Hello I have a Interface Method defined with following inputs. VAR_INPUT //receive buffer pbyRxBuffer : POINTER TO BYTE; //size of the receive buffer udiRxBufferSize : UDINT; END_VAR For eg: If i get udiRxBufferSize = 10, then i copy 10 bytes through pointers Now I am relying on udiRxBufferSize for the actual size of buffer. but what if i get a wrong input from user?? He says 10 bytes, but doesnt actually provide the required size. Can i somehow check the size of actual variable which is provided...

No, it is not deleted. But why do you require a struct that has a pointer to struct? Couldn't you just embed stSub in stMain as a member?
