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. We
recommend that you use the STARTER commissioning tool for this purpose.

● Manually enter the numbers of the various nodes into parameter p8836 in ascending
● If p8836 is set to 0, the participants and the complete following line is shut down for
● 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.
