Interfaces, bus adapters, buttons
Interfaces X1 and X2
You will find the technical specifications and assignment of the Ethernet interface X1 and the
PROFIBUS interface X2 in the section Technical data (Page 77).
Interface X3 for for bus adapter
At the top right beside the PROFIBUS interface, there is the interface X3 for bus adapters of
the ET 200SP device family.
As an alternative, you can use this interface for connection to Ethernet if, for example, you
require an optical connection to the LINK.
The interface is constructed in the ET 200SP design and pin assignment.
You will find further information in the catalog, in Siemens Industry Mall and in the system
manual of the ET 200SP, see /4/ (Page 90) and in the appendix BusAdapter (Page 85).
For information on configuring the bus adapters in STEP 7 V5 refer to the section
Configuring bus adapters (Page 56).
