Eachnode must be assigned a different number. Enter the numbers in ascending order startingwith 1.● If p8836 is set to 0, the nodes and the complete following line is shut down for SINAMICSLink.● Gaps in the numbering are not permitted, as then SINAMICS Link would not function.● The node with the number 1 is automatically the sync master of the communication link.● The ports of the CBE20 must be interconnected strictly in accordance with the abovediagram. You must always connect port 2 (P2) of node n with port 1 (P1) of node n + 1.● In the "SINAMICS Link" mode, ports 3 and 4 of the CBE20 can only be used to connect tothe STARTER commissioning tool or Startdrive.CommunicationA.1 CommunicationIndustrial Security206 Configuration Manual, 08/2017, A5E36912609A
