Tools>Data Analysis Explained

The data analysis is a visualization tool with an export function.

 

Important feature: within the data analysis, it is possible to check and generate data gaps.

 

Print Screen 1

Under navigation the user can select a time frame.

Under groups the user can select one or more groups (SHIFT or CONTROL).

The user can then select one or more measuring points (SHIFT or CONTROL).

 

Various visualizations are then available. When first opening the page, the chart visualization is selected. A chart of the selected measuring points over the selected time period will appear. The chart is limited to 1 million measurements (for example, at a 10s measurement interval, roughly only 4 months of data will be shown).

 

When a chart is selected, an alarm band can also be selected. All alarm bands of all selected measuring points will appear in a drop down menu when selecting alarm bands.

 

Important:

The user can change the size of the groups/measuring points and visualization compartments.

The chart line will only be empty if a data gap is detected and "---" is stored within the database. Until this time a straight line will join the last and first values.

The setup (time frame and measuring points) can be exported in various formats:

CSV report.

PDF report.

JSON report.

Batch Release/Certification report.

Print Screen 6

When exporting a PDF, the system offers the option to name the PDF, add an extension to the file name (current time, from time, to time and from and to time) and select a report template.

Data Analysis New+Export+PDF Report

 

Limitation: Limit violations is limited to 1'000 warning and 1'000 alarm limit violations.

Print Screen 7

When exporting a Batch Release/Certification report the system offers the option to add a batch number, select the type of report (master batch report or production batch report), add the product as well as other details and comments. The user can select the option to add the chart trend lines.

 

The user can select the option to review the report. The preview can be done to review the report before adding comments. If only preview is selected, the creation of the report is not included within the audit trail and the document is not created (DOC-XX). Only when clicking on create will the document officially be created under the audit trail and will obtain a DOC-XX number.

Limitation: Limit violations is limited to 1'000 warning and 1'000 alarm limit violations.

Print Screen 8

The visualization can also be setup as a table view. A table of the selected measuring points over the selected time period will appear.

Data Analysis New+Table

Print Screen 9

The visualization can also be setup as a statistics view. A statistics view of the selected measuring points over the selected time period will appear.

Data Analysis New+Statistics

 

The following statistics are shown:

Number: Number of measured values within the selected time frame.

Min.: Minimum value, including date and time that it occurred within the selected time frame.

Max.: Maximum value, including date and time that it occurred within the selected time frame.

Average: Average value within the selected time frame.

Std. dev.: Standard deviation within the selected time frame.

Mean kinetic temperature: Mean kinetic temperature within the selected time frame.

Cp & CpK: Process capability within the selected time frame.

oThe Cp is only applicable when high and low alarm limits are set for the measuring point,

oWarnings are not taken into consideration,

oNo results will be shown if the alarm levels changed during the selected time frame,

oThe high limit must be higher than the low limit.

 

The number of digits shown within the statistics will correspond to the "display digits" of the measuring points: Tools>Setup>Measuring Points Explained.

Print Screen 10

The visualization can also be setup as an alarm view. A view of all warnings and alarms of the selected measuring points over the selected time period will appear.

Data Analysis New+Alarms

Print Screen 11

The visualization can also be setup as a limit violations view. A view of all warning and alarm limit violations of the selected measuring points over the selected time period will appear (limited to 500).

Data Analysis New+Limit Violations

Print Screen 12

The visualization can also be setup as a data gap view. In this case, the software will check the data on the database meaning that the system will check to ensure that all of the data is available.

 

A view of all data gaps (limited to 500) will appear stating:

From.

To.

Duration.

Measuring point ID.

Device ID.

Data gap event ID.

Status:

oDownload pending: A readout command is open.

oReported: An open data gap reminder is available.

oCommented: A commented data gap reminder is available.

oConfirmed: A confirmed data gap reminder is available.

oConfirmed QA: A confirmed QA data gap reminder is available.

oDisabled: The device/measuring point was disabled during this time.

oNot reported: An unexpected data gap occured.

oNo datagap: A data gap event is available, but the data is available.

Action link.

 

The user has the possibility to click on the action link:

Create a data gap event:

oA new pending data gap event will be opened.

oThe user requires sufficient rights (add event).

Retry to download the data from the device:

oOnly possible for a reported or commented data gap.

oOnly possible to download one data gap at a time.

oA readout command is triggered and visible within the audit trail.

oThe user requires sufficient rights (retry event).

Close data gap:

oData gap events with no data gaps can be closed.

oThe user requires sufficient rights (close event).

 

Limitation: A change of the measuring interval within the selected time span will not be detected and results in a lot of false not reported data gaps or not detected existing data gaps.
