Commands and Responses for Controller Link Units Section 6-5
Command Codes The command code consists of two bytes of data, and indicates the contents
of the command. A FINS command must begin with a 2-byte command code,
and any parameters must follow the command code.
Response Codes The response code consists of two bytes of data, and indicates the result of
the command execution. The first byte is the MRES (main response code),
which indicates the broad classification of the execution result. The second
byte is the SRES (sub-response code), which gives the detailed classification.
The following table shows the main response codes and the execution results.
For a more detailed listing of response codes, including the sub-response
codes, refer to 6-6 Response Codes.
6-4-3 Applicable Units for FINS Commands
The parameters used with FINS commands and responses depend on the
Unit to which the command is being sent. The FINS commands and
responses addressed to Controller Link Units are explained in this manual.
For explanations of FINS commands for other Units, refer to the FINS Com-
mands Reference Manual (W227).
When FINS commands are sent via a Host Link System for CVM1, CV-series,
or CS-series PLCs, be sure to use the command format for relaying between
networks.
