Section 3-25
D: First word of received message
Specifies the first word of the received message (D to D+269 max.).
C: First control word
Specifies the first of four control words (C to C+3).

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.
to
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.
Contains the Source node address.
(00 to 3F hex (0 to 63) for DeviceNet))
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.)

Set the total number of words of response data beginning at D.
The allowed setting range is 0 to 010E hex (270 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 10 hex)
Special I/O Unit: 20 to 7F hex (unit 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

Response monitoring time
0001 to FFFF hex (0.1 to 6553.5 s)
0000 hex: 2 s (default setting)

FINS command)
