Abstract:
1. A method for accessing data of a slow network interconnected with a fast network, wherein said data comprises parameters of a plurality of devices that monitor or control a process, said method comprising: (a) providing a cache and a cache manager in a gateway interface device disposed between said fast network and said slow network, wherein said devices are connected in said slow network to monitor or control said process; and (b) operating said cache manager to populate said cache with said parameters based on requests received via said fast network from clients of said fast network and to refresh the populated parameters of each of said devices independently of one another; wherein said fast network comprises a native network that comprises at least one native device that also monitors or controls said process, wherein said slow network comprises a non-native network in which said non-native devices are connected, and wherein a condition monitored by said native device is communicated to said gateway interface device for control of at least one of said non-native devices.
