1: MSAC_C1 connection is activated
The MSAC_C2 connection can be used either by the C1 master (which communicates with
the slave cyclically) or by a C2 master (which then only communicates with the slave
cyclically), and has its own establishment of connection. The parameters at the establishment
of the MSAC_C2 connection (Feature_Supported, Profile_Feature_Supported,
Profile_Ident_Number, etc.) are not examined, and the parameters of the request are
mirrored in the response.
Slot_Number = 0 addresses PROFIBUS coupler data, Slot_Number > 0 addresses the data
of the function module(s).
PROFIBUS coupler data (Slot_Number = 0)
The data associated with the PROFIBUS coupler is addressed via an index:

Function module data (Slot_Number > 0)
Depending on the type of function module, access is made either to the registers (max. 4
channels, each with 64 registers) or to the parameters (only supported by a few function
modules, where the quantity of data is insufficient for the register model)
