S14,F20 Generic Service Acknowledge (GSA) M,H<-E
Description
The equipment acknowledges requested service or reports any error(s). If the service is accepted and completed at once, (i.e.
SVCACK = 0) then, the required parameters for the response are listed within this message. If the service is accepted but the
performance of the service takes a relatively longer time due to some physical reason, (i.e. SVCACK = 4) then, the service
response will be sent with the required parameters when the service is completed (see S14,F21/F22). The determination as to
whether a delayed response is acceptable is dependent upon the implementation. LINKID is set to a non-zero value if and only i
f
additional completion reports will be sent. The data items are mapped to the service response parameter list of the applied object
service. Parameters that apply to the list are described in the standard that defines the application of the service.

Exception
If p = 0, no errors were detected. If n = 0 parameters are returned. SVCACK is specified twice in the above structure for
backward compatibility with the previous structure of this message, and for consistency with other stream 14 reply messages.
The values of both SVCACK data items in this structure must be equal. The above message structure (L,4) is the preferred
structure for this message and must be used for new implementations. The following message structure (L,3) is included for
compatibility with previous implementations and must not be used for new implementations.

S14,F21 Generic Service Completion Information (GSCI) M,H<-E,reply
Description
The equipment notifies the original service requestor when requested service on an object is completed, either successfully or
unsuccessfully. The equipment may send required information using reply parameters. If the service was accepted and
completed at once, the information was carried with the acknowledge message, that is secondary message of requesting one, and
this message is not provided.
OPID contains the value of OPID in the initial request, i.e. S14F19. LINKID is set to a non-zero value if and only if additional
completion reports with the same OPID will be sent. If multi-block, it shall be preceded by the S14F23/F24 Multi-Block
Inquire/Grant transaction.

Description
This message is used to request to list the services of specified types of owned objects. This is an operation performed on an
object type rather than on object instances. Wild characters “?” and “*” may be used as a filter for object types. Equipment is
not required to support wild characters.
