  • SYSTEM AND METHOD FOR IMPLEMENTING TIME SYNCHRONIZATION MONITORING AND DETECTION IN A SAFETY INSTRUMENTED SYSTEM
    Publication number: 20090112336
    Abstract: An apparatus, system and process is provided from communicating safety-related data, over an open system, from a sender to a receiver. Safety-related components, including function blocks, flexible function blocks, resource blocks and transducer blocks, as well as, safety-related objects are provided. Also, a time synchronization monitor is provided for monitoring timing distributions and determining when such distributions have drifted beyond an acceptable limit.
    Type: Application
    Filed: December 23, 2008
    Publication date: April 30, 2009
    Inventors: Joseph D. Duffy, Ram Ramachandran, John Carl Gabler
  • SYSTEM AND METHOD FOR IMPLEMENTING SAFETY INSTRUMENTED SYSTEMS IN A FIELDBUS ARCHITECTURE
    Publication number: 20090105849
    Abstract: An apparatus, system and process is provided for communicating safety-related data, over an open system, from a sender to a receiver. Safety-related components, including function blocks, flexible function blocks, resource blocks and transducer blocks, as well as, safety-related objects are provided. Also, an extended safety-related protocol provides for authenticating communications between safety-related components over an existing black channel, such as one using a fieldbus Architecture.
