The NO_RES message is neither a replacement for nor redundant to MSG_DEN or WARNING. The latter must be issued immediately after processing a message. The NO_RES may only be issued after a certain period of time.

Furthermore, a NO_RES is not a replacement for a REQ_CAN or RES_REM message. Generally, REQ_CAN has to be used by the hub that sent the request, NO_RES has to be used by the hub that received the request. The exception is the SMP_REQ message. Depending on the status of the request, a NO_RES can be sent by sender or recipient of the request. Here, a NO_RES can only be used if a result is expected by the recipient (i.e. NO_RES can be sent by DC only before sending SMP_ARR and/or IDM_RES and NO_RES can be sent by TC only after receiving SMP_ARR and/or IDM_RES. Incorrectly received NO_RES and REQ_CAN messages can be rejected. Please see also TYP_REQ and SMP_REQ message flow.
