Multi-sentence messages can be transmitted where a data message exceeds the available character space in a single sentence. Key fields that support the multi-sentence message feature will always be included, without exception. Required fields are: total sentence count, sentence number, and sequential message identifier fields. Sentence definitions containing only these fields can be used to create a message. The TUT clause is a good example of how to define a sentence to provide these capabilities.

The listener must be aware that a multi-sentence message can be interrupted by a higher priority message such as an alarm sentence, and therefore the original message should be discarded incomplete and await retransmission. The listener should check that multiple sentences are adjacent.

If an error occurs in any sentence of a multi-sentence message, the listener will discard the entire message and be ready to receive the message again on the next transmission.
