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.
