## Demo GUI for real-time data visualization | ||
|
||
>### Requirements: | ||
1) Simulation server (Eg. Prosys simulation server) | ||
2) IDE with python libraries installed | ||
3) MySql database | ||
4) OPCUA Python library | ||
|
||
>### Features: | ||
1) This script enables you to visualize the OPC values in real-time with the facility of data logging. | ||
2) An alert will be generated when the downtime reaches a threshold limit. | ||
3) Values can be adjusted as per the need. | ||
