System- and communication configuring D7-SYS - SIMADYN D
Edition 12.2003
3.17.2 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).

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
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
