This program is designed to post-process binary data files created by the Plant Data Recorder Retrieval program (PDRSrtrv). The binary data file(s) to be processed should (at least) contain the data points to be scanned. The file(s) may contain extra points, they will be ignored.
Initial Main Program Window
The input to the program may be given in any order except, of course, the "Run Scan" button will not work correctly until everything else is specified.
Vibration data may be selected by specifying one or two limits, and the relation between the limits (when two are specified). Note that some combinations don't make much sense, like (Greater than X) OR (Less than Y) when X<Y. However, the program will dutifully perform the tests specified and select any point that meets the criteria.
There are two checkboxes just belong the data selection rules that also affect which values are used. Normally, point values that were recorded when the point was off scan are not tested. Checking the "Include Off Scan Values" box causes the program to test off scan values the same as on scan values. Normally, manual (or substituted (if our programmer could spell)) values are ignored by the program. Checking the "Include Manual/Substatuted Values" (misspelling intentional to match silly programmer's dialog) box causes the program to treat substituted values the same as normal, on scan values.
Use the PDRSrtrv program to output one or more BINARY files that contain the data points of interest. You may specify more than one source file for VibrAnal, it will attempt to process all of the files listed.
VibrAnal uses point group files created using the USEC Group Editor (gEdit). Only ONE group may be used at a time, although the group may include any number of points.
Main Window (in use)
At this point, all three of the inputs have been specified, the "Run Scan" button will now work. Pressing it will cause the program to display a dialog allowing you to name the result file, then it will scan the source file(s) for the points contained in the group for values meeting the selection criteria. When the program has finished processing the source file(s), it will present a result summary, similar to the one below:
Result Report
The summary shown indicates that none of the point records in the source file(s) met both the point and data selection criteria. It may be that the source(s) used had a different set of points, and/or it may be that none of the values met the data selection rules.
When a number of anomaly records is emitted, they will be in CSV (Comma Separated Value) format, similar to the following example output:
2003-11-05 15:26:45,C35.U3.V15,0.0026376 2003-11-05 15:26:45,C35.U3.V21,0.0064056 2003-11-05 15:26:45,C35.U3.V23,0.005024 2003-11-05 15:26:45,C35.U3.V24,0.0057776 2003-11-05 15:26:45,C35.U3.V25,0.0077872 2003-11-05 15:26:46,C35.U3.V29,0.0020096 2003-11-05 15:26:46,C35.U3.V31,0.0001256 2003-11-05 15:26:46,C35.U3.V32,0.0066568 2003-11-05 15:26:46,C35.U3.V33,0.0001256 2003-11-05 15:26:46,C35.U3.V34,0.0021352 2003-11-05 15:26:46,C35.U3.V35,-0.0001256 2003-11-05 15:26:46,C35.U3.V39,0.00314 2003-11-05 15:26:46,C35.U3.V41,0.0027632 2003-11-05 15:26:46,C35.U3.V43,0.0066568 2003-11-05 15:26:46,C35.U3.V44,0.0047728 2003-11-05 15:26:46,C35.U3.V45,0.0032656 2003-11-05 15:26:46,C35.U3.V49,0.0032656 2003-11-05 15:26:46,C35.U3.V51,0.004396 2003-11-05 15:26:46,C35.U3.V53,0.0051496 2003-11-05 15:26:46,C35.U3.V54,0.0057776
The first column contains the date/time that the value was read by the front end gear. The second column contains the point name and the third column contains the value. CSV format is a common data sharing format that is recognized by most spreadsheets and databases. The exact format of the date/time value was selected because it is understood by Microsoft® Excel, one of the most commonly used spreadsheets.
