Item Description
AI Functions Time Series
Database
Function
The Time Series Database Function collects values of user-specified variables and
calculation results of the Feature Value/ Machine Learning Function into the storage
for each sampling interval. This function allows you to collect data such as variable
values to the storage without program. The collected data can be checked on the AI
Viewer. In addition, the data can be transferred to a web server by the WebAPI
Connection Function.
Feature Value/
Machine
Learning
Function
The Feature Value/Machine Learning Function determines whether equipment events
occur from the collected data and AI machine learning model. It consists of the
Feature Extraction Function and the Machine Learning Function. The Feature
Extraction Function calculates feature values from data. The Machine Learning
Function on the other hand is designed to determines whether equipment events
occur from feature values and AI machine learning model.
WebAPI
Connection
Function
The WebAPI Connection Function transmits data (CSV files) that is collected by the
Time Series Database Function in the AI Controller to a web server periodically. This
function can be used to transfer files that is collected by the Time Series Database
Function to a web server and to save and analyze data. Considering that data will be
transmitted via Internet, data is encrypted in the transmission path to the web server.

*1. The Time Series Database Function uses two variables with a Retain attribute in the system. The maximum number of
available variables with a Retain attribute is 39,998.
*2. A record refers to a set of data saved in the TimeSeries in a sampling task. It corresponds to a row in the exported CSV
file.

Item Specifications
Function
specifications
Execution trigger File transfer can be executed in the period specified by a
user on the AI Operator.
Destination specification Specify a URL of the server to which files are transferred.
Specify a URL starting with http:// or https://.When you specify
https://, SSL/TLS
communications are established.
File deletion after transfer Once the file has been transferred to the Web server
successfully, the WebAPI Connection Function deletes the
file in the AI Controller.
Connection check function To check the connection with the Web server, a file transfer
can be triggered by the AI Operator at a given timing. Refer to
NX/NY-series Artificial Intelligence Machine Automation
Controller User’s Manual (Cat. No. W594) for details.
Transfer specifications If there is more than one file to transfer at the transfer timing,
all the files are transferred.
If the last file transfer is in progress and the next file transfer
timing arrives, the execution of the last file transfer continues.
Transfer protocol The file transfer executes in accordance with the RFC1867
procedures. The multipart/ form-data in the form is used. The
tag name “datafile” is used for the transfer.
Communication
specifications
HTTP/HTTPS
client
Supported versions 1.1
