When a device receives an ASDU with an unknown COT or CA or IOA value what type of Information Object should be included in the response?
I know that the response COT could have one of these values :
but what about the information objects? is it supposed to echo back the received Information Objects it received ?
I know that the response COT could have one of these values :
COT=44 COT=45 COT=46 | unknown type identification unknown cause of transmission unknown common address of ASDU |
