Service Data
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.)
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.

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.
FINS unit address of relaying Communications Unit.
CPU Bus Unit: 10 to 1F hex (unit number + 10 hex)
Special I/O Unit: 20 to 7F hex (unit number + 20 hex)
Port number of the communications port (logical port) for the network
instruction: 0 to 7 hex (F hex: Automatic allocation)
Byte order of service data (frame data) stored in areas beginning at S+6 and D+3
0 hex: Stored from leftmost byte (Left → Right → Left → Right ...)
8 hex: Stored from rightmost byte (Right → Left → Right → Left ...)
Response monitoring time
0001 to FFFF hex (0.1 to 6553.5 s)
0000 hex: 2 s (default setting)
Explicit message format
0000 hex: DeviceNet (same as using the 2801 FINS
command)
