Hello NodeRed Users/Developers,  
We have SCADA application which generates high frequency alarms/events and stores in local SQL database. 1. We would like to know whether Node-RED module requires TLS 1.2 as a pre-requisites to read data from remote SCADA SQL DB? 2. Also Does Node-RED supports exception reporting i.e. whenever there is new alarm/event recorded in SQL DB, this needs to be published to ODBC client? 3. Can we install Node-RED on SCADA application machine? Will it cause any SCADA or OS performance issues? Which OS are the supported by Node-RED? 4.Can anyone please share relevant user manuals? Please forgive me for my questions here, as I do not have any experience in Node-RED.

1. It depends on the node-red module you pick for integrating with your database, but most provide different levels of security, from unsecured to the latest security standards.
2. Node-RED is an event-driven application. In this case, you would query the database or create a trigger mechanism to alert that there is a new alarm. It would be ideal to have the alarms in parallel sent directly to Node-RED and or an MQTT Broker.
3. Node-RED can be installed on Windows, Linux, and Apple computers. If installing Node-RED on a SCADA solution like WinCC is a concern and the OEM has strict rules about installing solutions on the same system, I would recommend either installing it on a separate server or running Docker. Node-RED doesn't require many resources.
4. Here is the [documentation](https://nodered.org/docs/getting-started/), but you can also find many YouTube videos and blogs online.

If you need help with this, let me know. Many professional services can guide you. Additionally, I work at [FlowFuse](https://flowfuse.com/), which manages your Node-RED deployments at scale for industrial use cases.
