Commands and Responses for Controller Link Units Section 6-5
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, to C200HX/HG/HE PCs, and to
CQM1H-series PCs are explained in this manual. For explanations of FINS
commands for other Units, refer to the FINS Commands Reference Manual
(W227).
C200HX/HG/HE and CQM1H-series PCs do not directly support FINS com-
mands, but the Controller Link Unit automatically converts the command for-
mat so that C200HX/HG/HE and CQM1H-series PCs can process them. The
Unit also converts the response format so that the response can be returned
to the source of the command.
When FINS commands are sent via a Host Link System for CVM1, CV-series,
or CS/CJ-series PCs, be sure to use the command format for relaying
between networks.
