Control Units and operating elements
4.4 Control Unit CU320-2 DP (PROFIBUS)
There are two ways to set the PROFIBUS address:
1. Using the STARTER commissioning tool (parameter p0918)
– To set the bus address for a PROFIBUS node using STARTER, first set the rotary code
– Then set the address to a value from 1 to 126 using parameter p0918.
2. Using the PROFIBUS address switches on the Control Unit
– The address is set manually to values from 1 to 126 using the rotary coding switches. In

Further information for setting the PROFIBUS address is available in the SINAMICS S120 Function
Manual "Drive Functions".

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").
