Send-Pacing Protocol

The SLU automatically controls the send-pacing protocol. If the pacing indicator is set on in a message from the PLU to the SLU, the SLU issues a pacing response when the application program reads the message. The message response can contain the pacing indicator or, if no response is required for the received message, the pacing response can be an isolated pacing response (IPR). The PLU can then send another pacing window of messages.
