Abstract: A method of displaying fault tolerant Ethernet (FTE) status in a process control system having FTE devices in a FTE community including a plurality of Enhanced Universal Control Networks (EUCNs) each having an Enhanced Network Interface Module (ENIM). FTE cable status data is collected from the FTE devices during system operation. Responsive to receiving user's request, generating diagnostic display view data filtered by a FTE Device index including FTE status for any combination of the FTE devices or second FTE diagnostic display view data filtered by EUCN node number including FTE status for FTE devices in a user selected EUCN. The first FTE diagnostic display view data or second FTE diagnostic display view data are transmitted to a device of the user, and is then displayed on a user's display.

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.

Abstract: A method and system (200) for communicating between a first and second serial communications protocol (SCP) enabled device (202, . . . , 212, 224). The method includes the step of comparing a data block comprising a plurality of data values from the first SCP enabled device to a plurality of reference data values. The method also includes the step of determining which of the data values has changed and which of the data values has not changed. This determination is made based on the comparing step. The method further involves writing substantially only the data values that have changed to a memory of the second SCP enabled device.

Abstract: A method and system for improving communications for systems (200) including at least one communications protocol (CP) enabled server device (206, . . . , 212). The method comprises performing a first diagnostic process (400). The first diagnostic process includes classifying at least one CP enabled server device as a malfunctioning device or an operational device. The method also includes preventing the CP enabled server device from participating in write or read transactions if it is classified as a malfunctioning device in the first diagnostic process. The CP enabled server device is prevented from participating in write or read transaction until the CP enabled server devices is reclassified in a subsequent repetition of the first diagnostic process as an operational device. The method further includes performing a write or read process with the CP enabled server device if it is classified as an operational device in the first diagnostic process.
