X127 LAN (Ethernet)

Note
Use
Ethernet interface X127 is intended for commissioning and diagnostics, which means that it
must always be accessible (e.g. for service).
Further, the following restrictions apply to X127:
• Only local access is possible
• No networking - or only local networking in a closed and locked electrical cabinet
permissible
If it is necessary to remotely access the electrical cabinet, then additional security measures
must be applied so that misuse through sabotage, unqualified data manipulation and
intercepting confidential data is completely ruled out (also see Chapter "Industrial Security
(Page 21)").

Connector
Connector type: RJ45 socket
Note
The LAN (Ethernet) interface does not support Auto MDI(X). If the LAN interface of the
communication partner also cannot handle auto-MDI(X), then a crossover cable must be
used to establish the connection.
Note
Support during commissioning
The X127 LAN interface supports commissioning and diagnostic functions. It must not be
connected for normal operation.
