There are basically two kinds of FINS commands: Those addressed to CPU
Units and those addressed to CS-series CPU Bus Units. Among FINS com-
mands for CPU Units, there are commands addressed to the various models
of CPU Unit, such as the CS-series CPU Units, CV-series CPU Units,
C200HX/HG/HE CPU Units, and so on. The basic code system is the same,
but the detailed specifications vary according to the CPU Unit.
Among FINS commands for CS-series CPU Bus Units, there are commands
addressed to SYSMAC LINK Units, to the Controller Link Unit, and so on.
All parameters used in commands and responses are in hexadecimal, unless
otherwise specified.
Commands have the following format. This data must be stored beginning at
first command word specified as an operand (S) of the CMND(490) instruc-
tion.
