Specifications Unique to the AI Controllers

Function Specifications of AI Functions

This section describes the AI Controller specifications that are unique to the AI Controllers.

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.

Time Series Database Function – General specifications

TimeSeries	Item	Specifications
TimeSeries common	Method	Time-series database (It uses a circular queue where the oldest data is deleted if it reaches the maximum number of data.)
	Number of TimeSeries	4
	Sampling start/stop method	It can be executed in any of the following methods: • AI Operator • System-defined variables • Instructions
	Export start/stop method	It can be executed in any of the following methods: • AI Operator • System-defined variables • Instructions
	Number of used variables with a Retain attribute	2 *1
Variable data (RAW_DATA)	Size of the TimeSeries	NX-series: 900 MB NY-series: 41 GB
	Number of variables [variables/record] *2	1024
	Category of variable	Global variable
	Variable type	The following variables can be specified: • Basic data types • Specifying array elements: • Specifying members of a structure or a union
Analysis data ANL_DATA)	Size of the TimeSeries database	NX-series: 1 GB NY-series: 30 GB
	Number of variables [variables/record] *2	2048 (including variable data, frame variables, subframe variables, and label variables)
	Category of variable	Global variable
	Variable type	The following variables can be specified: • Basic data types • Specifying array elements: • Specifying members of a structure or a union

*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.

WebAPI Connection Function – General specifications

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
		DNS	Supported
		Proxy	Supported
		Basic authentication	Supported (Basic authentication for the proxy server and Web server connection is supported.)
		Number of files that can be transferred simultaneously	3
	Security (when https:// is specified for the address)	TLS version	1.0, 1.1, 1.2
		Server certificates	Import the certificates to the AI Controller with the AI Operator. Up to 32 certificates can be set.
		Revocation check for the certificates	Revocation is checked by OSCP stapling.
