Specifies the first word of the received message (D to D+267 max.).
15
D
Contains the number of bytes of received service data from
words D+1 on. Does not include the 2 bytes in word D itself.
Includes only the number of bytes of Service Data starting at
D+1. (If the first or last word contains just one byte of data, the
empty byte in that word is not counted.)
15
D+1
to
D+267
Contains the response's service data (data
following the service code). The byte-order of
this data is specified in bits 12 to 15 of C+1.
Can contain up to 534 bytes (267 words) of
data.
C: First control word
Specifies the first of four control words (C to C+3).
15
C
Set the maximum number of words of data in the received data beginning at D.
The allowed setting range is 0 to 010C hex (268 words).
If the number of words of received data exceeds the value set here, a FINS
error will occur (response too long, code 11 0B) and no data at all will be stored
(in the area starting at D+3).
If the number of words of received data is less than the value set here, the
remaining words (in the area starting at D+3) will be left unchanged.
