This object defines the parameters for the operation of each of the DF1 ports on
the module. Refer to Configuration Data Definition (page 27) for the definition of
each parameter.
3.1.4 File
Map
Override
This object defines specific data files that will override the default map file list.
When the module is configured as a DF1 slave, there may be instances where
you cannot use the default addressing shown in section 2.3 of this manual.
The File Map Override allows you to define memory (DBReg), specific file
number (FileNo), and element number (Element). The length will determine how
many registers will follow.
For example, if you must have registers 105 to 108 of module memory set up as
addresses N45:32 to N45:35, you would set the following parameters:
DBReg = 105
FileNo = 45
Element = 32
Length = 4
