Note
A signal source (BO) can be connected to any number of signal sinks (BI).
A signal sink (BI) can only ever be connected to one signal source (BO).
The BICO parameter interconnection can be implemented in different Command
Data Sets (CDS). The different interconnections are activated by switching data
sets. Interconnections across drive objects are also possible.
Internal encoding of the binector/connector output parameters
The internal codes are needed, e.g., in order to write BICO input parameters via
PROFIBUS.
