Abstract
A system facilitates state processing in an industrial control environment is provided. The system includes a module component to facilitate control operations in an industrial control environment. A propagation component is embedded within the module component to communicate state information to at least one other module component. The state information is communicated in an upward or downward direction according to a hierarchical module configuration.
Claims25
A system that facilitates state processing in an industrial control environment, comprising:
- a module component to facilitate control operations in an industrial control environment;
- and
- a propagation component embedded within the module component to communicate control information that includes fault data, mode data, reset data, or safety data to at least one other module component.
The system of claim 16, further comprising at least one safety parameter that includes a probability of failure on demand, a Spirius Trip Rate, an Availability, a Mean time between failure, a fault tolerance, a diagnostic coverage, or a systematic safety integrity component.
A method to propagate states for an industrial control process, comprising:
- generating one or more conditions associated with reset, fault, mode, or safety state conditions;
- automatically processing the conditions up or down a module hierarchy;
- and
- inheriting or propagating the conditions up or down in the module hierarchy.
A module control propagation system, comprising:
- means for communicating between modules of a hierarchy;
- and
- means for generating control data between the modules, the control data including fault data, reset data, mode data, or safety data.
