Recommended topology
For an easy configuration and due to many possible topology variants we recommend to create
networks according to the following rules:
1. Create CN groups with up to 10 nodes.
2. Connect CN groups in star shape to the managing node.
3. Connect CN groups to the managing node via one external hub each.
• For more than 2 CN groups, use an external 8-port hub (e.g. Lenze hub E94AZCEH).
• For max. 7 CN groups one hub is sufficient.
• For more than 7 CN groups, use further hubs.
• The groups can be distributed on the hubs just as you like.
• Observe the restrictions of the used managing node.

Note!
E94AYCEP communication module als Managing Node
With maximally 2 CN groups and the use of an E94AYCEP communication module as
Managing Node, connect the CN group(s) directly to the POWERLINK terminals X211 and
X212 of the E94AYCEP communication module.
