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.
