초록 ▼

An apparatus includes a first interface configured to communicate over a first industrial process control network using a first protocol. The apparatus also includes a second interface configured to communicate over a second industrial process control network using a second protocol. The apparatus further includes a third interface configured to communicate with at least one supervisory device over a third network. In addition, the apparatus includes at least one processing device configured to provide concurrent access for the at least one supervisory device to process control devices coupled to the first and second industrial process control networks during a migration of process control devices that use the first protocol to process control devices that use the second protocol.

1. An apparatus comprising: a gateway including: a first interface configured to communicate over a first industrial process control network using a first protocol;a second interface configured to communicate over a second industrial process control network using a second protocol;a third interface configured to communicate with at least one supervisory device over a third network; andat least one processing device configured to provide concurrent access for the at least one supervisory device to process control devices coupled to the first and second industrial process control networks during a migration of process control devices that use the first protocol to process control devices that use the second protocol. 2. The apparatus of claim 1, wherein the second interface is configured to emulate the first protocol over the second industrial process control network. 3. The apparatus of claim 1, wherein the at least one processing device is further configured to make all of the process control devices coupled to the first and second industrial process control networks appear to be devices coupled only to the first industrial process control network. 4. The apparatus of claim 1, wherein the at least one processing device is further configured to provide substantially continuous access by the at least one supervisory device to at least one of the process control devices. 5. The apparatus of claim 4, wherein the at least one processing device is configured to provide the substantially continuous access by using a network state to identify whether requests from the at least one supervisory device are transmitted to a specified process control device via the first interface or via the second interface. 6. The apparatus of claim 5, wherein the at least one processing device is configured to track multiple network states as multiple process control devices coupled to the first industrial process control network are migrated to multiple process control devices coupled to the second industrial process control network. 7. The apparatus of claim 1, wherein: the first interface is configured to communicate over a coaxial network; andthe second interface is configured to communicate over a redundant Ethernet network. 8. A method comprising: communicating over a first industrial process control network using a first protocol via a first interface of a gateway;communicating over a second industrial process control network using a second protocol via a second interface of the gateway;communicating with at least one supervisory device over a third network via a third interface of the gateway; andproviding concurrent access, by the gateway, for the at least one supervisory device to process control devices coupled to the first and second industrial process control networks during a migration of process control devices that use the first protocol to process control devices that use the second protocol. 9. The method of claim 8, wherein the second interface emulates the first protocol over the second industrial process control network. 10. The method of claim 8, further comprising: making all of the process control devices coupled to the first and second industrial process control networks appear to be devices coupled only to the first industrial process control network. 11. The method of claim 8, further comprising: providing substantially continuous access by the at least one supervisory device to at least one of the process control devices. 12. The method of claim 11, wherein providing the substantially continuous access comprises using a network state to identify whether requests from the at least one supervisory device are transmitted to a specified process control device via the first interface or via the second interface. 13. The method of claim 12, further comprising: tracking multiple network states as multiple process control devices coupled to the first industrial process control network are migrated to multiple process control devices coupled to the second industrial process control network. 14. The method of claim 13, wherein: the process control devices coupled to the first industrial process control network comprise legacy process controllers controlling one or more aspects of an industrial process system; andthe process control devices coupled to the second industrial process control network comprise advanced process controllers controlling the one or more aspects of the industrial process system. 15. The method of claim 8, wherein: the first and second industrial process control networks comprise Level 1 networks; andthe third network comprises a Level 2 network. 16. A non-transitory computer readable medium containing a computer program, the computer program comprising computer readable program code that when executed causes at least one processing device to: initiate communication over a first industrial process control network using a first protocol via a first interface of a gateway;initiate communication over a second industrial process control network using a second protocol via a second interface of the gateway;initiate communication with at least one supervisory device over a third network via a third interface of the gateway; andprovide concurrent access, by the gateway, for the at least one supervisory device to process control devices coupled to the first and second industrial process control networks during a migration of process control devices that use the first protocol to process control devices that use the second protocol. 17. The non-transitory computer readable medium of claim 16, wherein the computer program further comprises computer readable program code that when executed causes the at least one processing device to make all of the process control devices coupled to the first and second industrial process control networks appear to be devices coupled only to the first industrial process control network. 18. The non-transitory computer readable medium of claim 16, wherein the computer program further comprises computer readable program code that when executed causes the at least one processing device to provide substantially continuous access by the at least one supervisory device to at least one of the process control devices. 19. The non-transitory computer readable medium of claim 18, wherein the computer readable program code that when executed causes the at least one processing device to provide the substantially continuous access comprises: computer readable program code that when executed causes at least one processing device to use a network state to identify whether requests from the at least one supervisory device are transmitted to a specified process control device via the first interface or via the second interface. 20. The non-transitory computer readable medium of claim 19, wherein the computer program comprises computer readable program code that when executed causes the at least one processing device to track multiple network states as multiple process control devices coupled to the first industrial process control network are replaced with multiple process control devices coupled to the second industrial process control network.
