Fault Tolerant Ethernet (FTE)
Fault Tolerant Ethernet (FTE) is the control network of PlantCruise. FTE provides fault tolerance in the network, has quick response time, determinism and the security required for industrial control applications.
FTE is a single network topology with redundancy. This redundancy is achieved using Honeywell’s FTE driver and commercially available components. The driver and FTE enabled components allow network communication to occur over an alternate route when the primary route fails. Each FTE node is connected twice to a single LAN through the dual Network interface Card as shown in the following figure 5.The network also contains redundant switches and cables.
