Service Data
Class ID (hex)
Instance ID (hex)
Attribute ID (hex)
Set the number of bytes of source data from words S+1 on.
For example, set S to 0008 hex if there are 4 words of data
(S+1 to S+4). Do not include the 2 bytes in word S itself.
Include the leftmost bytes of S+1 to S+4, which contain 00.
Also, include the number of bytes of Service Data starting at
S+5. (If the first or last word contains just one byte of data, do
not count the empty byte in that word.)

Destination Node Address 00
to max. node address (hex)
(00 to 3F hex (0 to 63) for
DeviceNet)
If the Attribute ID is not used, set it
to FFFF hex. (The Attribute ID
cannot be set to 0000 hex.)
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.

Response monitoring time
Explicit message format
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+5
0 hex: Stored from leftmost byte (Left → Right → Left → Right ...)
8 hex: Stored from rightmost byte (Right → Left → Right → Left ...)
0001 to FFFF hex (0.1 to 6553.5 s)
0000 hex: 2 s (default setting)
0000 hex: DeviceNet (same as using the 2801
FINS command)
