The System SLIO motion module provides its data, such as "Profiling target position" via
an object dictionary. In this object dictionary the objects are organized and addressable a
unique number consisting of Index and Subindex. The number is specified as follows:
0x Index (hexadecimal) - Subindex (decimal)
Example: 0x8400-03
To improve the structure and for expansion at System SLIO Motion
Module another object numbering (index-assignment) is used besides the
standard CiA 402.
By separating into Index and Subindex a grouping is possible. The individual areas are
divided into groups of related objects. This object dictionary is structured as follows for
the System SLIO motion modules:
Index area Content
0x1000 up to 0x6FFF General data and system data
0x7000 up to 0x7FFF Data of the digital input and output part
from 0x8000 Data of the axis or drives
Information about the structure of the object dictionary can be found in
the manual of your motion module.
Each object has a subindex 0. Calling an object with subindex 0, the
number of available subindexes of the corresponding object is returned.
The motion modules occupy a certain number of bytes in the I/O address area.

Process data Acyclic channel
Via the Acyclic channel you can perform acyclic read and write commands. For this in the
input/output area of the motion modules a data area for the acyclic communication was
implemented. This area includes 8bytes output and 8bytes input data. When the blocks
are used, communication takes place via the Acyclic channel.
The data exchange with the motion module must be consistent over the
length of the input or output data! It is recommended to control it via the
process image. You can also use SFC 14 and 15 to consistently read and
write the input or output data.
