61850位串的位序

PACKED LIST

A PACKED LIST type shall be mapped to a variable length MMS Bit-string. The minimum size

of the bit-string shall be determined by the number of bits required to encode the members of

the PACKED LIST. The order of the bits, in the bit-string, shall be that the first member of the

PACKED LIST shall be mapped to Bit(0). The other members shall be mapped in consecutive

bits in the order specified by IEC 61850-7-2 and IEC 61850-7-3.

Bitstrings shall support at least the number of bits required to represent the maximum

enumerated value defined. Bits that are returned in excess of that number of bits may be

ignored.

Bit 0 shall be the leftmost (most significant) bit of the first octet. Bit 7 shall be the rightmost

(least significant) bit of the first octet. Bit 8 shall be the leftmost (most significant) bit of the

second octet. Bit 15 shall be the rightmost (least significant) bit of the second octet. This shall

be continued in that way in further octets.
