39、namic usage by the DLMS user; S - the parameter is selected among other S-parameters as internal response of the DLMS server environment; C - the parheter is conditional upon other parameters or the environment of the DLMS user; (blank) - the parameter is never present. The “(=)“ code following one
40、of the M, U, C or S codes indicates that the parameter is semantically equivalent to the parameter in the service primitive to its immediate left in the table. (For instance, an “M(=)“ code in the indication service primitive column and an “M“ in the request service primitive column means that the p
41、arameter in the indication primitive is semantically equivalent to the one in the request primitive). Some parameters may contain subparameters. Subparameters are indicated by labelling of the parameters as M, U or C, and indenting all subparameters under the parameter. Presence of the subparameters
42、 is always dependent on he presence of the parameter that they appear under (for example, an optional parameter may have subparameters; if the parameter is not supplied, then no subparameters may be supplied). The descriptions of parameters in this specification make reference to types, in order to
43、describe the allowable values for such parameters. The types referenced are defined in ISOIIEC 8824. 3.5.2 AddressinP in DLMS The DLMS specification does not provide the means for naming and addressing of a peer DLMS user or peer DLPM. Within OS1 and within DCP, the identification and addressing of
44、peer application entities is carricd out through the use of ACSE services defined in IS0 8649. After such an association between peers has succeeded, all of the DLMS PDUs flow between these peers over the (A-I)-LAYER services. It is therefore not necessary for DLMS to carry addressing information. A
45、dditional information on naming and addressing may be found in the application layer specification. EN 61334-4-41 : 1996 3.5.3 Sentice conventions This specification uses the descriptive conventions contained in the OS1 Service Conventions (ISAEUIR 850s). nie OS1 service conventions define the inter
46、actions between the DLMS user and the DLMS provider. Infomation is passed between the DLMS user and the DLMS provider by service primitives, which may convey parameters. The following remarks apply to the use of this model: a) iSO/iECYR 8509 defines a model for the service provided by a layer of the
47、 OS1 reference model. The DLMS service does not correspond to such a layer (it describes a part of the application layer) but the model used is identical in ail other respects; b) at any instant in time, an AE has multiple service requests outstanding, each proceeding independently of the others. NO
48、TE- It should be noted that the DLMS user/DLMS provider distinction is an abstraction, and may not neassariiy correspond to a realization of DLMS in any particular system. 3.5.4 Sendinp and receivina DLMS user and DUM This specification makes use of the tenns sending and receiving DLMS users. The se
49、nding DLMS UsCr is the DLMS user that issues a request or response service primitive. The receiving DLMS user is the DLMS user that receives an indication or confirmation service primitive. NOTE - It is important to note that, in the course of completion of a confirmed DIMS service, both DLMS users will be sender and receiver at the same time. The first DLMS user sends the request and receives the oonfinnation, while the second DLMS user receives the indication and sends the response. This specification makes ust of the terms sending and receiving DLPMs.
