Memory structure
The memory structure manages each own area for couplers and modules are to efficiently manage data.
This separates the coupler from the module's data area, making the module's data format has no
limitation. It also helps the coupler and modules are freely add data if they have diagnosis function.
In other words, the coupler independently manages the module's data in an order that the
modules are connected. And it provides information that appropriately processed, requested from
the host device (master of field network or DAQMaster).
In addition, the coupler provides input and output information of the unit in accordance with the
data size set in the field network. When the diagnosis function is activated, the coupler provides
data embed with additional input area.
