4.1 Basics
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. With the System SLIO motion module this object
directory is structured as follows:
Index area
Content
0x1000 ... 0x6FFF
General data and system data
0x7000 ... 0x7FFF
Data of the digital input and output part
0x8000 ... 0x8FFF
Data drive 1
0x9000 ... 0x9FFF
Data drive 2
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.
–
Chapter 4.12 ‘Acyclic channel’ on page 86
n
Access via I/O area
–
The main objects are mapped in the I/O area.
–
The mapping cannot be changed.
–
Chapter 4.11 ‘In-/Output area’ on page 83
Please note if you write via the Acyclic Channel to objects, which are
mapped in the I/O area, these values are overwritten with the next cycle.
