Mapping
NOTICE
Viewpoint
Please note that the description of the input and output values is written
from the perspective of the module and not from the perspective of the
overall system or controller.
è
Output: Values that the module sends to the fieldbus or application.
è
Input: Values that the module receives from the fieldbus or application.
You can configure standard values that the Data Broker writes in the
relevant output register instead of an input register in the event of a
failure of a data provider. That has the advantage that the data
processing cannot abort uncontrollably.
The module uses the Little Endian byte order for the internal
processing. You can also configure the Data Broker so that it
exchanges the high and low byte when copying if necessary. To do
this, add the value 0x8000 or 32768 for the required mapping area
(see details below).
Extended Mapping
Some applications work with data that is viewed bit by bit. To make
the mapping for such applications even more flexible, an "Extended
Mapping" is provided. This mapping basically works in the same way
as the mapping described above:
