Terminology

Term
AIC It is a package name indicating the AI Controller.
AI Operator It is a tool to configure the AI function settings of the AI Controller as well as to monitor the status.
AI machine learning It is the data to monitor existence of equipment events by the AI Controller.
model
AI Viewer It is a tool to visualize feature values and results of equipment events that are output by the Fea-
ture Value/Machine Learning Function. The AI Operator reads out data transferred from the AI Con-
troller and displays it on a computer for the users to view.
AI Predictive Mainte- It is one of the function components of the Sysmac Library in order to use the AI functions of the AI
nance Library Controller.
Isolation Forest It is an algorithm used for quantifying the degree of deviation from the normal range.
For the AI Controllers, it is used for calculating equipment event monitoring scores.
TimeSeries It is a unit of databases that are used in the Time Series Database Function.
It is the database used for storing values of the variables in chronological order before generating
an CSV file.
TSDB It is a package name meaning TimeSeries DataBase.
WAC It is a package name meaning WebAPI Connection.
WebAPI Connection It is a function designed to transfer files from the AI Controller to the web server periodically.
Function
machine learning It is a variable that is used to link an equipment event monitoring result with a frame.
output frame varia- When an equipment event is output, a value of the corresponding frame variable is also output to
bles this variable.
server certificate It is an X.509 electronic certificate that certifies a web server.
A web server generates and manages this certificate along with the secret key of the certificate.
subframe It is a more detailed time range that is targeted for calculation within a frame.
Time Series Data- It is a function designed to collect variables and calculation result data of the Feature Value/
base Function Machine Learning Function in chronological order.
equipment event It refers to a certain event that occurs on the equipment.
It includes equipment events that will lead to quality problems and productivity problems (e.g. minor
stops).
equipment event It is the judgment result indicating if an equipment event is present. It consists of the level (Normal,
monitoring result Alarm Level 1, Alarm Level 2) and the equipment event monitoring score.
Equipment event It is a file containing the equipment event monitoring results that were calculated by the Feature
monitoring result file Value/Machine Learning Function.
The file name is AIS-****.csv (**** is time data).
equipment event It quantifies the degree of the existence of an equipment event.
monitoring score The larger value indicates that an equipment event is present.
feature extraction It is a variable that is used to link a feature value with a frame.
output frame varia- When a feature value is output, a value of the corresponding frame variable is also output to this
bles variable.
feature value It is the data indicating the feature of variable data.
feature value calcu- It is a conversion method for obtaining a feature value from variable data. The examples of meth-
lation method ods include averaging and standard deviation.
Feature Value/ It is a function that extracts features and patterns from the running equipment and determines
Machine Learning whether equipment events occur based on the extracted results and the AI machine learning mod-
Function el.
