10.6.2 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.
Figure 10-47 Maximum topology
● If SINAMICS Link is set, then CBE20 always operates via IF1.
● The integrated bus interfaces of a Control Unit, for example, for PROFIBUS or
PROFINET, then operate via IF2.
● The number of the respective node must be entered manually in parameter p8836. Each
node must be assigned a different number. Enter the numbers in ascending order starting
with 1.
● If p8836 is set to 0, the nodes and the complete following line is shut down for SINAMICS
Link.
● 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
2000 µs.
● 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
diagram. You must always connect port 2 (P2) of node n with port 1 (P1) of node n+1.
● Ports 3 and 4 of the CBE20 are shutdown in the SINAMICS Link mode.
