Abstract
A method of displaying fault tolerant Ethernet (FTE) cable status in a process control system having FTE devices in an Enhanced Universal Control Network (EUCN) including an Enhanced Network Interface Module (ENIM) on a UCN status display. Updated FTE cable status is obtained from each of the FTE devices during operation of the process control system. The updated FTE cable status from each of the FTE devices is stored in a memory. A UCN cable status word (CSW) including cable status bits allocated for representing the updated FTE cable status is compiled for each of the FTE devices, wherein locations for the cable status bits in the UCN CSW are used by the UCN status display to show changes in cable status. The UCN CSWs are read at a node having the UCN status display, and the updated FTE cable status is displayed on the UCN status display.
