Connection Procedure - ABB FENA-01 User Manual



Connection procedure

1. Connect the network cable to the RJ-45 connector (X1) on the
adapter module.
2. If you want to create a daisy chain with FENA-21 adapter
modules, connect the X2 connector of the first adapter module
to X1 on the next adapter module, and so on.
Note: If a device in the daisy chain is powered off or fails, the rest
of the chain is disconnected from the network. In applications
where this is not acceptable, consider using the ring topology
instead.
