Per default, one class-1 master and one class-2 master connection with
244Byte data (4Byte DP-V1 header plus 240Byte user data) are supported.
The class-1 master connection is established together with the cyclic
connection and is activated via the parameterization. The class-2 master
connection can be used by a C2 master that then communicates with the
slave only acyclical and provides an own connection establishment.
At access to the DP-V1 coupler via Slot_Number = 0 you have access to
the following elements via Index:
