The software program should be menu-driven with clear online user instructions. The program should protect the user from distorting or deleting stored data. Some of the predictive maintenance systems are written in DBASE software shells. Even though these programs provide a knowledgeable user with the ability to modify or customize the structure of the program . report formats they also provide the means to distort or destroy stored data. A single key entry can destroy years of stored data. Protection should be built into the program to limit the user s ability to modify or delete data and to prevent accidental database damage. The program should have a clear plain language user s manual that provides the logic and specific instructions required to set up and use the program. Automatic Trending. The software program should be capable of automatically storing all acquired data and updating the trends of all variables. This capability should include multiple parameters not just a broadband or single variable. This will enable the user to display trends of all variables that affect plant operations. Automatic Report Generation. Report generation will be an important part of the predictive maintenance program. Maximum flexibility in format and detail is important to program success. The system should be able to automatically generate reports at multiple levels of detail. At a minimum the system should be able to report A listing of machine-trains or other plant equipment that has exceeded or is projected to exceed one or more alarm limits The report should also provide a projection to probable failure based on the historical data and last measurement. A listing of missed measurement points machines overdue for monitoring and other program management information These reports act as reminders to ensure that the program is maintained properly. A listing of visual observations Most of the .
