(13) DATA BANK
Data bank objects enable the FX-40DU-E to store 16-bit data up to the maximum of 4,000 points
which corresponds to the capacity of the programmable controllers file registers. This file data
can be transferd to the programmable controller in response to input from the operation keys of
the FX-40DU-E or input from external sources.
This allows the storage of a large quantity of data (for example processing data, positioning and
travel distance data) and allows the use of a file register function with FXo series programmable
controllers, which do not have file registers.
