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)
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. With the System SLIO motion module this object
directory is structured as follows:
Index area
0x1000 ... 0x6FFF
0x7000 ... 0x7FFF
0x8000 ... 0x8FFF
0x9000 ... 0x9FFF
Each object has a subindex 0. Calling an object with subindex 0, the
number of available subindexes of the corresponding object is returned.
You have the following options for accessing the objects in the object dictionary:
n
Access via acyclic channel
–
Any access to the object dictionary is acknowledged by the motion module.
–

Access via I/O area
n
–
The main objects are mapped in the I/O area.
–
The mapping cannot be changed.
