4.6 Interfaces of the 7KN POWERCENTER 3000
Typical devices of a smart assembly network
The interface must be multiplied for the individual devices using an industrial-type Ethernet
switch, e.g. SCALANCE. 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 the ring topology based on "MRP" (Media
Redundancy Protocol). If media redundancy is dispensed with within the smart switchgear
assembly, the Ethernet interface X2P1 can be connected directly to the Ethernet interfaces
of a Switched Ethernet PROFINET expansion module.
