Parameter Name
Bytes
Format—U16
Bits 0-2 = The Buffer Index of the oldest information from the R7999.
(Incremented by the BC status message once a second.)
Bits 0-15 = A counter synchronized with R7999 messages.
0-11 These buffers store an 8-second history of status data from the
R7999. The oldest buffer is indicated by register 40160, bits 0-2. This
scheme forms a circular buffer of information. A buffer will contain all
0-11
zeros if the S7810M received bad data for the buffer time slot. See
Table 25 for interpretation of bytes 0-11.
