The communication takes place via the I/O area. The main data of the object dictionary
are mapped into the I/O area.
Ä
Chapter 4.11 ‘In-/Output area’ on page 83
Included in the mapping is also the Acyclic Channel through which you can acyclically
access the objects of the motion module. With the acyclic access, any access to the
object dictionary is acknowledged by the motion module.

Chapter 4.12 ‘Acyclic
channel’ on page 86
The mapping cannot be changed.
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.
