C: First control word
Specifies the first of four control words (C to C+3).
Operand Specifications
Description Sends the “read information/status” explicit message command (stored in
words S+1 to S+3) to the node address specified in S, via the Communica-
tions Unit with the FINS unit address specified in bits 00 to 07 of C+1.

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)
