  • Secure data write apparatus and methods for use in safety instrumented process control systems
    Patent number: 8233998
    Abstract: Secure data write apparatus and methods for use in safety instrumented process control systems select a parameter associated with a process control element within the process control system and send first data associated with the parameter to the process control element. A confirmation associated with a request to write the first data to the process control element is received from a user and the second data is sent to the process control element in response to receiving the confirmation. The first and second data are compared at the process control element and the first or second data are written to a location in the process control element associated with the parameter if the first and second data are at least substantially identical.
