X127 LAN (Ethernet)

Note
Application
Ethernet interface X127 is intended for commissioning and diagnostics, which means that it
must always be accessible (e.g. for service).
Furthermore, the following restrictions apply to X127:
● Only local access is permissible
● No networking - or only local networking is permissible in a locked control cabinet
If remote access to the control cabinet is required, then additional security measures must be
taken to prevent misuse through sabotage, unqualified data manipulation and intercepting
confidential data (see also the Chapter "Industrial Security (Page 9)").
Table 3-22
Connector type: RJ45 socket
Note
The LAN 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.
For diagnostic purposes, the X127 LAN interface features a green and a yellow LED. These
LEDs indicate the following status information:
