4.6.2 Application with master-slave process data transfer
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).

Fig. 4-15 Application example for master-slave process data transfer
 The SL master can read and write into all of the channels of all of the
slaves/transceiver.
Configuring data:
Function block @SL: MOD connection = 1...5 or 10
For each slave: e.g. one SLSVAV
 Each slave can read all of the channels and write into a max. of 8
(own!) channels.
Configuring data:
Function block @SL: MOD connection= 0
For each read channel: e.g. one SLAV
For each write channel: e.g. one SLSV,
Connection, FSL: Slave's own address
Connection, NSL: 1
 In order to transfer data from slaves/transceivers to
slaves/transceivers which are physically located in front in the ring, in
the same bus cycle, the slave-to-slave communications setting must
be used.
Configuring data:
Function blocks SLAV and SLDIS: Connection QV = 1
