Using the Memory Address Map
When connected to a CPU-CAxx(FIT)GY, the ADI16-4(FIT)GY can be accessed by a host computer
through a network. In addition, the Module can be allocated to the memory controlled by the
Controller Module according to a given Device ID. Applications running on the host computer control
the I/O modules by reading/writing the memory that is controlled by the Controller Module.
For detailed specifications on the memory controlled by the Controller Module, see the Controller
Module manual.
Following is an explanation of the memory areas necessary for the use of the ADI16-4(FIT)GY: the
"module settings area", the "module information area", and the "basic input data area".
Module Settings Area
This area controls the settings and how the module is started.
The module becomes available when the necessary settings are written into this area and the module
activation option is set in the [module startup register].
Module Information Area
The current module settings are stored in this area.
When the Module is started, the contents of the Module Settings Area are copied to the Module
Information Area. By reading this area, you can verify the current module settings.
Basic Input Data Area
Basic input data is read in this area.
