FINS Communications
Section 6-5
The MRES codes are shown in the following table along with the results they
indicate.
Refer to the SYSMAC CS/CJ/CP/NSJ-series Communications Commands
Reference Manual (Cat. No. W342-E1) or the operation manuals for the rele-
vant unit for further information on response codes.
Command/Response Reference
This section describes the FINS commands that can be sent to PLC’s Ether-
net module and the responses to each command.
The command, response, and (where applicable) the results storage blocks
are given with the commands in graphic form as shown in the following dia-
gram. If the data is fixed, it is included in the blocks. If the data is variable, it is
described following the blocks. Each box represents 1 byte; every two boxes
represents 1 word. The following diagram shows 2 bytes, or 1 word.
The results storage format is the format used to store transfer results.
Response codes applicable to the command are described at the end of the
command description. If any UNIX error codes are generated, these are also
described. Refer to your UNIX error symbol definition file /usr/include/sys/
errno.h for details. UNIX errors are returned in the results storage area.
Note
Except for special cases, all send/receive data is in hexadecimal format.
New FINS Commands Addressed to Built-in Ethernet Port (0xFA)
Command Code List
The command codes listed in the following table can be sent to the built-in
Ethernet port.
The destination unit address (DA2) in FINS frame should be set as 0xFA.
