WORD;

code:
SdoRead_RU01(
xExecute:= ,
usiCom:= 1, //index of master 1: first ETC master
uiDevice:= DRIVE_400U1.PhysSlaveAddr,
wIndex:= 16#2C01,
bySubindex:= 16#00,
udiTimeOut:= 500,
pBuffer:= ADR(wRU01),
szSize:= SIZEOF(wRU01));
