System and method of securing a process control instrument of a process control system. An authorization server is configured to authenticate the process control instrument based on a unique secure code provided to the server in response to the process control instrument entering an enhanced secure mode as determined by a switch setting. In response to being authenticated in the enhanced secure mode, the process control instrument is configured to operate in a configuration state in which an authorized user is granted access to configure the security details of the process control instrument.

Enhanced security of process control instruments

A menu navigation engine that enables user configuration of a vortex flowmeter. The vortex flowmeter includes a memory device and a processor, among other hardware components. Software instructions stored on the memory device and executable by the processor implement the menu navigation engine by displaying use case identifiers on the user interface, receiving selections of use case identifiers via the user interface, generating a formatted hierarchical tree of vortex flowmeter configuration nodes associated with the selected use case, and displaying the generated tree on the user interface.
