The current condition of registered abnormalities is displayed. The condition of
the selected abnormality is indicated by a blue background.
The condition diagnosis is performed.
Clicking on the button displays a pop-up to select where to acquire the data.
• Acquiring data from the equipment
It communicates with K7DD and calculates progress based on the current
data and plots it on a graph.
• Acquiring data from a file
A previously saved CSV file can be specified for acquiring data. The file
name corresponds to the date and time when the diagnosis is conducted,
serving as a timestamp for reference.
File Name: Current_yyyy-MMdd-HHmmss.csv
The progress of abnormality through condition diagnosis is represented by a
percentage and bar display and is considered to be a diagnostic result.
Pre-registered normal and abnormal conditions as benchmarks are set at 0%
and 100%, respectively.
The calculation of progress incorporates data variability through t-tests, poten-
tially leading to significant deviations from the change rate of each feature
based on the registered data's variability.
[How to view the progress]
0%: Represents the same condition as when normal data is acquired.
100%: Represents reaching the registered abnormal condition.
It is displayed by hovering over the progress graph. Text can be entered as
condition diagnosis notes, allowing you to register information such as the
weather conditions, the name of the person conducting the condition diagno-
sis, and maintenance remarks.
When these diagnostic notes are displayed, the progress in Area C dynami-
cally adjusts based on the plotted content at that specific moment.
This function performs a linear approximation based on two or more points to
predict the arrival date of an abnormal condition up to 100%.
It is represented by a blue line on the graph.
You can select the number of data points for the approximation.
Use this function when recalculating from the date of maintenance.
