Siemens SENTRON 7KN POWERCENTER 3000 Manual page 65

Some SENTRON devices, e.g. the Switched Ethernet PROFINET extension module, have 2
Ethernet ports. These devices can be directly connected using patch cables. This enables
short cables to be used and reduces cabling work. For this purpose, an Ethernet switch is
used that supports ring topology based on "MRP" (Media Redundancy Protocol) to handle
failure of a device. If MRP is not used, the devices downstream of the failed device are left
without communication.
The smart assembly network is connected to the internal Ethernet interface X2P1 of the 7KN
Powercenter 3000.
To commission the SENTRON devices, a free Ethernet interface should be used for a PC
with powerconfig on the smart assembly network.
The splx file that is produced during commissioning is transferred in full to the
7KN Powercenter 3000. 7KN Powercenter 3000 then recognizes all connected devices.
Note
At the internal interface, all services, e.g. Web user interface, Modbus gateway are activated
on delivery. For this reason, commissioning for the first time must be performed via the
internal Ethernet interface X2P1.
Unwanted services should be deactivated for security reasons (= hardening). See Settings →
Actions → Services.
The smart assembly network is connected to the Ethernet interface X2P1.
