Topology

Only a line topology with the following structure is permitted for SINAMICS Link. You must
manually set the parameters in the expert lists of the Control Units and drive objects. To do
this, use the STARTER commissioning tool.

● If SINAMICS Link is set, then CBE20 always operates via IF1.
● The integrated bus interfaces of a Control Unit, for example, for PROFIBUS or
● The number of the respective node must be entered manually in parameter p8836. Each
● If p8836 is set to 0, the nodes and the complete following line is shut down for SINAMICS
● Gaps in the numbering are not permitted.
● The associated IP addresses are assigned automatically, but are however not visible.
● The node with the number 1 is automatically the sync master of the communication link.
● A maximum of 64 nodes are possible for a communication cycle between 1000 µs and
● A maximum of 16 nodes are possible in the isochronous mode at 500 µs.
● The ports of the CBE20 must be interconnected strictly in accordance with the above
● Ports 3 and 4 of the CBE20 are shutdown in the SINAMICS Link mode.

Configuring and commissioning

When commissioning, proceed as follows:
1. Set the Control Unit parameter p0009 = 1 (device configuration).
2. Set the Control Unit parameter p8835 = 3 (SINAMICS Link).
