Process Data Storage For Process Plant Diagnostics Development
First Claim
1. A method of data storage for a plurality of process parameters indicative of operation of a process, the method comprising the steps of:
- establishing communications with one or more data sources of process data for the plurality of process parameters;
collecting the process data for the plurality of process parameters; and
,storing the collected process data in a set of data storage files;
wherein each data storage file of the set of data storage files is arranged within a file hierarchy and dedicated to the process data collected during a specified time frame for a respective process parameter of the plurality of process parameters.

Abstract
A number of techniques are disclosed to facilitate process data collection and monitoring. The techniques may involve and support the selection of process parameters to be monitored, including scanning techniques for automated identification of such parameters. The techniques may also involve the management of data storage and archiving operations to facilitate continued process data collection arising from an on-line process. In these and other ways, the disclosed techniques are well-suited for process data collection and monitoring in connection with diagnostic elements of a process control system and other contexts involving process status indicators and the underlying process variables.
