S7,F41 Large Process Program Request(LPPR) S,H <-> E, reply
Description
This message is used to request the transfer of a process program via the Stream 13 Data set Transfer protocol. The Data Set
name, DSNAME, is the text string identifier of the process program, PPID. The Data Set is subsequently transferred as a Stream
with the following internal SECSII structured data:

S7,F42 Large Process Program Acknowledge (LPPA) S,H <-> E
Description
Acknowledge or error. A returned status of “accepted” means only that the message is understood. When the receiving entity is
the equipment, there is a separate verification transaction (For example: S7,F27/S7,F28) that indicates the completion status of
the request. When the receiving entity is the host, the completion of the request is signaled by an event report.

<ACKC7>
Exception
It is possible to use the ACKC7 code “command will be performed with completion signaled later” for this message.

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.
