Important Points:
● The SWP provides flow control-based reliable communication between the sending and receiving
software tasks.
● A sending task enqueues messages into the SWP queue3 for a receiving task and waits for an
acknowledgement.
● If no response is received within a defined period of time, the SWP timeout mechanism resubmits the
message at the head of the FIFO queue.
● After retrying a defined number of times, the SWP-2-NOMORETIMEOUT timeout message is
generated.
● In the S-Series example, a retry (Retries) value of zero indicates that the SWP mechanism reached
the maximum number of retransmissions without an acknowledgement.
