In the S-IDL and LFS states,
31、 the physical layer entity is ready to receive and process the incoming P-Sync primitives. - In the S-IDL, LFS and C-IDL states, the physical layer entity is ready to receive the incoming P-Data primitives, but they cannot be processed in the LFS state. In the SPF.W state, the physical layer appends
32、 the preamble (AAAAH) and the start subframe delimiter (54C7H) to the received P-sdu and waits for the next time slot. In the SPF.S, it sends the corresponding 42 bytes (2+2+38). The pause time is achieved by waiting for the next time slot. In the S-RPF.C and C-RPF states, the physical layer checks
33、the validity of the preamble and the start subframe delimiter. It also defines the best demodulation method for the reception (see 2.2, for more information). In the RPF.R, it receives the 38 bytes corresponding to the P-sdu. The pause time is not taken into account (wait for the next time slot). In
34、 the LFS state, the physical layer looks for the sequence preamble + start subframe delimiter (AAAA54C7H). It also determines the delta electrical phase. 3.5.5.2 3.5.5.2.1 Notation for physical primitives This subclause defines abbreviations used in the state tables for physical primitives passed wi

The following array lists the server and client physical mana
38、gement variables that are used in the S-FSK profile. These variables are available for system management purposes. In DCP, the server physical management variables are linked to DLMS objects of the management information base (MIB). Refer to IEC 61334-4-512 for more details. O BSI 17 October 2001 Pa

For further details, refer to IEC 61334-4-51 1. 3.5.5.4 State functions 3.5.5.4.1 Check () The Check () function returns an indication about the success or failure of the processing o
41、f the P-sdu transmitted in a P-Data.request primitive and the availability of the required resources. The possible returned values are: - OK: length of the P-sdu equal to 38 bytes and resources available; - LP-TU: resources temporally unavailable; - LP-NI: asked service not implemented in the local
42、physical layer; - LP-HF: hardware failure; - LP-NS: physical layer not synchronized; - LP-SE: length of the P-sdu different from 38 bytes. 3.5.5.4.2 Check-Read() The Check-Read() function returns an indication of the success or failure of the processing of the Read-Request() management primitive. Th
43、e possible returned values are the following: - OK: parameter fields successfully processed and resources available; - LP-NI: asked service not implemented in the local MAC sublayer; - LP-TU: local resources temporally unavailable; - LP-SE: syntax error in the submitted primitive; - LP-HF: hardware
44、failure. 3.5.5.4.3 Checkwrite() The Checkwrite() function returns an indication of the success or failure of the processing of the Write-Request() management primitive. The possible returned values are the following: - OK: parameter fields successfully processed and resources available; - LP-NI: ask
45、ed service not implemented in the local MAC sublayer; - LP-TU: local resources temporally unavailable; - LP-SE: syntax error in the submitted primitive; - LP-HF: hardware failure.

47、enerated by the physical layer after the sending of 42 bytes (preamble + SSD + P-sdu). 3.5.5.4.6 Is-Server() The Is-Server function returns TRUE if the physical layer shall act as a server physical layer. Otherwise, the Is-Server function returns FALSE. This function checks a management variable set
48、 by the management application. 3.5.5.4.7 Local-Status () The Local-Status function returns VALID if all that is required to ensure sending or receiving is available (for example, 50 Hz synchronization, baud rate). Otherwise, the Local-Status function returns INVALID. This function checks a manageme
49、nt variable which defines the baud rate and checks the hardware initialization. 3.5.5.4.8 Preamble-SSD() The Preamble-SSD function returns OK if the four received bytes correspond to the preamble (AAAAH) and the start subframe delimiter (54C7H). Otherwise, it returns not OK. This function generates an event after the reception of four bytes in the S-RPF.C or C-RPF.C states. 3.5.5.4.9 Read-Request() This event corresponds to a management primitive generated by the systems management application entity (SMAE: refer to IEC 61334-4-512) for submitting the reading of a server o
