3.5.1 Internal Database Re-mapping
Depending on the application, you may need to copy data from one section of the
module’s internal database to another section. The [Data Map] section of the
CFG file allows a user to selectively copy data registers, one register up to 100
registers at a time, from one internal database to another. Up to 200 entries can
be made in the [Data Map] section, providing a wide and powerful range of
functionality.
3.5.2 From Address
0 to 3999
This field specifies the internal database register to copy from. This address can
range from the Data area as well as the Status Data Area of the product
3.5.3 To Address
0 to 3999
The destination for the copy is always going to be the Register Data area.
3.5.4 Register Count
1 to 100
This parameter specifies the number of registers to copy.
3.5.5 Swap Code
0, 1, 2, 3
There may be a need to swap the order of the bytes in the registers during the
copy process in order to change from alignment of bytes between dissimilar
protocols. This parameter is helpful when dealing with floating-point or other
multi-register values, as there is no standard method of storage of these data
types in slave devices.
The following table defines the values and their associated operations:
Swap Code Description
0 None - No Change is made in the byte ordering (1234 = 1234)
1 Words - The words are swapped (1234=3412)
2
Words & Bytes - The words are swapped then the bytes in each word are
swapped (1234=4321)
3 Bytes - The bytes in each word are swapped (1234=2143)
