a b
a =
Parameter number of the requested parameter from page 2
(transmitted module 256)
b =
MID of the component from which the parameter data is requested.
Only the speci
fi
ed component should transmit the speci
fi
ed
parameter. If the speci
fi
ed component is in the MID range 0 to 127,
its response is not de

n,a,b,c/d,c,c,c,c,c,c,c
n =
Byte count of data that follows this character. This excludes
characters MID, PID 448, and n, but it includes a, b, c, or d type
characters.
a =
PID from page 2 (PIDs 256 to 510) specifying the parameter that
has been selected.
b =
The last section number (total number of sections minus ONE)
and the current section number. The upper nibble contains the last
section number (1 to 15). The lower nibble contains the current
section number and is limited to the range 0 to 15. Section numbers
are assigned in ascending order.
c = Data portion of sectioned parameters. May be 1 to 13 characters in
the
fi
rstpacket as byte d is transmitted only in the
fi
rst packet. May
be 1 to 14 characters in the middle and ending packets.
d = Total byte count of the original data. It is the same value as the byte
count of the parameter being sectioned. This character is broadcast
only in the
fi
rst packet. The value must be greater than 16 but is
limited to 224.
All information subject to change without notice.
