Reference Guide

Timeout Timeout count
Retries Number of retransmissions
Msg Sent Number of messages sent
Ack Rcvd Number of messages acknowledged
Aval Retra Number of retries left/available
Max Retra Number of retries allowed
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 example, a retry (Retries) value of zero indicates that the SWP mechanism
reached the maximum number of retransmissions without an
acknowledgement.
