Typical configuration example for redundant plant bus

The plant bus and the terminal bus for multi-user systems with client/server architecture are implemented with Industrial Ethernet, a powerful area and cell network for industrial applications in line with the international IEEE 802.3 standard (Ethernet). Bus structures with optical rings are particularly suitable for this because of their high noise immunity and high availability.

In medium-sized and large plants with high requirements, SIMATIC PCS 7 applies modern FastEthernet and Gigabit technology. This combines the high reliability of optical rings with the scalable performance of switching technology and high transmission rates of up to 10 Gbps.
