The following table lists each of the memory (device) areas accessible by the Mitsubishi A-Serial Serial interface.
The Address Entry column gives the maximum device number that a particular device area could support. The actual allowed for the programmable controller being configured may be less and is dependent upon the model.
The Entry Type column specified how you should enter the device's number. Some devices are numbered/referenced by decimal numbers and others by hexadecimal.
The last column specifies how the interface treats the device area, either as bit (discrete) devices or as word devices.
