Abstract
A management system (managing field devices of a process control plan) provided according to an aspect of the present invention enables a user to view historical menus (i.e., the menus as displayed at desired prior time points). Such a features is enabled in an embodiment by storing displayed tree structure as well as associated item values.
Claims20
A method of enabling a user to manage a plurality of field devices contained in a process control plant, said method comprising:
- receiving from said user inputs indicating a time point, a tree portion, and a field device of interest, said field device being contained in said plurality of field devices;
- receive from a data storage data representing a tree structure corresponding to said tree portion at said time point for said field device,
- displaying said tree structure as a menu.
A method of enabling a user to manage a plurality of field devices contained in a process control plant, said method comprising:
- retrieving from a field device a plurality of values, which are displayed associated with a menu;
- and
- storing data representing said menu along with said plurality of values in a non-volatile storage such that said menu can be displayed later.
A computer readable medium carrying one or more sequences of instructions for causing a system to enable a user to manage a plurality of field devices contained in a process control plant, wherein execution of said one or more sequences of instructions by one or more processors contained in said system causes said one or more processors to perform the actions of:
- receiving from said user inputs indicating a time point, a tree portion, and a field device of interest, said field device being contained in said plurality of field devices;
- receive from a data storage data representing a tree structure corresponding to said tree portion at said time point for said field device,
- displaying said tree structure as a menu.
A computer readable medium carrying one or more sequences of instructions for causing a server to enable a user to manage a plurality of field devices contained in a process control plant, wherein execution of said one or more sequences of instructions by one or more processors contained in said server causes said one or more processors to perform the actions of:
- retrieving from a field device a plurality of values, which are displayed associated with a menu;
- and
- storing data representing said menu along with said plurality of values in a non-volatile storage such that said menu can be displayed later.
