Using Protocol Macros Section 5-5

Depending on the response received, the user can either choose to resend the same send message (retry processing), or to perform the next process (for ex- ample, read the process value for a Temperature Controller with a different ad- dress).

Note 1. The SEND, RECEIVE, or SEND&RECEIVE commands can be used.

2.Three types of reception matrix are available for switching the processing, depending on whether the messages are send messages, receive (wait) messages, or multiple receive (wait) messages. Unlike sequences, these matrixes are managed as lists.

3.Retries are possible on for the SEND&RECEIVE command.
