| Introduction | 2011 |
Fault Tolerant Ethernet (FTE) is proprietary protocol created by Honeywell. [1][2]
Designed to provide rapid network redundancy, on top of spanning tree protocol.[3] Each node is connected twice to a single LAN through the dual network interface controllers. The driver and the FTE enabled components allow network communication to occur over an alternate path when the primary path fails.[4][5]
Default time before failure is detected, is Diagnostic Interval (1000ms) multiplier with Disjoin Multiplier (3), for a 3000ms recovery time.
Similar to Switch Fault Tolerance (SFT) in windows and mode=1 (active-backup) in Linux.
Supported hardware and software[edit]
- Windows 7/2003 or newer
- Honeywell Control Firewall (CF9)
- Honeywell C300 Controller
- Honeywell Series 8 I/O
Technical overview[edit]
- Uses Multicast ( 234.5.6.7), for FTE community.
- Recommended maximum of 300 FTE nodes and 200 single connected Ethernet nodes (A machine with to network cards is considered as two separate single connected Ethernet nodes).
- Recommended to have separate broadcast/multicast domain , for different FTE communities.
- Recommended maximum of 3 tiers of switches.
- Default UDP Source Port: 47837
- Default UDP Destination Port : 51966
