The automation system with SIMOLINK interface is generally configured
as the SL master. Whereby, all of the other coupling nodes are set as
slaves/transceiver (refer to MASTERDRIVES option module SLB
SIMOLINK).
The number of channels used for each slave/transceiver is defined by the
SIMOLINK function blocks (connections CTV, CSV).
