10.13 Stream 9 System Errors — This stream provides a method of informing the host that a message block has
been received which cannot be handled or that a timeout on a transaction (receive) timer has occurred. The
messages indicate either a Message Fault or a Communications Fault has occurred but do not indicate a
Communications Failure has occurred.
10.13.1 Communications Failure — A Communications Failure occurs in a SECS-I environment when, and only
when, the RTY limit is exceeded.
NOTE 10: In the event of a Communications Failure, no Stream 9 message is sent.
10.13.2 Communications Fault — A Communications Fault occurs when the equipment does not receive an
expected message (when a transaction timer or a conversation timer has expired).
10.13.3 Message Fault — A Message Fault occurs when the equipment receives a message which it cannot process
because of a fault that arises from the content, context, or length of the message.
