Topology

Only a line topology with the following structure is permitted for SINAMICS Link.
Figure 6-45
The following entries must be made in the expert list of the Control Units:
● The numbers of the various nodes are entered into parameter p8836 in ascending order,
● Gaps in the numbering are not permitted.
● The associated IP addresses are entered automatically and they are visible in r8951.
● The node with the number 1 is automatically the sync master of the communication link.
● For non-synchronized operation (p8812[0] = 0), a maximum of 64 nodes are possible
● For synchronized operation (p8812[0] = 1), a maximum of 16 nodes (p8811 = 16) with
● For the CBE20 connection, the ports must be used as shown in the diagram above – this
● Ports 3 and 4 of the CBE20 are deactivated for communication via SINAMICS Link.
