Embodiment Construction
[0041] As described herein, various embodiments of the present invention provide systems, components, and methods (hereinafter, collectively referred to as "systems") for utilizing SIS devices in new and / or existing Fieldbus architectures. It is intended that the various systems set forth herein can be used with various types and forms of SIS devices and with various types of Fieldbus architectures. Furthermore, it may be desirable to use the various systems of the present invention in various fieldbus architectures without significant (preferably no) changes to the protocols, methods, or other processes currently utilized in the fieldbus architectures , to pass non-SIS information over the network for notification and / or utilization by network-compatible Fieldbus devices.
[0042] More specifically, one embodiment of an SIS implementation may include apparatus configured to operate in an open control system comprising: memory, including system management data; one or more SIS...
