MELSEC-A series programmable controllers have a parameter which is used to
designate functions and device use ranges.
The functions and device use ranges are determined by the parameter values.
The parameters of CPU are set to default values. If the default can be used for the
purpose, it is not necessary to set the parameter.
The user’s programs for the MELSEC-A series PCs are classified as follows.
ACPU Programming Manual (fundamental) gives the programs which can be used
