Overview of the Data Areas
■
CIO Area
It is not necessary to input the “CIO” acronym when specifying an address in
the CIO Area. The CIO Area is generally used for data exchanges, such as
I/O refreshing with PLC Units. Words that are not allocated to Units may be
used as work words and work bits in the program.
Note
The parts of the CIO Area that are labelled “not used” may be used in pro-
gramming as work bits. In the future, however, unused CIO Area bits may be
used when expanding functions. Always use Work Area bits first.
I/O Area (Inputs: CIO 0 to CIO 16, Outputs: CIO 100 to CIO 116)
These words are allocated to built-in I/O terminals of CP1H CPU Units and
CPM1A Expansion Units or Expansion I/O Units. Input words and output bits
that aren’t allocated may be used in programming.
Built-in Analog Input Area (Built-in Analog Inputs: CIO 200 to CIO 203,
CIO 210 to CIO 211) (XA CPU Units Only)
These words are allocated to built-in analog I/O terminals of CP1H XA CPU
Units. Words that aren’t used in data links may be used in programming.
Data Link Area
These words are used when the Controller Link auto-setting area is set to the
link area or for PLC links. Words that aren’t used in data links may be used in
programming.
