S
Set the number of bytes of source data from words S+1 on. For
example, set S to 000A hex if there are 5 words of data (S+1 to
S+5). Do not include the 2 bytes in word S itself. Include the
leftmost bytes of S+1 to S+5, which contain 00.
Also, include the number of bytes of Service Data starting at S+6.
(If the first or last word contains just one byte of data, do not
count the empty byte in that word.)

Service Data
S+6
to
S+272
When there is Service Data (data other than the Attribute
ID), the byte-order of this data is specified in bits 12 to 15
of C+1. Up to 534 bytes (267 words) can be set.

D
Contains the number of bytes of data from words D+1 on.
Does not include the 2 bytes in word D itself.
This value does include the leftmost bytes of D+1 and D+2, which contain 00.
This value also includes the number of bytes of Service Data starting at D+3.
(If the first or last word contains just one byte of data, the empty byte in that
word is not counted.)

Contains the Source node address.
(00 to 3F hex (0 to 63) for DeviceNet))
15 12 11 8 7
D+2 0 0
Contains the service code or error code (hex).
Normal response: Returns the command's Service Code with bit 07 ON.
Error response: Returns 94 hex, regardless of the command's Service Code.

D+3 Service Data
to
D+269
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.
