Application examples
6.1 Network environments
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 produced in SENTRON powerconfig 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 →
General → Internal communication (X1P2).
The smart assembly network is connected to the Ethernet interface X2P1.
Some SENTRON devices, e.g. the Switched Ethernet PROFINET extension module and
PAC3220, have 2 Ethernet ports. These devices can be directly connected using a patch cable.
This enables short cables to be used and reduces cabling work.
Note
The failure of one of the devices interrupts communication to the devices behind it. This can
be avoided by building a ring with the Switched Ethernet module PROFINET and a SCALANCE
switch with MRP (Media Redundancy Protocol).
