How-to navigator

A collection of how to implement functions and function blocks for the OMRON NX/NJ series.
It covers FFT analysis, ring buffers, RecSSConvert, the SS recorder and MQTT connection with AWS IoT Core.
Following the steps gets things working, so use them as a base and adapt them

How-To Navigator List

FFT analysis procedure

Explains the steps for capturing analog data with a high-speed analog unit, performing FFT calculation and graphing the results on an HMI
We also output it to a CSV file and view it in Excel

How to use the ring buffer

Explains the steps for using a buffer when writing CSV files to an SD card

How to use RecSSConvert

Explains an application that converts data accumulated in structure arrays into files that can be imported into Sysmac Studio data trace
Files are continuously output to the SD card, and when needed they can be retrieved, converted to files importable into Sysmac Studio and checked

How to make the SS recorder

Creates files that can be imported into Sysmac Studio data trace with a program
The PLC continuously outputs files that can be imported into data trace, and when needed they can be retrieved and imported into Sysmac Studio to check the trace data
The PLC creates CSV files directly without the converter above, but the file size becomes larger

MQTT connection with AWS IoT Core

Creates the AWS IoT Core environment for connecting a PLC and AWS via MQTT and exchanging messages
